On Thursday, police in Japan announced they were prosecuting a man who was caught selling Americium. He bought the material on the internet. But how did he get hold of it so easily?
Americium-241m, the form that was involved, could be used in a nuclear weapon. Americium is not normally the material you think of when talking about nuclear weapons, usually it’s uranium and plutonium. In fact, it has never been used in any nuclear weapons test or is in any current device. However, an Americium weapon is possible.
