The activity of a sample which registers 3 × 10 4 disintegrations in five minutes should be calculated. Concept introduction: Activity is defined as the product of rate constant and number of atoms. It is also defined as the rate of decay or expresses number of atoms decays in unit time. The mathematical expression is given by: A = kN Where, A = activity, k = first order rate constant and N = number of radioactive nuclei. Activity can be expressed in following units: 1 Bq = 1 atom/s 1 Ci = 3.700 × 10 10 atoms/s
