Nuclear explosion in Japan won't cause cancer according to report
NBC News — Although Japanese citizens were exposed to radiation during last year's nuclear crisis, the World Health Organization says it wasn't enough to cause cancer. The organization has released a preliminary report on estimated radiation exposure over four months after the accident at the Fukushima Daiichi nuclear plant. Estimates were based on the results of a Japanese government survey of soil and food products.
According to the report, Japanese citizens were exposed to up to 50 millisieverts of radiation, but no part of the country saw exposure exceeding the cancer-risk level of 100 millisieverts. The WHO says the estimates may be too high because they assume people remained in their communities near the plant for four months after the nuclear accident when many people actually left. The WHO plans to release a final report in July including a comprehensive assessment of the nuclear accident's impact on people's health.
