In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes:
Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules, and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms. A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively. Other sources include X-rays from medical radiography examinations and muons, mesons, positrons, neutrons and other particles that constitute the secondary cosmic rays that are produced after primary cosmic rays interact with Earth's atmosphere.
The CNSC has produced a video designed to demystify radiation -- we answer the question What Is Radiation? The video features CNSC experts explaining the basics of radiation in simple terms -- what it is, the different types, radioisotopes, and radioactive decay.

From unbelievable three-eyed fish to all the terrifying pictures of radiation effects on humans and animals, like mutation it's bizarre! Subscribe to American Eye http://goo.gl/GBphkv 5. Three Eyed Fish You have seen a three eyed fish on this simpsons before name blinky who lived by the nuclear power plant where Homer Simpson worked. But could one of these mutated creatures actually exist? In 2011, this three eyed fish was caught near a nuclear power plant in Argentina in a local reservoir. A Spanish speaking new website, called infobae.com, claims this resevoir where the hot water from the nuclear facility is pumped, thus leaving radioactive particles in this body of water. Despite the fish not looking exactly the same as blinky, it makes you wonder what other negative ways radiation wi...
View full lesson: http://ed.ted.com/lessons/is-radiation-dangerous-matt-anticole When we hear the word radiation, it’s tempting to picture huge explosions and frightening mutations. But that’s not the full story — radiation also applies to rainbows and a doctor examining an X-ray. So what is it, really, and how much should we worry about its effects? Matt Anticole describes the different types of radiation. Lesson by Matt Anticole, animation by Tinmouse Animation Studio.
Who on Earth is exposed to the most ionizing radiation? Check out Audible: http://bit.ly/AudibleVe I'm filming a documentary for TV about how Uranium and radioactivity have shaped the modern world. It will be broadcast in mid-2015, details to come. The filming took me to the most radioactive places on Earth (and some places, which surprisingly aren't as radioactive as you'd think). Chernobyl and Fukushima were incredible to see as they present post-apocalyptic landscapes. I also visited nuclear power plants, research reactors, Marie Curie's institute, Einstein's apartment, nuclear medicine areas of hospitals, uranium mines, nuclear bomb sites, and interviewed numerous experts. Notes about measuring radiation: Sieverts are a measure of 'effective dose' - that means they measure the biologi...
Most people are familiar with the dangers of radiation. However, there is and has been a lot of misinformation and misunderstanding surrounding its effects. A lot of it stems from radiation's link to nuclear weapons. In fact, even the US government has made some very misleading statements about radiation in the past. For example, after dropping the nuclear bombs on Japan to end World War II, the US claimed that there wouldn't be any fallout radiation or that it wouldn't have any negative effects. Unfortunately, it did. Since then we have learned a lot about radiation and its effects on the human body as you will soon see with these 25 intense facts about radiation. Because of the misinformation in the past, there are lots of people who subscribe to somewhat pseudoscientific beliefs about ...
A quick demonstration of nuclear radiation. Just for fun and maybe even a little education. =)
Radiation is all around us and a part of everyday life. But what exactly is it and what does it do to our bodies?

Non-ionizing radiation includes the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF), and extremely low frequency (ELF). Lasers commonly operate in the UV, visible, and IR frequencies." Radiation Therapy- National Cancer Institute...
