Practice Problem 10

Calculate the rems of radiation absorbed by the average person from the 14C in his or her body.  Assume the activity of the 14C in the average body is 0.08 mCi, the energy of the b-particles emitted when 14C decays is 0.156 MeV, and about one-third of this energy is captured by the body.


0.001 rems, or 1 millirem per year.
