Uranium mine workers in the Northern Territory are still not on the National Radiation Dose Register, five months after their exclusion was revealed by the Australian Greens.

Greens Senator Scott Ludlam exposed the information black hole during Estimates hearings in May, and today while quizzing representatives from the Australian Radiation Protection and Nuclear Safety Agency discovered that nothing had been done to fix it.

The Barnett Government's costly support for uranium mining in Western Australia will leave the state littered with long-term environmental disasters, the Greens warned today.

The State Government has thrown away more than one million dollars encouraging uranium mining in just the first three quarters of 2010/11.

Senator for Western Australia Scott Ludlam said the ongoing problems plaguing Ranger mine in the Northern Territory and the decades-long multi-million dollar clean up of the defunct Rum Jungle mine illustrated the danger of uranium mining.

Uranium mine workers in the Northern Territory have not been included in the National Radiation Dose Register, the Australian Greens revealed today.

Senator for Western Australia Scott Ludlam uncovered the loophole during Senate Estimates hearings today while quizzing representatives from the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA).

"On July 1, 2010, the register began collecting data on the radiation doses to which workers had been exposed. Covering five years, the register now has 16,000 individuals on the database but has no information on the radiation workers have been exposed to at the Ranger Mine in the Northern Territory," said Senator Ludlam.
