(c) The isotope phosphorous-32 (32P) is a beta (8-) radioactive decay emitter with a hall- life of 14.5 days. (v) Calculate the energy in units of MeV for the energy released in the decay of one 32 15 P nucleus. (vi) Determine the total energy, in units of MeV, that has been released by the sample in this 3-day period of time.

The isotope 40K can decay to either 40Ca or 40Ar; assume both decays have a half-life of 1.26 X 109 y. The ratio of the Ca produced to the Ar produced is 8.54/1=8.54. A sample originally had only 40K. It now has equal amounts of 40K and 40Ar; that is the ratio of K to Ar is 1/1=1. How old is the sample? (Hint: work this like other radioactive-dating problems, except that this decay has two products).

(Figure 1) shows the decay scheme for 137Cs, which has two possible beta decay modes. The first, labeled β1, is a decay directly to the ground state of 137Ba. The second beta decay (β2) is to an excited state 137Ba∗. This excited state subsequently undergoes gamma decay to the ground state. In beta decay, the maximum possible energy of the emitted beta particle is equal to the difference in energy between the initial and final states of the nucleus. The...
