A radioactive tracer, or radioactive label, is a chemical compound in which one or more atoms have been replaced by a radioisotope so by virtue of its radioactive decay it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products. Radiolabeling is thus the radioactive form of isotopic labeling.
Radioisotopes of hydrogen, carbon, phosphorus, sulphur, and iodine have been used extensively to trace the path of biochemical reactions. A radioactive tracer can also be used to track the distribution of a substance within a natural system such as a cell or tissue, or as a flow tracer to track fluid flow. Radioactive tracers are also used to determine the location of fractures created by hydraulic fracturing in natural gas production. Radioactive tracers form the basis of a variety of imaging systems, such as, PET scans, SPECT scans and technetium scans. Radiocarbon dating uses the naturally occurring carbon-14 isotope as an isotopic label.

Carbon has 15 known isotopes, from 8C to 22C, 2 of which are stable. The longest-lived radioisotope is 14C, with a half-life of 5,700 years. This is also the only carbon radioisotope found in nature—trace quantities are formed cosmogenically by the reaction 14N + 1n → 14C + 1H. The most stable artificial radioisotope is 11C, which has a half-life of 20.334 minutes. All other radioisotopes have half-lives under 20 seconds, most less than 200 milliseconds. The least stable isotope is 8C, with a half-life of 2.0 x 10−21 s. Averaging over natural abundances, the standard atomic mass for carbon is 12.0107(8) u.

http://en.wikipedia.org/wiki/Radionuclide
A radionuclide is an atom with an unstable nucleus, characterized by excess energy available to be imparted either to a newly created radiation particle within the nucleus or via internal conversion. During this process, the radionuclide is said to undergo radioactive decay, resulting in the emission of gamma ray(s) and/or subatomic particles such as alpha or beta particles. These emissions constitute ionizing radiation. Radionuclides occur naturally, or can be produced artificially.
Radionuclides are often referred to by chemists and physicists as radioactive isotopes or radioisotopes. Radioisotopes with suitable half-lives play an important part in a number of technologies (for example, nuclear medicine). Radionuclides can also present both real and perceived dangers to health.
The number of radionuclides is uncertain because the number of very short-lived radionuclides that have yet to be characterized is extremely large and potentially unquantifiable. Even the number of long-lived radionuclides is uncertain (to a lesser degree), because many "stable" nuclides are calculated to have half-lives so long that their decay has not been experimentally measured. The total list of nuclides contains 90 nuclides that are theoretically stable, and 255 total stable nuclides that have not been observed to decay. In addition, there exist about 650 radionuclides that have been experimentally observed to decay, with half-lives longer than 60 minutes (see list of nuclides for this list). Of these, about 339 are known from nature (they have been observed on Earth, and not as a consequence of man-made activities).
Including artificially produced nuclides, more than 3300 nuclides are known (including ~3000 radionuclides), many of which (over 2400) have decay half-lives shorter than 60 minutes. This list expands as new radionuclides with very short half-lives are characterized.
All elements form a number of radionuclides, although the half lives of many are too short for them to be observed in nature. Even the lightest element, hydrogen, has a well-known radioisotope, tritium. The heaviest elements (heavier than bismuth) exist only as radionuclides. For every chemical element, many radioisotopes that do not occur in nature (due to short half lives or the lack of an ongoing natural production mechanism), have been produced artificially...
http://en.wikipedia.org/wiki/Film_badge_dosimeter
The film badge dosimeter, or film badge, is a dosimeter used for monitoring cumulative exposure to ionizing radiation. The badge consists of two parts: photographic film or dental X-ray film, and a holder. The film is removed and developed to measure exposure. The film badge is used to measure and record radiation exposure due to gamma rays, X-rays and beta particles. It is essentially useless for measuring neutron radiation...
Description
The film is sensitive to radiation and, once developed, exposed areas increase in optical density (i.e. blacken) in response to incident radiation. One badge may contain several films of different sensitivities or, more usually, a single film with multiple emulsion coatings. The combination of a low-sensitivity and high-sensitivity emulsion extends the dynamic range to several orders of magnitude. Wide dynamic range is highly desirable as it allows measurement of very large accidental exposures without degrading sensitivity to more usual low level exposure...
http://en.wikipedia.org/wiki/Geiger_counter
A Geiger--Müller counter, also called a Geiger counter, is a type of particle detector that measures ionizing radiation. It detects the emission of nuclear radiation: alpha particles, beta particles or gamma rays by the ionization produced in a low-pressure gas in a Geiger--Müller tube, which gives its name to the instrument.
The original operating principle was discovered in 1908 and Geiger counters remain popular instruments for use in radiation dosimetry, health physics, experimental physics, the nuclear industry, geological exploration...

“The most noteworthy are the pyroxenitic clasts, which occur in large, crystalline masses up to 8 cm --3 in-- in size in many hand specimens and are clearly of plutonic origin. They consist of xenomorphic-granular and tightly intergrown, coarse enstatite , with minor primary diopside , and accessory kamacite, taenite, titanoan troilite, oldhamite [CaS], and caswellsilverite. Xenomorphic plagioclase occurs in the interstices between enstatite grains and forms myrmekitic intergrowths with silica ----probably tridymite. Casanova, Keil, and Newsom studied the mineralogy and trace element composition of metal and metal nodules, up to 1.5 cm in size, in the Norton County aubrite and concluded that the metal did not undergo fractional crystallization in a core but, rather, is a fraction of the metallic Fe-Ni which, during partial melting of an enstatite chondrite-like precursor lithology, was not completely segregated from the silicates.
“A remarkable, oldhamite-dominated igneous lithology consists of clasts containing oldhamite [CaS] single crystals up to 2 cm (0.8 in) in size, with inclusions of ferromagnesian alabandite [MnS], troilite, daubreelite [FeCr2S4], caswellsilverite [NaCrS2], and metallic Fe-Ni, which are usually in intimate contact with a silicate portion consisting of enstatite, forsterite, and/or plagioclase and testify to the formation of the oldhamite from a melt.
“The Shallowater aubrite was found in Lubbock County, Texas in 1936 and weighed in at 4.6 kg --10 lb. It is a non-brecciated, coarse-grained orthopyroxenite that consists of large, up to 4.5 cm --1.8 in, subhedral poikilitic orthoenstatite crystals --up to 80 vol.% which enclose smaller orthoenstatite crystals of identical composition and which also contain as inclusions and in the interstices xenoliths of an assemblage of low-Ca clinoenstatite --1 vol.%, forsterite --Mg-olivine --2.9 vol.%, plagioclase --2.5 vol.%, metallic Fe-Ni --3.3 vol.%, which is more than five times more than in other aubrites, troilite --2.9 vol.%, schreibersite --0.4 vol.%, weathered opaques --8 vol.%, and traces of niningerite --a magnesium-iron-manganese sulfide and oldhamite [CaS].
“Regarded as definitely of igneous origin, the rock is deduced to have experienced a complex, three-stage cooling history, which prompted Keil et al. to suggest that its distinct parent body formed by the reassembly of the debris from the collision of a partly or totally molten enstatite-rich aubrite-like body with a solid, enstatite-chondrite-like body represented by the xenoliths, followed by rapid cooling and crystallization. They also suggested that this was not the main aubrite parent body (asteroid) from which other aubrites came, but rather that Shallowater represents a sample from a second different aubrite parent body.....

Track and trace increases efficiency, assures quality and provides visibility to a project. Amec Foster Wheeler, along with technology partner DAI, are successfully using this innovative technology in the oil and gas industry, both onshore and offshore. This allows us to track materials from requisition to the worksite.
We achieved 99.96% accuracy in materials being shipped and issued to engineers offshore. This equates to an estimated £750,000 cost saving through the removal of unnecessary procurement, associated logistics costs and offshore non-productive time relating to materials being unavailable. It is results like these that helped us win the EIC Supply Chain Excellence Award 2014.

The Answers In Genesis website published the above article written by Dr. Elizabeth Mitchell on May 2, 2015. I now quote his article below:
“Trickle-down chemistry supposedly solves the chemical conundrum concerning the origin of life, but molecules-to-man evolution remains as fictional and imaginative as ever.
“News Sources
Science: “Researchers May Have Solved Origin-of-Life Conundrum”; Science News: “Cooking Up Life’s Ingredients, All in One Pot”; Mapping Ignorance: “Living Beings: Systems All the Way Back to Their Chemical Origins”
“Editor’s note: This article presents the latest claims concerning the evolutionary origin of life and, updating a previous article on the subject, points out that the supposed answer is no answer at all.
“Cells, as everybody knows, are made of those complex organic molecules; yet the latter come to existence and play a role by virtue of an intricate web of dynamic inter-relationships and transformation processes, which in practice holds all of them together. Remarkably, most biomolecules (except for DNA) have relatively short ‘lifetimes’, much shorter than the lifetime of the collective entity they integrate. Each living organism is a molecular factory in continuous turnover, whose far from equilibrium activity is maintained precisely thanks to the generation of all those structures that are required to build the factory up and keep it running.
“Without the factory the various pieces, their sheer existence and purpose, just would not make sense: each is produced and has a function in the context of the activity of all the others. If this fact is seriously assimilated, it becomes obvious that the first appearance of something resembling a living being could not be thanks to molecules of a single type. It would be easier to study if it were in that way, no doubt, but life is hard — also for researchers in the field of origins.
“After this ode to the irreducible complexity of the living cell, Ruiz-Mirazo expresses confidence that modern chemistry will ultimately solve the problem. “Scientists interested in the chemistry-biology gap will find, at last, a natural bridge between the two,” he says, enabling us to “cross that river, deep and wide, that still separates us from our chemical roots” knowing that “Nature became a ‘perfect queen’ in these affairs long ago: the integration of diverse molecular components performing different tasks within a complex organization surely started at a proto-cellular stage, long before natural selection pushed the birth of more robust, full-fledged living cells — made of DNA, RNA and proteins.”
“Yet these authors still overlook the key component, the element evolutionists are unable to conjure through naturalistic processes: Information. Whether information to become alive in the first place, or information to naturalistically progress all the way up the tree of life, evolutionary science suffers from an appalling lack of information.
“What is the source of the information evolutionists seek in vain? Answers in Genesis molecular geneticist Dr. Georgia Purdom has summed it up well:
“The river between non-life and life is indeed "deep and wide" and cannot be crossed by a deeper or better understanding of biology and chemistry. Information is required for life and without an information-giver life cannot come about by random chance from a chemical soup. As researchers continue to search for that “magic bullet” to understand the origin of life, they will continue to be frustrated and in their rebellious hearts fail to acknowledge that life can only come from the one true Life-Giver, the Creator God.” Thank God for Dr Mitchell.

A trace radioisotope is a radioisotope that occurs naturally in trace amounts (i.e. extremely small). Generally speaking, trace radioisotopes have half-lives that are short in comparison to the age of the earth, since primordial nuclides tend to occur in larger than trace amounts. Trace radioisotopes are therefore present only because they are continually produced on Earth by natural processes. One exception to this rule is Plutonium-244 which, with a half-life of about 80 million years, is just barely stable enough that some of it has remained from the Earth's formation. Natural processes which produce trace radioisotopes include cosmic ray bombardment of stable nuclides, ordinary alpha and beta decay of the long-lived heavy nuclides, Thorium-232, Uranium-238, and Uranium-235, spontaneous fission of natural Uranium-238, and nuclear transmutation reactions induced by natural radioactivity, such as the production of Plutonium-239 and Uranium-236 from neutron capture by natural uranium.
The elements that are created from decay are listed below.

Carbon has 15 known isotopes, from 8C to 22C, 2 of which are stable. The longest-lived radioisotope is 14C, with a half-life of 5,700 years. This is also the only carbon radioisotope found in nature—trace quantities are formed cosmogenically by the reaction 14N + 1n → 14C + 1H. The most stable artificial radioisotope is 11C, which has a half-life of 20.334 minutes. All other radioisotopes have half-lives under 20 seconds, most less than 200 milliseconds. The least stable isotope is 8C, with a half-life of 2.0 x 10−21 s. Averaging over natural abundances, the standard atomic mass for carbon is 12.0107(8) u. This video is targeted to blind users.

Track and trace - innovative technology
Track and trace increases efficiency, assures quality and provides visibility to a project. Amec Foster Wheeler, along with technology partner DAI, are successfully using this innovative technology in the oil and gas industry, both onshore and offshore. This allows us to track materials from requisition to the worksite. We achieved 99.96% accuracy in materials being shipped and issued to engineers offshore. This equates to an estimated £750,000 cost saving through the removal of unnecessary procurement, associated logistics costs and offshore non-productive time relating to materials being unavailable. It is results like these that helped us win the EIC Supply Chain Excellence Award 2014. -

Plutonium Commercial
Plutonium is a transuranic radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon and hydrogen. When exposed to moist air, it forms oxides and hydrides that expand the sample up to 70% in volume, which in turn flake off as a powder that can spontaneously ignite. It is radioactive and can accumulate in bones. These properties make the handling of plutonium dangerous. A team led by Glenn T. Seaborg and Edwin McMillan at the University of California, Berkeley, first synthesized plutonium in 1940 by bombarding uranium-238 with deute... -
Neptunium - Video Learning - WizScience.com
"Neptunium" is a chemical element with symbol "Np" and atomic number 93. A radioactive actinide metal, neptunium is the first transuranic element. Its position in the periodic table just after uranium, named after the planet Uranus, led to it being named after Neptune, the next planet beyond Uranus. A neptunium atom has 93 protons and 93 electrons, of which seven are valence electrons. Neptunium metal is silvery and tarnishes when exposed to air. The element occurs in three allotropic forms and it normally exhibits five oxidation states, ranging from +3 to +7. It is radioactive, pyrophoric, and can accumulate in bones, which makes the handling of neptunium dangerous. Although many false claims of its discovery were made over the years, the element was first synthesized by Edwin McMillan... -
ExoMars - Video Learning - WizScience.com
"ExoMars" is a large Mars mission to search for biosignatures of Martian life, past or present. This astrobiology mission is currently under development by the European Space Agency in collaboration with the Russian Federal Space Agency . The programme includes several spacecraft elements to be sent to Mars on two launches. The ExoMars Trace Gas Orbiter and an EDM stationary lander called 'Schiaparelli' are planned for 2016. The TGO would deliver the ESA-built stationary lander and then proceed to map the sources of methane on Mars and other gases, and in doing so, help select the landing site for the ExoMars rover to be launched in 2018 on a Russian heavy lift Proton launch vehicle. The TGO will feature four instruments and will also act as the communication relay satellite for the... -
Radiometric dating
Radiometric dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they formed. The method compares the abundance of a naturally occurring radioactive isotope within the material and the abundance of its decay products, which form at a known constant rate of decay. The use of radiometric dating was first published in 1907 by Bertram Boltwood and is now the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials. Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale. Among the best... -
Iodine - Video Learning - WizScience.com
"Iodine" is a chemical element with symbol "I" and atomic number 53. The name is from Greek "ioeidēs", meaning violet or purple, due to the color of elemental iodine vapor. Iodine and its compounds are primarily used in nutrition, and industrially in the production of acetic acid and certain polymers. Iodine's relatively high atomic number, low toxicity, and ease of attachment to organic compounds have made it a part of many X-ray contrast materials in modern medicine. Iodine has only one stable isotope. A number of iodine radioisotopes, such as 131 I, are also used in medical applications. Iodine is found on Earth mainly as the highly water-soluble iodide ion I − , which concentrates it in oceans and brine pools. Like the other halogens, free iodine occurs mainly as a diatomic mol...

A radioactive tracer, or radioactive label, is a chemical compound in which one or more atoms have been replaced by a radioisotope so by virtue of its radioactive decay it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products. Radiolabeling is thus the radioactive form of isotopic labeling.
Radioisotopes of hydrogen, carbon, phosphorus, sulphur, and iodine have been used extensively to trace the path of biochemical reactions. A radioactive tracer can also be used to track the distribution of a substance within a natural system such as a cell or tissue, or as a flow tracer to track fluid flow. Radioactive tracers are also used to determine the location of fractures created by hydraulic fracturing in natural gas production. Radioactive tracers form the basis of a variety of imaging systems, such as, PET scans, SPECT scans and technetium scans. Radiocarbon dating uses the naturally occurring carbon-14 isotope as an isotopic label.

http://en.wikipedia.org/wiki/Radionuclide
A radionuclide is an atom with an unstable nucleus, characterized by excess energy available to be imparted either to a newly created radiation particle within the nucleus or via internal conversion. During this process, the radionuclide is said to undergo radioactive decay, resulting in the emission of gamma ray(s) and/or subatomic particles such as alpha or beta particles. These emissions constitute ionizing radiation. Radionuclides occur naturally, or can be produced artificially.
Radionuclides are often referred to by chemists and physicists as radioactive isotopes or radioisotopes. Radioisotopes with suitable half-lives play an important part in a number of technologies (for example, nuclear medicine). Radionuclides can also present both real and perceived dangers to health.
The number of radionuclides is uncertain because the number of very short-lived radionuclides that have yet to be characterized is extremely large and potentially unquantifiable. Even the number of long-lived radionuclides is uncertain (to a lesser degree), because many "stable" nuclides are calculated to have half-lives so long that their decay has not been experimentally measured. The total list of nuclides contains 90 nuclides that are theoretically stable, and 255 total stable nuclides that have not been observed to decay. In addition, there exist about 650 radionuclides that have been experimentally observed to decay, with half-lives longer than 60 minutes (see list of nuclides for this list). Of these, about 339 are known from nature (they have been observed on Earth, and not as a consequence of man-made activities).
Including artificially produced nuclides, more than 3300 nuclides are known (including ~3000 radionuclides), many of which (over 2400) have decay half-lives shorter than 60 minutes. This list expands as new radionuclides with very short half-lives are characterized.
All elements form a number of radionuclides, although the half lives of many are too short for them to be observed in nature. Even the lightest element, hydrogen, has a well-known radioisotope, tritium. The heaviest elements (heavier than bismuth) exist only as radionuclides. For every chemical element, many radioisotopes that do not occur in nature (due to short half lives or the lack of an ongoing natural production mechanism), have been produced artificially...
http://en.wikipedia.org/wiki/Film_badge_dosimeter
The film badge dosimeter, or film badge, is a dosimeter used for monitoring cumulative exposure to ionizing radiation. The badge consists of two parts: photographic film or dental X-ray film, and a holder. The film is removed and developed to measure exposure. The film badge is used to measure and record radiation exposure due to gamma rays, X-rays and beta particles. It is essentially useless for measuring neutron radiation...
Description
The film is sensitive to radiation and, once developed, exposed areas increase in optical density (i.e. blacken) in response to incident radiation. One badge may contain several films of different sensitivities or, more usually, a single film with multiple emulsion coatings. The combination of a low-sensitivity and high-sensitivity emulsion extends the dynamic range to several orders of magnitude. Wide dynamic range is highly desirable as it allows measurement of very large accidental exposures without degrading sensitivity to more usual low level exposure...

“The most noteworthy are the pyroxenitic clasts, which occur in large, crystalline masses up to 8 cm --3 in-- in size in many hand specimens and are clearly of plutonic origin. They consist of xenomorphic-granular and tightly intergrown, coarse enstatite , with minor primary diopside , and accessory kamacite, taenite, titanoan troilite, oldhamite [CaS], and caswellsilverite. Xenomorphic plagioclase occurs in the interstices between enstatite grains and forms myrmekitic intergrowths with silica ----probably tridymite. Casanova, Keil, and Newsom studied the mineralogy and trace element composition of metal and metal nodules, up to 1.5 cm in size, in the Norton County aubrite and concluded that the metal did not undergo fractional crystallization in a core but, rather, is a fraction of the metallic Fe-Ni which, during partial melting of an enstatite chondrite-like precursor lithology, was not completely segregated from the silicates.
“A remarkable, oldhamite-dominated igneous lithology consists of clasts containing oldhamite [CaS] single crystals up to 2 cm (0.8 in) in size, with inclusions of ferromagnesian alabandite [MnS], troilite, daubreelite [FeCr2S4], caswellsilverite [NaCrS2], and metallic Fe-Ni, which are usually in intimate contact with a silicate portion consisting of enstatite, forsterite, and/or plagioclase and testify to the formation of the oldhamite from a melt.
“The Shallowater aubrite was found in Lubbock County, Texas in 1936 and weighed in at 4.6 kg --10 lb. It is a non-brecciated, coarse-grained orthopyroxenite that consists of large, up to 4.5 cm --1.8 in, subhedral poikilitic orthoenstatite crystals --up to 80 vol.% which enclose smaller orthoenstatite crystals of identical composition and which also contain as inclusions and in the interstices xenoliths of an assemblage of low-Ca clinoenstatite --1 vol.%, forsterite --Mg-olivine --2.9 vol.%, plagioclase --2.5 vol.%, metallic Fe-Ni --3.3 vol.%, which is more than five times more than in other aubrites, troilite --2.9 vol.%, schreibersite --0.4 vol.%, weathered opaques --8 vol.%, and traces of niningerite --a magnesium-iron-manganese sulfide and oldhamite [CaS].
“Regarded as definitely of igneous origin, the rock is deduced to have experienced a complex, three-stage cooling history, which prompted Keil et al. to suggest that its distinct parent body formed by the reassembly of the debris from the collision of a partly or totally molten enstatite-rich aubrite-like body with a solid, enstatite-chondrite-like body represented by the xenoliths, followed by rapid cooling and crystallization. They also suggested that this was not the main aubrite parent body (asteroid) from which other aubrites came, but rather that Shallowater represents a sample from a second different aubrite parent body.....

The Answers In Genesis website published the above article written by Dr. Elizabeth Mitchell on May 2, 2015. I now quote his article below:
“Trickle-down chemistry supposedly solves the chemical conundrum concerning the origin of life, but molecules-to-man evolution remains as fictional and imaginative as ever.
“News Sources
Science: “Researchers May Have Solved Origin-of-Life Conundrum”; Science News: “Cooking Up Life’s Ingredients, All in One Pot”; Mapping Ignorance: “Living Beings: Systems All the Way Back to Their Chemical Origins”
“Editor’s note: This article presents the latest claims concerning the evolutionary origin of life and, updating a previous article on the subject, points out that the supposed answer is no answer at all.
“Cells, as everybody knows, are made of those complex organic molecules; yet the latter come to existence and play a role by virtue of an intricate web of dynamic inter-relationships and transformation processes, which in practice holds all of them together. Remarkably, most biomolecules (except for DNA) have relatively short ‘lifetimes’, much shorter than the lifetime of the collective entity they integrate. Each living organism is a molecular factory in continuous turnover, whose far from equilibrium activity is maintained precisely thanks to the generation of all those structures that are required to build the factory up and keep it running.
“Without the factory the various pieces, their sheer existence and purpose, just would not make sense: each is produced and has a function in the context of the activity of all the others. If this fact is seriously assimilated, it becomes obvious that the first appearance of something resembling a living being could not be thanks to molecules of a single type. It would be easier to study if it were in that way, no doubt, but life is hard — also for researchers in the field of origins.
“After this ode to the irreducible complexity of the living cell, Ruiz-Mirazo expresses confidence that modern chemistry will ultimately solve the problem. “Scientists interested in the chemistry-biology gap will find, at last, a natural bridge between the two,” he says, enabling us to “cross that river, deep and wide, that still separates us from our chemical roots” knowing that “Nature became a ‘perfect queen’ in these affairs long ago: the integration of diverse molecular components performing different tasks within a complex organization surely started at a proto-cellular stage, long before natural selection pushed the birth of more robust, full-fledged living cells — made of DNA, RNA and proteins.”
“Yet these authors still overlook the key component, the element evolutionists are unable to conjure through naturalistic processes: Information. Whether information to become alive in the first place, or information to naturalistically progress all the way up the tree of life, evolutionary science suffers from an appalling lack of information.
“What is the source of the information evolutionists seek in vain? Answers in Genesis molecular geneticist Dr. Georgia Purdom has summed it up well:
“The river between non-life and life is indeed "deep and wide" and cannot be crossed by a deeper or better understanding of biology and chemistry. Information is required for life and without an information-giver life cannot come about by random chance from a chemical soup. As researchers continue to search for that “magic bullet” to understand the origin of life, they will continue to be frustrated and in their rebellious hearts fail to acknowledge that life can only come from the one true Life-Giver, the Creator God.” Thank God for Dr Mitchell.

Lee Ann McAdoo interviews Doctor Edward Group, who explains how iodine deficiency is harming women's health across the board.
To detoxify your body from radioisotopes, Doctor Edward Group recommends:
- Nascent iodine;
- Bentonite clay
- Epsom salt bath
- Zeolites
- Activated charcoal
- A clean healthy diet, including e.g. spiralina and chlorella
Doctor Edward Group is a medical expert in total body detox, a vital move in the aggressive biochemical environment of today (GMO, ionizing radiation, electromagnetic radiation, processed foods, heavy metals in the environment and in vaccines, etc.) He is working on the benefits of nascent iodine and other vital supplements. His and others' work is particularly relevant in the wake of Fukushima, a global reaching nuclear disaster.

Plutonium is a transuranic radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon and hydrogen. When exposed to moist air, it forms oxides and hydrides that expand the sample up to 70% in volume, which in turn flake off as a powder that can spontaneously ignite. It is radioactive and can accumulate in bones. These properties make the handling of plutonium dangerous.
A team led by Glenn T. Seaborg and Edwin McMillan at the University of California, Berkeley, first synthesized plutonium in 1940 by bombarding uranium-238 with deuterons. Plutonium is the heaviest primordial element by virtue of its most stable isotope, plutonium-244, whose half-life of about 80 million years is just long enough for the element to be found in trace quantities in nature. Plutonium is mostly a byproduct of nuclear reactions, where some of the neutrons released by the fission process convert uranium-238 nuclei into plutonium.
Both plutonium-239 and plutonium-241 are fissile, meaning that they can sustain a nuclear chain reaction, leading to applications in nuclear weapons and nuclear reactors. Plutonium-240 exhibits a high rate of spontaneous fission, raising the neutron flux of any sample containing it. The presence of plutonium-240 limits a plutonium sample's usability for weapons or its quality as reactor fuel, and the percentage of plutonium-240 determines its grade (weapons-grade, fuel-grade, or reactor-grade). Plutonium-238 has a half-life of 88 years and emits alpha particles. It is a heat source in radioisotope thermoelectric generators, which are used to power some spacecraft. Plutonium isotopes are expensive and inconvenient to separate, so particular isotopes are usually manufactured in specialized reactors.
Producing plutonium in useful quantities for the first time was a major part of the Manhattan Project during World War II, which developed the first atomic bombs. The Fat Man bombs used in the Trinity nuclear test in July 1945, and in the bombing of Nagasaki in August 1945, had plutonium cores. Human radiation experiments studying plutonium were conducted without informed consent, and several criticality accidents, some lethal, occurred after the war. Disposal of plutonium waste from nuclear power plants and dismantled nuclear weapons built during the Cold War is a nuclear-proliferation and environmental concern. Other sources of plutonium in the environment are fallout from numerous above-ground nuclear tests, now banned.

"Neptunium" is a chemical element with symbol "Np" and atomic number 93. A radioactive actinide metal, neptunium is the first transuranic element. Its position in the periodic table just after uranium, named after the planet Uranus, led to it being named after Neptune, the next planet beyond Uranus. A neptunium atom has 93 protons and 93 electrons, of which seven are valence electrons. Neptunium metal is silvery and tarnishes when exposed to air. The element occurs in three allotropic forms and it normally exhibits five oxidation states, ranging from +3 to +7. It is radioactive, pyrophoric, and can accumulate in bones, which makes the handling of neptunium dangerous.
Although many false claims of its discovery were made over the years, the element was first synthesized by Edwin McMillan and Philip H. Abelson at the Berkeley Radiation Laboratory in 1940. Since then, most neptunium has been and still is produced by neutron irradiation of uranium in nuclear reactors. The vast majority is generated as a by-product in conventional nuclear power reactors. While neptunium itself has no commercial uses at present, it is widely used as a precursor for the formation of plutonium-238, used in radioisotope thermal generators. Neptunium has also been used in detectors of high-energy neutrons.
The most stable isotope of neptunium, neptunium-237, is a by-product of nuclear reactors and plutonium production. It, and the isotope neptunium-239, are also found in trace amounts in uranium ores due to neutron capture reactions and beta decay.

"ExoMars" is a large Mars mission to search for biosignatures of Martian life, past or present. This astrobiology mission is currently under development by the European Space Agency in collaboration with the Russian Federal Space Agency . The programme includes several spacecraft elements to be sent to Mars on two launches. The ExoMars Trace Gas Orbiter and an EDM stationary lander called 'Schiaparelli' are planned for 2016. The TGO would deliver the ESA-built stationary lander and then proceed to map the sources of methane on Mars and other gases, and in doing so, help select the landing site for the ExoMars rover to be launched in 2018 on a Russian heavy lift Proton launch vehicle. The TGO will feature four instruments and will also act as the communication relay satellite for the follow up rover. In 2018 a Roscosmos-built lander is to deliver the ESA-built rover to the martian surface. The rover will also include some Roscosmos built instruments. The mission will be guided from Italy.
Since its inception, ExoMars has gone through several phases of planning with various proposals for landers, orbiters, launch vehicles, and international cooperation planning, such as the defunct 2009 Mars Exploration Joint Initiative with the United States.
Originally, the ExoMars concept consisted of a large robotic rover being part of ESA's Aurora programme as a "Flagship mission" and was approved by the European Space Agency ministers in December 2005. Originally conceived as a rover with a stationary ground station, ExoMars was planned to launch in 2011 aboard a Russian Soyuz Fregat rocket.

"ExoMars" is a large Mars mission to search for biosignatures of Martian life, past or present. This astrobiology mission is currently under development by the European Space Agency in collaboration with the Russian Federal Space Agency . The programme includes several spacecraft elements to be sent to Mars on two launches. The ExoMars Trace Gas Orbiter and an EDM stationary lander called 'Schiaparelli' are planned for 2016. The TGO would deliver the ESA-built stationary lander and then proceed to map the sources of methane on Mars and other gases, and in doing so, help select the landing site for the ExoMars rover to be launched in 2018 on a Russian heavy lift Proton launch vehicle.

Radiometric dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they formed. The method compares the abundance of a naturally occurring radioactive isotope within the material and the abundance of its decay products, which form at a known constant rate of decay. The use of radiometric dating was first published in 1907 by Bertram Boltwood and is now the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials.
Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale. Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts.

"Iodine" is a chemical element with symbol "I" and atomic number 53. The name is from Greek "ioeidēs", meaning violet or purple, due to the color of elemental iodine vapor.
Iodine and its compounds are primarily used in nutrition, and industrially in the production of acetic acid and certain polymers. Iodine's relatively high atomic number, low toxicity, and ease of attachment to organic compounds have made it a part of many X-ray contrast materials in modern medicine. Iodine has only one stable isotope. A number of iodine radioisotopes, such as 131 I, are also used in medical applications.
Iodine is found on Earth mainly as the highly water-soluble iodide ion I − , which concentrates it in oceans and brine pools. Like the other halogens, free iodine occurs mainly as a diatomic molecule I 2 , and then only momentarily after being oxidized from iodide by an oxidant like free oxygen. In the universe and on Earth, iodine's high atomic number makes it a relatively rare element. However, its presence in ocean water has given it a role in biology. It is the heaviest essential element utilized widely by life in biological functions . Iodine's rarity in many soils, due to initial low abundance as a crust-element, and also leaching of soluble iodide by rainwater, has led to many deficiency problems in land animals and inland human populations. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities.
Iodine is required by higher animals for synthesizing thyroid hormones, which contain the element. Because of this function, radioisotopes of iodine are concentrated in the thyroid gland along with nonradioactive iodine. If inhaled, the radioisotope iodine-131, which has a high fission product yield, concentrates in the thyroid, but is easily remedied with non-radioactive potassium iodide treatment.
