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 U.S. 10-mile evacuation plan was inadequate and should be extended to 50 miles. One-third of the U.S. population lives within 50 miles of nuclear power plants.
In Japan, much of the radiation plume went over the Pacific Ocean in the early weeks after the March 11 earthquake and tsunami, but wind's and rain drove some of it onto land. The release of radioactive materials raises the risk of cancer, especially for children, who are more vulnerable than adults, Ira Helfand, a member of Physicians for Social Responsibility, said at a news conference.
The Chernobyl accident in 1986 in the former Soviet Union contaminated 58,000 square miles of land, stretching as far as 300 miles north of the plant, the International Atomic Energy Agency reported. Unlike the Fukushima plants or U.S. plants, Chernobyl had no concrete and steel structure to contain accidental releases.
