Question 8

A hospital uses a gamma-emitting isotope for cancer treatment. Which property of gamma rays makes them suitable for this application?

Accepted Answer

Their high penetrating power allows them to reach tumors deep inside the body.

Question 9

Which of the following nuclear equations correctly represents gamma emission?

Accepted Answer
