Plutonium (IPA: /ËpluËËtÉÊniÉm/) is a radioactive, metallic chemical element. It has the symbol Pu and the atomic number 94. It is the element used in most modern nuclear weapons. The most significant isotope of plutonium is 239Pu, with a half-life of 24,100 years. It can be made from natural uranium and is fissile.
France launched Israel on the nuclear path in the late 1950s by building the Dimona reactor, which is still the source of Israel's plutonium--its main nuclear weapon fuel. The reactor's heavy water, essential to achieve a chain reaction, was supplied by Norway in 1959.
