WebHalf-life depends on probability because the atoms decay at a random time. Half-life is the expected time when half the number of atoms have decayed, on average. Radioactive … Web22 May 2015 · The biological half-life cannot be determined as precisely as the physical half-life, and the dominance of either rate differs from one radionuclide to another. For many long-lived nuclides, such as 3 H, 14 C, 22 Na, 36 Cl, 60 Co, 137 Cs and 235 U, the much shorter biological half-life (10–70 d) is dominant [ 34 ].
