An average adult body contains about 0.10Ci of 4019K, which comes from food. (a) How many decays

Question:

An average adult body contains about 0.10μCi of 4019K, which comes from food.

(a) How many decays occur per second?

(b) The potassium decay produces beta particles with energies of around 1.4 MeV. Estimate the dose per year in sieverts for a 65-kg adult. Is this a significant fraction of the 3.6-mSv/yr background rate?
