pu

钚（Plutonium ），原子序数为94，元素符号是Pu，是一种具放射性的超铀元素。半衰期为24万5千年。它属于锕系金属，外表呈银白色，接触空气后容易锈蚀、氧化，在表面生成无光泽的二氧化钚。

钚有六种同位素和四种氧化态，易和碳、卤素、氮、硅起化学反应。钚暴露在潮湿的空气中时会产生氧化物和氢化物，其体积最大可膨胀70%，屑状的钚能自燃。它也是一种放射性毒物，会于骨髓中富集。因此，操作、处理钚元素具有一定的危险性。

钚的半衰期是多少年

钚的半衰期是8.2×107年。

钚plutonium一种化学元素。化学符号Pu，原子序数94，属周期系ⅢB族，为锕系元素的成员和人工放射性元素。半衰期最长的同位素是钚244。1940年美国G.T.西博格、E.M.麦克米伦、J.W.肯尼迪和A.C.沃尔用152.4厘米回旋加速器加速的16兆电子伏氘核轰击铀时发现钚238。第二年又发现钚的最重要的同位素钚239。

在自然界中只找到两种钚同位素，一种是从氟碳铈镧矿中找到的微量钚244，它具有足够长的半衰期，可能是地球上原始存在的。另一种是从含铀矿物中找到的钚239，是铀238吸收自然界里的中子而形成的。其他钚同位素都是通过人工核反应合成的。已发现的有质量数232～246的钚同位素。

钚弹爆炸是什么原理

现代原子弹由三个主要部分组成：分别是主级，二次级和辐射容器。主级是一个由钚组成的小球，是炸弹的核心部分。随后这个核心被次要成分包裹，这种次要成分一般是一些化学质，最后在这层质外层用一层铀壳包围。

起爆时中间部分的化学率先被触发，它会引起内爆，产生的爆炸能量可以在瞬间挤压中间的钚芯从而导致钚芯的密度瞬间增加，这种人为迫使原子叠加在一起产生自由的中子，从而引发钚原子核在链式反应中发生裂变从而释放出巨大能量。

这种核弹被形象地称作三位一体，最早的三位一体核弹重约一万磅，现如今科学技术发展已经能将核弹缩减到重250磅，而体积也仅有一个手提箱大小。

钚和毒性

钚具有放射性，但你可能永远也接触不到它。钚虽然存在于自然界中，但是极其微量，大储量高纯度的钚没有天然来源，它必须是通过人造才能产出，但假如人们接触或者吸入了它时，这些钚会困在人们的肺部，并会迅速转移到身体的骨骼和脏器中，并最终导致中毒死亡。钚是迄今为止人类已知毒性最大的放射性毒药之一。
