【辟谣？】钚的毒性，没那么可怕。

小日本的3号堆爆了。里面有U，有Pu，大概都出来了。
有传言，Pu是世界上最毒的物质。5克Pu能毒死全世界的人。
但是呢？
根据危机百科的记载，
粗翻译。

按照危机百科上的解释，Pu的毒性在于放射性。它的本身化学毒性远远不及砷（As）和氰化物(CN-)，和咖啡因差不多。

Isotopes and compounds of plutonium are dangerous due to their radioactivity. Contamination by plutonium oxide (spontaneously oxidized plutonium) has resulted from a number of military nuclear accidents where nuclear weapons have burned.[85] Based on chemical toxicity alone, the element is less dangerous than arsenic or cyanide and about the same as caffeine.[86][87]

Pu进入人体后会沉降与骨骼和肝。它吸收的量不多，但是也很难排出。

The alpha radiation plutonium emits does not penetrate the skin but can irradiate internal organs when plutonium is inhaled or ingested.[32] The skeleton, where plutonium is absorbed by the bone surface, and the liver, where it collects and becomes concentrated, are at risk.[31] Plutonium is not absorbed into the body efficiently when ingested; only 0.04% of plutonium oxide is absorbed after ingestion.[32] What plutonium is absorbed into the body is excreted very slowly, with a biological half-life of 200 years.[88] Plutonium passes only slowly through cell membranes and intestinal boundaries, so absorption by ingestion and incorporation into bone structure proceeds very slowly.[89][90]

吸入Pu是很可怕的事情。达到400mSv的放射性就能让人得肺癌的机会大大增加。5000个含Pu气溶胶颗粒就能让你肺癌的几率比美国标准高1%。大量吸入免不了要挂的。但是还没有人直接死于Pu吸入这样的案例。

Plutonium is more dangerous when inhaled than when ingested. The risk of lung cancer increases once the total dose equivalent of inhaled radiation exceeds 400 mSv.[91] The U.S. Department of Energy estimates that the lifetime cancer risk for inhaling 5,000 plutonium particles, each about 3 microns wide, to be 1% over the background U.S. average.[92] Ingestion or inhalation of large amounts may cause acute radiation poisoning and death; no human is known to have died because of inhaling or ingesting plutonium, and many people have measurable amounts of plutonium in their bodies.[87]

总之就是说呢，Pu并没有人们想象的可怕，因为40年代在美国洛斯阿拉莫斯进行试验的25名科学家吸入的Pu能让他们的肺癌可能性增加到99.5%，但是他们最后都不是死于肺癌。
These studies generally do not show especially high plutonium toxicity or plutonium-induced cancer results.[89] "There were about 25 workers from Los Alamos National Laboratory who inhaled a considerable amount of plutonium dust during the 1940's; according to the hot-particle theory, each of them has a 99.5% chance of being dead from lung cancer by now, but there has not been a single lung cancer among them."[93][94]

最后，喜感的结尾：Pu尝起来像金属。
Plutonium has a metallic taste.[95]


Pu是这样的。

这块Pu能做成一个原子弹！！

这是Pu各种价态的溶液。
