The knowledge of the radiation dose received by the patient during the radiological examination is essential to\nprevent risks of exposures. The aim of this work is to study patient doses for common diagnostic radiographic\nexaminations in hospitals affiliated to Kashan University of Medical sciences, Iran. The results of this survey are\ncompared with those published by some national and international values. Entrance surface dose (ESD) was\nmeasured based on the exposure parameters used for the actual examination and effective dose (ED) was\ncalculated by use of conversion coefficients calculated by Monte Carlo methods. The mean entrance surface dose\nand effective dose for examinations of the chest (PA, Lat), abdomen (AP), pelvis (AP), lumbar spine (AP, Lat)\nand skull (AP, Lat) are 0.37, 0.99, 2.01, 1.76, 2.18, 5.36, 1.39 and 1.01 mGy, and 0.04, 0.1, 0.28, 0,28, 0.23, 0.13,\n0.01 and 0.01 mSv, respectively. The ESDs and EDs reported in this study, except for examinations of the chest,\nare generally lower than comparable reference dose values published in the literature. On the basis of the results\nobtained in this study can conclude that use of newer equipment and use of the proper radiological parameter can\nsignificantly reduce the absorbed dose. It is recommended that radiological parameter in chest examinations be\nrevised.
