RTS4103 - Radiation therapy science 3 - 2018

This unit focuses on the action of ionising radiation on living things at the cellular level and the resulting effects on organs, tissues and the whole body. Students will gain an in-depth knowledge on the biological effects of ionising and non-ionising radiation, and the mechanisms of repair to biological damage. Students will be able to describe the systemic and total body responses to early/late effects of radiation. Students will undertake a critical review on how the effects of radiation on biological tissue can be utilised in the practice of radiation therapy. Students will acquire an appreciation of the potential hazards present in different radiation therapy procedures, and focus on the principles of dose reduction, while maximising the information produced from a particular dose of ionising or non-ionising radiation. Whilst studying these topics, students will be encouraged to critically reflect, analyse and synthesise relevant information from the literature.

Upon successful completion of this unit, students should be able to:

1. Describe the major bio-effects of ionising and non-ionising radiation and explain the severity and risks associated with these bio-effects;
2. Discuss the known biological effects of ionising and non-ionising radiation on cells and tissues;
3. Calculate the radiation dose, and appraise the current scientific theories relating to the risk associated with radiation dose;
4. Explain the rationale used to determine the most appropriate procedure with regard to biological effects;
5. Describe the modifications to procedural technique, required to maximise the benefit from a particular dose of ionising or non-ionising radiation;
6. Outline the principles of radiation safety, protection and ALARA, and justify the medical use of ionising and non-ionising radiations.
