Three types of plutonium have turned up amid the radioactive contamination on the grounds of the earthquake-damaged Fukushima Daiichi nuclear power plant, its owner reported Monday.

The plutonium is a byproduct of nuclear reactions that is also part of the fuel mix at the damaged No. 3 reactor.

It was found in soil at five different points inside the plant grounds, the Tokyo Electric Power Company said late Monday.

Plutonium can be a serious health hazard if inhaled or ingested, but external exposure poses little health risk, according to the U.S. Environmental Protection Agency.

钚的放射性比铀235高上万倍，半衰期仍有几万年，更要命的是剧毒。网上有信息说致命剂量只有几微克，一公斤的钚撒到汤锅里可以毒死全部的日本人口。3号堆有几百吨的核燃料，其中好像有9%的钚，流出1%就可以把日本人毒死上千次。如果流到海里不知道会毒死多少海洋生物，造成多大的放射性的剧毒污染。

因为钚的半衰期短（相对地球的寿命），自然界里是找不到钚的，都是人类在反应堆里造出来的。

他们吃拿河豚啥的。也许会有点抗毒了。 :lol
