Consider a patient who swallows a radiopharmaceutical that utilizes phosphorus32 32 15p , a β − emitter with a half-life of 14.3 days. the average kinetic energy of the emitted electrons is 720 kev. if the initial sample contained 1.46 × 1014 atoms, find the number of decays that occur in a 15-day period. answer in units of decays.
find the total energy of the radiation emitted during the 15 days. answer in units of j
find the absorbed dose if the electrons are completely absorbed in the target tissue which has a mass of 92 g. answer in units of gy.
