Naturally occurring 40 K is listed as responsible for 16 mrem/y of background radiation. Calculate the mass

Question:

Naturally occurring ⁴⁰K is listed as responsible for 16 mrem/y of background radiation. Calculate the mass of ⁴⁰K that must be inside the 55-kg body of a woman to produce this dose. Each ⁴⁰K decay emits a 1.32-MeV β, and 50% of the energy is absorbed inside the body.
