The equation for the alpha decay of 238Pu is:94238Pu --> 92234U + 24He representing the alpha particle as a helium Pu-238's emissions consist of alpha particles. In the context of Pu-238 emissions, alpha particles do not harm human tissue, as they do not penetrate outer layers of skin cells. [3] (Some alpha particles, such as those present in cosmic rays, possess enough energy to … Alpha Decay. In alpha decay, a \(\ce{^4He}\) nucleus simply breaks away from the parent nucleus, leaving a daughter with two fewer protons and two fewer neutrons than the parent (Figure \(\PageIndex{2}\)).

The general technique is also laborious, involving chemical preparation of samples in virtually all cases. Pu-238 decays 100% by alpha transitions to U-234. Most of the alpha decay populates the U-234 ground state (71.04 %) and the U-234 ﬁrst excited level with energy of 43.50 keV (28.85 %). Branching of Pu-238 decay by spontaneous ﬁssion is 1.85 (5)E-7 %.
