What is activity of radiation in disintegrations per second

Reference no: EM131026714

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 X 10-13 J. Calculate the absorbed dose in millirads and grays.
