A 65-kg person is accidentally exposed for 240 s to a 15-mCi source of beta radiation coming
Question:
(a) What is the activity of the radiation source in disintegrations per second? In becquerels?
(b) Each beta particle has an energy of 8.75 × 10-14, and 7.5% of the radiation is absorbed by the person. Assuming that the absorbed radiation is spread over the person's entire body, calculate the absorbed dose in rads and in grays.
(c) If the RBE of the beta particles is 1.0, what is the effective dose in mrem and in sieverts?
(d) How does the magnitude of this dose of radiation compare with that of a mammogram (300 mrem)?
