0 a chemical element that is a metal used in the production of nuclear power, and in nuclear weapons -- plutonio
1 a radioactive element used in many nuclear processes (symbol Pu). -- plutonio
However, work is also needed on high temperature reactors, which are notable both for their energy efficiency and for their capacity to eliminate 90 % of military plutonium.
Dozens of tons of waste plutonium have to be destroyed as a result of disarmament negotiations.
Only a few kilograms of separated plutonium are needed to build a crude nuclear explosive device.
That is what the nuclear industry wants because we do not have plutonium.
But even if we abandon nuclear energy, that does not eliminate the existing plutonium.
This means that inhaling a few micrograms of plutonium can cause lung or tongue cancer.
