Question 10

In certain granite-rich areas, the average background radiation dose received by a resident is 6.8 mSv6.8\text{ mSv}6.8 mSv per year.

A single head CT (computed tomography) scan delivers a radiation dose of 1.7 mSv1.7\text{ mSv}1.7 mSv.

Calculate how many head CT scans would deliver a radiation dose equivalent to the total background radiation dose received by a resident in this granite-rich area over a period of 5.0 years.
