Solved: A 65-kg person is accidentally exposed for 240 s
Chapter , Problem 21.70(choose chapter or problem)
A 65-kg person is accidentally exposed for 240 s to a 15-mCi source of beta radiation coming from a sample of 90 Sr. (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 J. and 7.5% of the radiation is absorbed by the person. Assuming that the absorbed radiation is spread over the persons 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) Is the radiation dose equal to, greater than, or less than that for a typical mammogram (300 mrem)?
