This unit will cover the biological effects of ionizing and non-ionising radiation on cells & tissues; mechanisms of repair to biological damage, systemic & total body responses to early/late effects of radiation, hereditary effects and effects on the embryo & foetus; principles of dose reduction and the relative potential hazards present in different procedures; estimation of risk assessment using accepted theories of dose vs. response; modifications to procedural techniques to maximise the information produced from a particular dose of ionising or non-ionising radiation.


On successful completion of this unit students will 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. Describe the known biological effects of ionising and non-ionising radiation on cells and tissues;
  3. Calculate the radiation dose in a variety of medical radiation scenarios;
  4. Appraise the current scientific theories relating to the risk associated with radiation dose;
  5. Explain the principles of radiation safety and protection.
  6. Explain the rationale used to determine the most appropriate procedure with regard to biological effects
  7. Describe the modifications to procedural technique, required to maximise the benefit from a particular dose of ionising or non-ionising radiation: and
  8. Explain the principles of ALARA and justify the medical use of ionising and non-ionising radiations.
