In Nuclear Accident, Risks Extend Beyond Evacuation Zone
Wednesday 27 April 2011
Washington - The nuclear power accidents at Fukushima this spring and at Chernobyl 25 years ago Tuesday show that radiation releases can endanger people and contaminate land many miles beyond evacuation zones.
The advocacy group Physicians for Nuclear Responsibility, which opposes nuclear power, said Tuesday that the
Measurements of soil samples as far as 30 miles from the
Other measurements, at playgrounds outside the exclusion zone, showed levels equivalent to the limit of radiation permitted for an adult nuclear-plant worker. That amount would mean that one in 200 children would get cancer as a direct result of the exposure, Helfand said.
"Once they decide how to put the reactors into some sort of safe storage mode, they will need to deal with the contamination in and around the plants," said Kathryn Higley, a professor of radiation health physics at
When the cleanup phase begins, workers probably will use shovels to remove contaminated soil for disposal in a nuclear landfill, said Lake Barrett, a former official with the Department of Energy and the Nuclear Regulatory Commission who was involved in the cleanup of Three Mile Island in Pennsylvania after a nuclear accident there in 1979.
Some of the land that's cleaned up in

Physicians for Social Responsibility says the risks of nuclear power to public health and of nuclear proliferation are too high.
The group reported Tuesday that it had used a computer simulation to model what would happen in the case of a complete meltdown and massive release of radiation from a power plant in a metropolitan area. It studied Braidwood, outside
