WebbThe answer can be found by examining Figure 1, which shows how the number of radioactive nuclei in a sample decreases with time. The time in which half of the original number of nuclei decay is defined as the half-life, t1/2. Half of the remaining nuclei decay in the next half-life. Further, half of that amount decays in the following half-life. Webb20 maj 2024 · The radioactivity of a sample is R1 at a time T1 and R2 at a time T2 .
