Fairewinds analyzes cancer rates for young children near Fukushima using the National Academy of Science’s BEIR (Biological Effects of Ionizing Radiation) VII Report. Based on BEIR VII, Fairewinds determines that at least one in every 100 young girls will develop cancer for every year they are exposed to 20 millisieverts [millisievert (1 mSv = 0.001 Sv)] of radiation. The 20-millisievert/ year figure is what the Japanese government is currently calculating as the legal limit of radiological exposure to allow habitation of contaminated areas near the Fukushima Daiichi nuclear power plant. In this video, Fairewinds introduces additional analysis by Ian Goddard showing that the BEIR VII report underestimates the true cancer rates to young children living near Fukushima Daiichi. Looking at the scientific data presented by Mr. Goddard, Fairewinds has determined that at least one out of every 20 young girls (5%) living in an area where the radiological exposure is 20 millisieverts for five years will develop cancer in their lifetime.
