WebbLet’s calculate the half-life of an element by assuming a few things for the sake of calculations. Suppose the original amount of a radioactive element is: N (0) = 200 g. Now let’s assume the final quantity of that element is: N (t) = 50 g. If it took 120 seconds to decay from 3 kg to 1 kg, the time elapsed would be: t = 120 seconds Webb22 jan. 2008 · The Nobel Prize in Physics 1903 was divided, one half awarded to Antoine Henri Becquerel "in recognition of the extraordinary services he has rendered by his discovery of spontaneous radioactivity", the other half jointly to Pierre Curie and Marie Curie, née Sklodowska "in recognition of the extraordinary services they have rendered … great lakes mineral houghton mi
