11. A 60 kg person accidentally ingests a small source of alpha particles (RBE=15). The activity of the source is 0.04 Ci, the half life of the source is 110 years, and each alpha particle emitted has an energy of 0.586MEV. It takes 12 hours for the alpha source to pass through the persons 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)?
