Web12 de set. de 2024 · N = N0 2n. If the decay constant (λ) is large, the half-life is small, and vice versa. To determine the relationship between these quantities, note that when t = T1 / 2, then N = N0 / 2. Thus, Equation 10.4.4 can be rewritten as. N0 2 = N0e − λT1 / 2. Dividing both sides by N0 and taking the natural logarithm yields. Web11 de abr. de 2024 · Radioactivity can be measured in a variety of ways, but the most common unit of measurement is the becquerel (Bq), which is named after the French physicist Henri Becquerel, who discovered radioactivity in 1896. We can define becquerel as the activity of a quantity of radioactive material in which one nucleus decays per second.
