Question
Large amounts of ${}^{65}\textrm{Zn}$ are produced in copper exposed to accelerator beams. While machining contaminated copper, a physicist ingests $50 \textrm{ }\mu\textrm{Ci}$ of ${}^{65}\textrm{Zn}$. Each ${}^{65}\textrm{Zn}$ decay emits an average $\gamma$-ray energy of $0.550 \textrm{ MeV}$, 40.0% of which is absorbed in the scientist's 75.0 kg body. What dose in mSv is caused by this in one day?
$0.0751 \textrm{ mSv/d}$
