The radioactive nuclei 60Co is widely used in medical applications. It undergoes beta decay, and the total energy of the decay process is 2.82 MeV per decay event. The half-life of this nucleus is 272 days. Suppose that a patient is given a dose of 6.9 i of 60 Co. If all of this material decayed while in the patient's body, what would be the total energy deposited there? (1 Ci = 3.70 1010 decays/s)
