Question

A gamma scan showing the active volume of a patient's lungs can be created by having a patient breathe the radioactive isotope 133Xe, which undergoes beta-minus decay with a subsequent gamma emission from the daughter nucleus. A typical procedure gives a dose of 0.30 rem to the lungs. How much energy is deposited in the 1.2 kg mass of a patient's lungs?
