A laboratory rat is exposed to an alpha-radiation source whose activity is 14.3 mCi.
(a) What is the activity of the radiation in disintegrations per second? In becquerels?
(b) The rat has a mass of 385 g and is exposed to the radiation for 14.0 s, absorbing 35% of the emitted alpha particles, each having an energy of 9.12 × 10-13. Calculate the absorbed dose in millirads and grays.
(c) If the RBE of the radiation is 9.5, calculate the effective absorbed dose in mrem and Sv.
