Gamma radiation can damage living cells. Doctors sometimes inject patients with radioactive material which emits gamma radiation, in order to perform a scan. What can we say about this?
The process carries some risk, but these risks are small compared to the benefits of the scan.
What is the voltage of the mains supply in Britain?
