It is compulsory that the Masters Degree is taken from Health Sciences or Institute of Science giving education on radiotherapy (courses, thesis, clinical practices on radiotherapy are compulsory).

Medical Physicians are working in the hospitals of Ministry of Health or of Universities and in private hospitals. Their work fields are constituted mainly by the ionized radiation such as radiation oncology, nuclear medicine, and diagnostic radiology. For example, the physicians working in above given fields are named as “Radiology Physician” or “Radiation Physician”. There are also the Medical Physicians working in university clinics and with non – ionized radiation For example, physiologic monitoring of patients, ultrasound ophthalmology and biomedical engineering. The duties and responsibilities of medical physicians are constituted mainly by the below given active work fields:

  • Radiation Oncology
  • Diagnostic Therapy
  • Nuclear Medicine
  • Health Physics and Protection against Radiation
  • Non – Ionized Radiation

Most of the Medical Physicians in Hospitals and Medical Institutes are the Radiation Physicians. Most of these Physicians work in cancer treatment centers and institutions. Their contributions in diagnosis and treatment of cancer have substantial importance. The need for the Physicians working in other branches of medicine has been increasing within the last 20 years.
