Strontium-90 is one of the most hazardous products of atomic weapons testing because of its long half-life (t1/2 = 28.1 years) and its tendency to accumulate in bone.(a) Write nuclear equations for the decay of 90Sr via the successive emission of two electrons (beta particles).(b) The atomic mass of 90Sr is 89.9073 u and that of 90Zr is 89.9043 u. Calculate the energy released per 90Sr atom, in MeV, in decaying to 90Zr.(c) What will be the initial activity of 1.00 g of 90Sr released into the environment, in disintegrations per second?(d) What activity will the material from part (c) show after 100 years?
