(III) Assume a liter of milk typically has an activity of 2000 pCi due to \({ }_{19}^{40} \mathrm{K}\). If a person drinks two glasses  per day, estimate the total effective dose (in  and in rem) received in a year. As a crude model, assume the milk stays in the stomach 12 hr and is then released. Assume also that very roughly 10% of the 1.5 MeV released per decay is absorbed by the body. Compare your result to the normal allowed dose of 100 mrem per year. Make your estimate for  a  adult, and  a  baby.
