Crippled Fukushima Reactors Are Still a Danger, 5 Years after the Accident
Japans citizens, and scientists worldwide, do not have answers to basic health and environment questions
By Madhusree Mukerjee on March 8, 2016
On March 11, 2011, a giant tsunami from the Pacific Ocean swept over the 10-meter sea wall surrounding six reactors at the Fukushima power plant on Japans east coast. The crashing water caused reactor cores to overheat and melt, and subsequent hydrogen explosions damaged three reactor buildings. Radiation spewed in every direction. The country shut down all of its more than 40 reactors, and investigations began into radiation exposure to tens of thousands of nearby residents, as well as to wildlife on land and sea. But major questions still loom today, in part because the damaged reactors are too dangerous to enter, and in part because the plant's operator, the Tokyo Electric Power Company (Tepco), is reluctant to share information.

Meanwhile, after five years, some 100,000 people are still waiting to return to their homes. Last year the Japanese government announced that it will eventually lift evacuation orders for regions where a person would receive an annual radiation dose of 20 millisieverts or less. That figure, several times higher than what the International Commission on Radiological Protection recommends for safety, poses an "unacceptable" risk, Matsukubo says. (According to a report from the U.S. National Academy of Sciences, a dose of 20 millisieverts increases the chances of mortality from cancer by roughly one in 1,000, and residents would be receiving comparable doses year after year.) No matter: a year after this zone is opened up, Tepco will stop providing compensation to its 32,000 former residents. Exile may be permanent, however, for tens of thousands of people from the most contaminated areas.

One reason is the scarcity of funds for such research, argues Mousseau. The Japanese government seems to be cutting off funds for monitoring radionuclides in water alongside Fukushima, Buesseler says. Shibata finds such concerns "biased," pointing out that several ministries offer funds for environmental research. But another Japanese scientist, who asked not to be named, claimed that whereas grants are readily available for researchers whose projects are unlikely to discover significant impacts from the disaster, they are exceedingly scarce for others.
Other muddiness remains. Several Japanese researchers who aided Mousseau's team asked not to be credited in its published papers, fearing adverse impacts on their careers. Buesseler reports a similar experience. "There's this kind of self-censorship going on," Mousseau says.
