WebMar 23, 2024 · Decay Series. The decay of a radioactive nucleus is a move toward becoming stable. Often, a radioactive nucleus cannot reach a stable state through a single decay. In such cases, a series of decays will occur until a stable nucleus is formed. The decay of \(\ce{U}\)-238 is an example of this. Web1μs = 10 -6 s, 1 ms = 10 -3 s,1 My = 10 6 y, 1 Gy = 10 9 y.
