The only problem is its radio active and that means that when it decays it tends to fall apart. It is of course Plutonium and here to spell it out is Cambridge University's Ian Farnan. Plutonium's ...

This, as he found out, isn’t something you should do lightly, as the one he used ended up containing an interesting mix of radioactive materials, including small amounts of plutonium-239 ...

Beginning in the late 1950s, the U.S. met this challenge by developing nuclear batteries known as radioisotope thermoelectric generators (RTGs) and producing plutonium-238 (Pu-238) as their fuel, ...
