A cobalt-60 source with activity 2.60×10-4 Ci is embedded in a tumor that has mas 0.20 kg. The source emits gamma photons with average energy 1.25 MeV. Half the photons are absorbed in the tumor, and half escape. i. What energy is delivered to the tumor per second? [4 marks] ii. What absorbed dose, in rad, is delivered per second? [2 marks] iii. What equivalent dose, in rem, is delivered per second if the RBE for these gamma rays is...

After the Fukushima Nuclear reactor disaster, people were evacuated from the affected area, but not all dogs were. People rescued and treated the dogs to help them eliminate radioactive nuclei from their bodies. The main isotope of concern was 137 Cs, which undergoes beta-minus decay with the subsequent emission of a gamma ray. Both the beta and the gamma radiation have RBE=1, and for one decay the total energy deposited in tissue is 1.2 MeV. 137 Cs has a half...
