The four most common modes of radioactive decay are: alpha decay, beta decay, inverse beta decay (considered as both positron emission and electron capture), and isomeric transition. Of these decay processes, only alpha decay changes the atomic mass number (A) of the nucleus, and always decreases it by four. Because of this, almost any decay will result in a nucleus whose atomic mass … Web9 rows · The decay of Uranium 234 to Thorium 230 is part of the much longer decay series begining in 238 U and ending in 206 Pb.
