Question 20

Radioactive isotopes are widely used in medicine for both medical imaging (diagnosis) and therapy (treatment).

Describe one way a radioactive isotope is used as a medical tracer to diagnose a condition, and one way a radioactive isotope is used in radiotherapy to treat a disease.

In your answer, you should explain how the physical properties (such as half-life and radiation type) of the isotopes make them suitable for each purpose.
