11. A 60 kg person accidentally ingests a small source of alpha particles (RBE=15). Theactivity of the source is 0.04 Ci, the half life of the source is 110 years, and each alpha particleemitted has an energy of 0.586MEV. It takes 12 hours for the alpha source to pass through thepersons digestive system and exit the body. (a) How many alpha particles are absorbed by the person(you may assume that 100% of the alpha particles emitted by the source are absorbed by the person)?(b) How much energy is deposited in the person by the source (in J)? (c) What is the absorbed dose(in rad)? (d) What is the absorbed dose (in rem)?

(a) Number of particles absorbed is equal to the number of particles decayed
