caged plutonium which is a transuranic material that has a half-life of 24,065 years, making it decay (into different elements) inside a zinc-aluminum
hull (the aluminum delicates due to the radiation and thus might crumble depending on the
weight of plutonium-239) but doesn't
rust as easily due to the zinc coating
"Our
team have created a simulation of the
half-life decay of plutonium-239 in a
zinc-aluminum material lined caging scenario."
