Question

As part of a treatment program, a patient ingests a radioactive pharmaceutical containing (32/15)P, which emits beta rays with an RBE of 1.50. The half-life of (32/15)P is 14.28 d, and the initial activity of the medication is 1.34 MBq.

Part A: How many electrons are emitted over the period of 8.00 d?
ne=____

Part B: If the beta rays have an energy of 705 keV, what is the total amount of energy absorbed by the patient's body in 8.00 d? Answer in Joules.
E=____J

Part C: Find the absorbed dosage in rem, assuming the radiation is absorbed by 130 g of tissue.
Dose in rem=_____rem
