A 75 kg patient is given a bone scan. A phosphorus compound containing the gamma-emitter 99Tc is injected into the patient. It is taken up by the bones, and the emitted gamma rays are measured. The procedure exposes the patient to 3.6 mSv (360 mrem) of radiation. What is the total energy deposited in the patient’s body, in J and in eV?
