|There is more information available on this subject at Plutonium on the English Wikipedia.|
Plutonium is a radioactive transuranic element. It is used in nuclear weapons. When stored aboard interstellar spacecraft, the plutonium in nuclear weapons generates a Cherenkov radiation aura upon exiting Slipspace that negates stealth measures, forcing stealth vessels to jettison any nukes aboard if a stealthed slipspace exit is necessary.
