Introduction

A gamma scan showing the active volume of a patient's lungs can be created by having a patient breathe the radioactive isotope $133$Xe$133$Xe$,$ which undergoes beta$-$minus decay with a subsequent gamma emission from the daughter nucleus. A typical procedure gives a dose of $3\mathrm{.}0$ mSvmSv to the lungs.

Part A

How much energy is deposited in the $1\mathrm{.}2$ kgkg mass of a patient's lungs?
