| DESCRIPTION | This study unit focuses on preparing candidates to fulfill their role as Medical Physicists and as potential Medical Physics Experts, Radiation Protection Experts (Medical) and Radiation Protection Officers (Medical) in Radiation Oncology. Study-unit Aims The study-unit will help students acquire the necessary knowledge and skills to be able to contribute to maintaining and improving the quality, safety and cost-effectiveness of healthcare services through patient-oriented activities requiring expert action, involvement or advice regarding the specification, selection, acceptance testing, commissioning, quality assurance including quality control, and optimised clinical use of the medical devices used in Radiation Oncology and regarding risks from associated ionising radiation. The scope includes risks to volunteers in biomedical research, workers and public (when associated with patient safety and including carers and comforters). The study-unit will include both beam therapy and brachytherapy.
