Evaluation of Leakage Dose from Radiology Rooms in Tehran University of Medical Sciences Hospitals
This descriptive cross-sectional study aims to determine the leakage dose from radiology departments in selected hospitals affiliated with Tehran University of Medical Sciences, as well as dosimetry in other related hospital sections.
The study was conducted as a descriptive cross-sectional research to determine the leakage dose from the radiology departments of selected hospitals affiliated with Tehran University of Medical Sciences, as well as to perform dosimetry in other related sections.
In this research, various radiology facilities, including X-ray rooms, CT scans, fluoroscopy, and angiography (covering both supervised and controlled areas), were evaluated to measure leakage doses. Additionally, selected sections such as ICU and NICU were studied to assess the doses received by patient companions, other patients present in the room, and non-radiation staff.
The dosimeter used for measuring leakage doses was a CFP SCINTILLOMETER model SCINT-2215 scintillator detector, which has a measurement accuracy of ±3% and a dose range of 0.01 to 100 microsieverts per hour for X-rays and gamma rays.
For assessing the doses received by patient companions, other patients, and non-radiation staff, a Thermoluminescence Detector (TLD) GR200 was utilized. Additionally, to evaluate radiation doses in other related hospital sections, 25 TLD badges were installed for two months across five departments of the Children's Medical Center Hospital, and the recorded dose values were read.
The measured dose values were subsequently analyzed using SPSS software.
