Tarix
Plutonium was first produced in 1940 by Glenn T. Seaborg, Edwin M. McMillan, Joseph W. Kennedy and Arthur Wahl.
Plutonium-238 was produced by deuteron bombardment of uranium-238 in the 60-inch cyclotron at the University of California, Berkeley.
The Berkeley team made neptunium-238 which decayed to plutonium-238.

Qo‘llanilish sohalari
The isotope plutonium-239 is a key fissile component in nuclear weapons, due to its ease of fission and availability.
Plutonium-238 has also been used successfully to power artificial heart pacemakers, to reduce the risk of repeated surgery.
Plutonium-238 mixed with beryllium is used to generate neutrons for research purposes.
