fa بررسی میزان دوز تشعشعی دریافتی کارکنان اتاق عمل از آزمون‌های رادیولوژیک در حین اعمال جراحی مقاله پژوهشی Original Research Article <p style="text-align: justify;"><strong><em>Background and Objective: </em></strong>Utilization of ionizing radiation in some <a name="OLE_LINK20"></a><a name="OLE_LINK19">surgery operations </a>(especially orthopedic operations) is inevitable.&nbsp; One of the main occupational hazards of physicians and other personnel could be radiation exposure risks. This study aimed to evaluate the exposure doses received by operating room personnel in such surgery operations<strong>. </strong><br> <strong><em>Materials and Methods:</em></strong> 30 personnel of operation room in university affiliated hospitals of Hamadan city (excluding physicians and nurses) were studied as they received radiation doses.&nbsp; 3 TLD (<em>thermoluminescent dosimet</em>ers) chips were fixed on the apron of each <a name="OLE_LINK22"></a><a name="OLE_LINK21">staff member</a>. To estimate the high risk examinations, staff members also completed a questionnaire about the type and number of the radiological examinations that they had participated.&nbsp;<br> <strong><em>Results: </em></strong>Minimum and maximum level of doses received by the participants were between 0.24 and 0.56 mSv in a four month period. Therefore, amount of annual doses received by the personnel would be between 0.73 and 1.7 mSv, respectively (without reduction of background radiation). As the accuracy of TL dosimeters is normally about 0.1 mSv; therefore, it can be claimed that the received doses by the personnel was very low and comparable with background radiation.&nbsp;&nbsp;<br> <strong><em>Conclusion: </em></strong>The results indicated that the radiation doses received by operating room personnel &nbsp;were &nbsp;very low. They were less than maximum predicted doses reported by the International Commission of Radiation Protection. However, the use of dose recording systems for awareness about absorbed doses beyond permitted limits is necessary.&nbsp;</p> Operating room personnel, Radiation dose, Radiological examinations, thermoluminescent dosimeters (TLD) 86 95 http://journal.zums.ac.ir/browse.php?a_code=A-10-4-571&slc_lang=fa&sid=1 Ali Heydari علی حیدری 5200319475328460060200 5200319475328460060200 No Dept. of Operating Room, Hamadan University of Medical Sciences, Hamadan, Iran کارشناس ارشد بیهوشی، عضو هیات علمی دانشگاه علوم پزشکی همدان Karim Ghazi-khanlou Sani کریم قاضی خانلو‌ثانی ghazi@umsha.ac.ir 5200319475328460060201 5200319475328460060201 Yes Dept. of Radiology, Hamadan University of Medical Sciences, Hamadan, Iran کارشناس ارشد فیزیک پزشکی، عضو هیات علمی دانشگاه علوم پزشکی همدان Iraj Salehi ایرج صالحی 5200319475328460060202 5200319475328460060202 No Dept. of Anesthesia, Hamadan University of Medical Sciences, Hamadan, Iran دکترای فیزیولوژی، استادیار دانشگاه علوم پزشکی همدان Ali Akbar sharefi علی اکبر شرفی 5200319475328460060203 5200319475328460060203 No Dept. of Radiology Tehran University of Medical Sciences, Tehran, Iran دکترای فیزیک پزشکی، استاد دانشگاه علوم پزشکی تهران Nima Rostampour نیما رستم پور 5200319475328460060204 5200319475328460060204 No Dept. of Medical Physics, Hamadan University of Medical Sciences, Hamadan, Iran کارشناس ارشد فیزیک پزشکی، عضو هیات علمی دانشگاه علوم پزشکی همدان
