Question:

A patient receives a gamma scan/ of his liver. He ingests 3.7 MBq of \({ }^{198} \mathrm{Au}\), which decays with a 2.7 day half-life by emitting a \(1.4 \mathrm{MeV}\) beta particle. Medical tests show that \(60 \%\) of this isotope is absorbed and retained by the liver. If all of the radioactive decay energy is deposited in the liver, what is the total dose equivalent received by the patient's \(1.5 \mathrm{~kg}\) liver once all of the atoms have decayed?
