  3. 3. Department of Medical Physics, McGill University Health Centre Medical Physics Unit, McGill University Montréal, Québec, Canada The residency program is of 2-years duration and provides the resident with clinical experience and theoretical knowledge in all aspects of modern radiation oncology physics. An important objective of the program is to prepare the resident for the professional examination and licensure process in the specialty of Radiation Oncology Physics. The residency program consists of four rotations and four didactic courses. Minimum requirement for admission is M.Sc. degree in Medical Physics; however, the preferred candidate will have a M.Sc. or Ph.D. degree in Medical Physics from a CAMPEP-accredited educational program in Medical Physics. Remuneration is comparable to that received by Post-Doctoral Fellows at McGill University. The four rotations are as follows: (1) Basic Treatment Planning and Standard Treatment Techniques (2) Advanced Treatment Planning and Special Treatment Techniques (3) Quality Assurance and Radiation Protection (4) Clinical Physics Practice and Clinical Physics Project Each rotation is followed by a comprehensive examination. The four didactic courses are as follows: (1) Radiation Physics (MDPH-601) (2) Applied Dosimetry (MDPH-602) (3) Radiation Biology (MDPH-609) (4) Health Physics and Radiation Protection (MDPH-613) A resident who already completed a particular course during graduate studies may obtain a course exemption. 3

  28. 28. Medical Physics Resident and Radiation Oncology Resident Pairing Program Summary Each radiation oncology physics resident will be paired with a radiation oncology medical resident for a one-year term based on calendar year, in order to achieve the aims below. Aims 1. To provide radiation oncology physics residents with a clinical resource person they can consult on matters pertaining to radiation oncology knowledge. 2. To provide radiation oncology medical residents with a physics resource person they can consult on matters pertaining to medical physics knowledge. 3. To foster an exchange between the two groups of residents in terms of both clinical and physics knowledge as well as promote research interests common to both groups. Components 1. Radiation oncology physics residents will be paired with a radiation oncology medical resident prior to the beginning of the calendar year, as determined jointly by the radiation oncology physics residency clinical coordinator and the radiation oncology residency coordinator. 2. Each radiation oncology physics resident/radiation oncology medical resident pair will be required to collaborate on a research or literature review project. 3. Each radiation oncology physics resident/radiation oncology medical resident pair must present on their project at both radiation oncology and medical physics rounds. 4. The radiation oncology resident should assist the physics resident in the preparation of the clinical teaching sessions for which the latter is responsible, and be present for the session. 5. The medical physics resident should assist the radiation oncology resident in the preparation of physics teaching sessions for which the latter is responsible, and be present for the session. 28
  29. 29. Radiation Safety for Radiation Oncology Physics Residents The Radiation Oncology Department of the McGill University Health Centre (MUHC) is licensed by the Canadian Nuclear Safety Commission (CNSC) to use Class II Prescribed Equipment and radioactive material in its facilities. MUHC is committed to the achievement of compliance in accordance with the relevant CNSC regulations and license conditions. Furthermore, the MUHC is committed to ensure that: a) Radiation doses to all staff and the public during routine use of radioactive materials and Class II Prescribed Equipment and in the event of an emergency remain As Low As Reasonably Achievable (ALARA). b) A high standard of radiological safety is maintained at all times in the work environment. c) All relevant laws and regulations with respect to the use of licensed materials and activities related to license conditions are respected. The ultimate responsibility for radiation safety lies with the Chief Executive Officer of the MUHC. This responsibility is exercised in three ways: First, the responsibility for safety is delegated to those managers who are responsible for work involving radioactive materials or equipment that generates ionizing radiation. Managers are responsible for ensuring that all work conducted is in accordance with the relevant CNSC license and MUHC procedures. Responsibility for safety also rests with each individual working with radioactive materials or radiation generating equipment. Second, the Radiation Safety Officer for the MUHC Radiation Oncology and Medical Physics departments as well as all Class II equipment installed in the MUHC (RSO/Class II) is delegated by and reports directly to the Director of Medical Physics to advise him on the status of radiation safety issues, including standards of compliance with current regulations and license conditions. The RSO/Class II also maintains a link with the MUHC Director of Quality and Risk Management for administration of matters with regard to radiation safety in the MUHC. The RSO/Class II is a Canadian College of Physicists in Medicine (CCPM) certified physicist who is directly involved with the clinical, administrative, research and teaching activities of the Departments of Radiation Oncology and Medical Physics. Third, the radiation safety at the MUHC is overseen by the MUHC Radiation Safety Committee (RSC). The radiation safety committee is composed of responsible managers and relevant parties, and reports to the Chief Executive Officer of the MUHC. Terms of Reference of the MUHC Radiation Safety Committee (RSC): Accountability of the RSC The Radiation safety Committee reports to the Chief Executive Officer of the MUHC. Responsibilities of the RSC The responsibilities of the Radiation Safety Committee are as follows: a) To provide overall co-ordination of the MUHC radiation safety program for all MUHC hospital sites and research institutes. 29
