When did the radiation start to leak from Fukushima Daiichi Nuclear Power Plant and how far has it spread?
About this our greatest interest, the Japanese Government announced nothing for several days (at least until March 17) after the earthquake occurred on March 11, 2011. They just described the facts saying they “….happened” in the past tense, explaining neither the cause of the explosion nor its mechanism. They never talked about expectations of danger. What is “the worst scenario” that this nuclear accident might lead to? A reporter asked this of Edano Yukio, Chief Cabinet Secretary, at a news conference, but whether because Edano couldn’t answer or didn’t want to, he said nothing clearly.
