Increasing concern has recently been expressed in the literature that the referring doctor's knowledge of radiation doses incurred during radiological procedures is inadequate. Such information may be particularly relevant when the expansion of imaging technology is considered. Hence the objective of this work is to assess the awareness of physicians about radiation dose and hazards of radiation. The study was performed among medical doctors at Tikur Anbessa Specialized Referral Teaching Hospital, the largest medical school in the country. A 135 self administered questionnaire was circulated randomly from a range of specialties; out of which 114 questionnaires were completed and used in the study giving a response rate of 85%. Participants were asked about the radiation dose from a chest radiograph, the annual dose from background radiation, and cancer risk from several common radiological procedures. A mean score of 7.1 out of 19 was achieved. 12 doctors had received formal training about ionizing radiation, and these participants scored higher than those with no previous training in this area. Our survey suggested that clinicians' awareness of radiation doses imparted during common radiological procedures, and the consequent risk to the individual patient is poor. A major curriculum revision of both undergraduate and graduate medical education regarding awareness on radiation is mandatory to improve this deficiency.
