Success Criteria Grade E Grade C Grade A Recall that only beta and gamma rays can pass through skin Explain why beta and gamma emitters can be used as tracers Explain how radioactive sources are used as tracers in medicine Describe the role of a radiographer Understand why medical tracers should not remain in the body for long periods Explain how radioactive sources are used to treat cancer Key Words: diagnosis • sterilisation • tracer • radiotherapy • radiographer • emitter • X-rays • gamma • beta

Produce a presentation which informs the reader of the uses of nuclear radiation. In particular, you are to include the following: How gamma radiation is used in the diagnosis and treatment of cancer How gamma radiation is used more generally in hospitals What radiography is How radioactive tracers are used and administered in medicine Examples of uses of specific radioactive substances e.g. Iodine-123, Technetium-99m and Cobalt 60 Higher A comparison of the use of gamma rays and X-rays as tracers What a gamma camera is
