For a gamma scan of a liver, a patient ingests a 15 MBq sample of 99Tc*. It decays with a 6.0 hour half-life and emits a 0.14 MeV gamma ray (RBE= 1) each decay. Approximately 55 % of the radioactive material remains in the liver. If all the atoms of 99Tc* decay in the patient's 1300 g liver, determine the total equivalent dose received by the patient's liver. OA. 8.06 Sv B. 8.06 mSv OC. 4.43 mSv D.3.07 mSv

Transcribed Image Text:What decay mode and daughter nucleus are expected for 35p?
OA. We expect the 35p to decay by beta-plus. The daughter nucleus is 35 Ar.
B. We expect the 35p to decay by beta-minus. The daughter nucleus is 35 Cl.
OC. We expect the 35p to decay by beta-plus. The daughter nucleus is 35 Al.
OD. We expect the 35p to decay by beta-minus. The daughter nucleus is 35s.
