(1) (A)A cancer patient is exposed to γ rays from a 4800 Ci ⁶⁰Co transillumination unit for 33.0 s. The γ rays are collimated in such a manner that only 1.00% of them strike the patient. Of those, 20.0% are absorbed in a tumor having a mass of 1.20 kg. What is the dose in rem to the tumor, if the average γ energy per decay is 1.25 MeV? None of the β s from the decay reach the patient.

(B) At full energy, protons in the 2.00 km diameter Fermilab synchrotron travel at nearly the speed of light, since their energy is about 1000 times their rest mass energy. How long in seconds does it take for a proton to complete one trip around? How many times per second will it pass through the target area?
