محاسبه دوز رسیده به گنادها ناشی از برخی رادیوگرافی تشخیصی رایج

Background and Aim: The basic aim in radiography is to scan a clear image from the body organs, but the issue of the patient's protection against the harmful effects of ionizing radiation should never be neglected.The present study aimed at calculating the received drug to the perigonadic areas  during radiography. Materials and Methods: In the current study thermoluminescence dosimeter was used to measure the dose absorbed by the skin.Dap values for each examination and also the patients demographic information such as age, body size, weight; and radiographic setting like mA, time, kVp , and focal spot distance  from thefilm were recorded. Gonadal doses were calculated using PCXMC software (V: 2). Results: Maximum dose received by the testicles in the pelvis AP projection was 0.45 mGy and for the ovaries in abdomen PA it was, 0.306 mGy. Minimum dose received by the testicles and ovaries in lumbar LAT was 0.065 and 0.101, respectively. Conclusion: One of the ways for patients’ gonadal dose reduction is to use appropriate shields for radiosensitive organs such as gonads. Hence,it is recommended to use appropriate shields for testicles because of their high radiosensitivity.
