An excellent article in the New York Times today about the perceived radiation risks in Fukushima. US experts believe that those risks are quite a bit higher than estimated in Japan.
The Nuclear Regulatory Commission (NRC), so states the article, gives a significantly bleaker appraisal of the threat posed by Fukushima, saying that the damage at one of the reactors was much more serious than acknowledged in Japan. Americans are advised to evacuate from an area much larger than the safety zone established by the Japanese.
Japan started its fifth day in the fight for control of the reactors in Fukushima after their cooling systems were knocked out by the earthquake and tsunami. I’ve been impressed by the efforts of the Japanese, although Japanese officials are criticized for not seeking outside support early enough and supplying insufficient information about the situation. The new statement by the NRC adds a bit more fuel to this fire.
