Radiologic dosimetry and safety

Objectives On successful completion of this subject students will understand the fundamental concepts of radiologic dosimetry and be able to calculate dose and equivalent dose for x-rays as they interact with living tissue. Students will also have a knowledge of the determinants of the biological effects of radiation and their classification, the interaction of radiation with living tissue, personal and clinical laboratory dose monitoring equipment and be able to measure, record and report radiation doses in accordance with the requirements of the statutory regulations in force.
