Large amounts of 65zn are produced in copper exposed to accelerator beams. A physicist was machining a piece of contaminated copper, a physicist ingests 76.4 µCi of 65zn. Each 65zn decay emits an average y-ray energy of 0.550 Mev 44.5% of which is absorbed in the body of the scientist. The mass of the scientist is 71.0-kg. (a) Calculate the activity of the source in becquerels. Bq (b) Calculation the number of decays in one year. (c) Calculate the ionizing energy that is deposited each year in the scientist.
