Option 2.7: How is radiation used to maintain human health?

In this option, students use concepts of nuclear physics to explore how the use of electromagnetic radiation and particle radiation are applied in medical diagnosis and treatment. They learn about the production and simple interpretation of images of the human body produced by a variety of imaging techniques used to observe or monitor the functioning of the human body.

On completion of this unit, the student should be able to use nuclear physics concepts to describe and analyse applications of electromagnetic radiation and particle radiation in medical diagnosis and treatment.

Radiation and the human body

Radioisotopes in medicine
Radioisotopes are extensively used in nuclear medicine to allow physicians to explore bodily structures and functions in vivo (in the living body) with a minimum of invasion to the patient. Radioisotopes are also used in radiotherapy (radiation therapy) to treat some cancers and other medical conditions that require destruction of harmful cells.

The use of radiation in diagnosis and treatment of human illness and disease

Problems with ionising radiation
Radioactivity has many uses but it can also cause problems. Ionising radiation can cause significant problems with damage to cell structures. Nuclear waste has also been a concern to scientists.
