93 Neptunium Np Etsehiwot Mebrat

Neptunium was found in the Berkeley Radiation Laboratory of the University of California, Berkeley where the group of people created the neptunium isotope 239Np by bombarding uranium with slow motioned neutrons. stable isotopes: 1) 237 Np - it's unique difference is that it has a half life of 2.4 million years, and it makes the largest half life for Neptunium. 2) 236 Np - it's unique difference is that it has a half life of 154 thousand years. 3) 235 Np - then this is the shortest one with a half life of 396.1 days. 237 np is the most common radioactive isotope and it decays to lead by fission
