Strantium 90 is a major component of the detonation of nuclear explosives, it is particularly dangerous because it chemically mimics calcium and is therefore incorporated into bone in living beings. It has a half life of 28.1 years. a. Determine the decay constant for Sr-90 6 b. What fraction of the element remains after ten half lives have passed? How many years are required for 99.9% of a sample of Sr-90 to decay?
