- treat cancer
2
Q
Examples of uses of radiation in medicine include:
A
- radioactive tracers
- gamma cameras
- radiation therapy
3
Q

These can detect blockages and leaks, for example, in the kidney. The patient intakes water containing a small amount of radioactive isotope which makes the reading increase and the radioisotope can’t be excreted.
4
Q
Gamma Cameras - what is it?
A
A radioactive isotope of technetium is consumed by a patient which emits gamma radiation causing a detector to produce an image to map the functions of the body.
