1. The problem statement, all variables and given/known data Alpha particles with an RBE of 13 deliver a 53 mrad whole-body radiation dose to a 65 kg patient. (a) What dosage, in rem, does the patient receive? (b) How much energy is absorbed by the patient (in mJ)? 2. Relevant equations dose in rem = dose in rad x RBE 3. The attempt at a solution I correctly answered part (a), getting 0.689J/kg as my answer. For part (b), I then multipled the answer from (a) by 65kg, which equals 44.785 J, or 44,785 mJ. However, my answer is incorrect. Is there something I am missing? Thanks.
