via PNAS / April 2016 Significance Quantification of contamination risk caused by radioisotopes released from the Fukushima Dai-ichi nuclear power plant is useful for excluding or reducing groundless rumors about food safety. Our new statistical approach made it possible to evaluate the risk for aquatic food and showed that the present contamination levels of radiocesiums are low overall. However, some freshwater species still have relatively high risks. We also suggest … Continue reading →

By Takuya Isayama / Asahi Shimbun / January 7, 2016 / A virtual reality system here that will assist in the decommissioning of the crippled Fukushima No. 1 nuclear power plant is preparing for full-scale operations this spring. Located at the Naraha Remote Technology Development Center, the system features a 3.6-meter-high display that simulates 3-D images of the interiors of the reactor buildings at the Fukushima plant. The research and … Continue reading →

Three out of the six nuclear reactors in the plant melted down when the area was hit by a tsunami, which occurred as an after-effect of an earthquake. The 2011 catastrophe was the largest nuclear disaster since Chernobyl in April 1986. It is one of only a … Continue reading →

Four samples from these three locations show no detectable Fukushima cesium. We know this because Fukushima released equal amounts of two isotopes of cesium: the shorter-lived cesium-134 isotope (half-life of 2 years) and the longer-lived cesium-137 (half-life of 30 years). Cesium-137 was found … Continue reading →

While many people assume that the ocean will dilute the Fukushima radiation, a previously-secret 1955 U.S. government report concluded that the ocean may not adequately dilute radiation from nuclear accidents, and there could be “pockets” and “streams” of highly-concentrated radiation.
