Evaluation of Patient Radiation Doses in Skull Radiography
Purpose: Exposures to medical ionizing radiations elevate the risk of stochastic effects such as cancer in exposed individuals. It is of utmost importance to monitor the radiation doses delivered to patients and their optimization to reduce the associated radiation risks without limiting the diagnostic information. Methods: Entrance surface air kerma (ESAK) in a total of 64 adult patients in diagnostic digital Xray examinations were calculated and effective doses were estimated as per International Atomic Energy Agency (IAEA). Results: Median ESAK (mGy) and associated effective doses obtained were skull PA (0.45mGy, 0.005mSv) and skull Lat (0.25mGy, 0.003mSv). Results were compared with UK diagnostic reference levels and studies in India.Conclusion: The comparison revealed that the calculated ESAK and effective dose values wereless than the published literature. ESAK values reported in this study could further contribute toestablishing LDRLs.
