An x-ray technician works 5 days per week, 50 weeks per year. Assume the technician takes an average of eight x-rays per day and receives a dose of 5.0 rem/yr as a result. Estimate the dose in rem per x-ray taken.

Solutions

VerifiedIn this problem, an x-ray technician works $5$ days a week, $50$ weeks a year. In a day, the technician receives $8$ x-rays. The biological dose in a year is $5.0~\mathrm{rem/yr}$. For this part, we estimate the dose in rem per x-ray.

Estimated dose per x-ray received dosage, produced rate $\left(x.p.r\right)$ can be calculated as:

$\begin{align*} \textrm{x.p.r}=8\frac{\textrm{x-ray}}{\textrm{day}}\left(5\frac{\textrm{days}}{\textrm{week}}\right)\left[50\frac{\textrm{weeks}}{\textrm{year}}\right]=2\times10^{3}\frac{\textrm{x-ray}}{\textrm{year}} \end{align*}$

Thus, solving for the exposure rate per x-ray $E.R=\left(\frac{e.r}{x.p.r}\right)$, we get:

$\begin{align*} E.R=\frac{5\frac{\textrm{rem}}{\textrm{year}}}{2\times10^{3}\frac{\textrm{x-ray}}{\textrm{year}}} \end{align*}$

Solution is:

$\begin{align*} \boxed{E.R=2.5\times10^{-3}\frac{\textrm{rem}}{\textrm{x-ray}}} \end{align*}$

number of x-rays:

$N = (8) \ (5) \ (50) = 2000$

the exposure rate:

$\dfrac{5 \ rem/yr}{2000 \ x-ray/yr} = 2.5 \times 10^{-3}$ rem/x-ray
