If naturally occurring 40K is responsible for a dose equivalent of 0.16 mSv/y of background radiation, calculate the mass of 40K that must be inside the 59 kg body of a woman to produce this dose. Assume that each 40K decay emits a 1.30 MeV β, and that 40% of this energy is absorbed inside the body. The half life of 40K is 1.25 × 109 years.
