It's Elemental The Element Uranium

To produce plutonium 239, atoms of uranium 238 are exposed to neutrons. Uranium 239 forms when uranium 238 absorbs a neutron. Uranium 239 has a half life of about 23 minutes and decays into neptunium 239 through beta decay. Neptunium 239 has a half life of about 2.4 days and decays into plutonium 239, also through beta decay.
