The halflife is 2.1 days. Multiply that by about 5 to get the time to decay to near zero.
10.5 days or so.
Uranium 238 is bombarded by neutrons, and forms Neptunium 238. Neptunium decays to form Plutonium 238.
Uranium 238 is bombarded by neutrons, and forms Neptunium 238. Neptunium decays to form Plutonium 238.
The half life of neptunium-238 is 2,117 days.
For the first preparation of neptunium the nuclear reaction was:U-238 + n --------------- U-239---------------Np-239
