Abstract
Objective: The study aimed to assess the level of knowledge about radiation doses in common radiological examinations among residents and interns, compare the level of knowledge about radiation doses in common radiological examinations between residents in different specialties, and compare the level of knowledge about radiation doses in common radiological examinations between residents and interns. Methods: A cross-sectional study was conducted on a sample of 157 Physicians in King Khalid University Hospital and King Fahad Medical City. Using the simple random technique with the help of a questionnaire, the data were processed using SPSS (version 22). Results: Overall, 58.6% of the participants underestimated the radiation dose of common radiologic examinations whereas 28.1% correctly recognized them. Conclusion: The knowledge of radiation doses of common radiological examinations is suboptimal among interns and residents, including those of radiology specialty. They mostly underestimate the radiation dose which may put patients at risk of exposure to unnecessary radiation. Educational courses on radiation protection including radiation dose received by patients and radiation safety are recommended to be held for interns and residents.
