Evaluation of X-ray equivalent dose measurement in the radiology department of state and semi-governmental centers of Sistan and Baluchestan province (1397)

Background and Aim : Radiation from natural rays such as cosmic and radio beams such as radiofrequency can cause harmful effects on humans and other living organisms. This study was designed to measure the relative distribution of the particle size distribution in the waiting room Radiology of public and semi-governmental centers in Sistan and Baluchestan province (1397).Methods : This descriptive-analytic study was conducted on waiting rooms of 20 sections of Radiography and CTscan in governmental and semi-governmental centers of the province in 1397. Selectable samples were easy and affordable. A dosimeter has been used to study the Gayer Müller dosimeter of the American company LND712, an alpha, beta, gamma and X-ray diagnostic measurement system. The dose rate was in the range of 0.0001 to 1100 microsurts per hour and with a precision of 10% ± 15% and an equivalent dose rate in mSv. Dosimeters were performed at different points in the waiting room of the radiological centers, taking into account variables such as the highest Lat lumbar conditions, the dot dosimeters, the start and end of the dose record, the distance from the waiting room, and the control and control. Data were analyzed using SPSS software and Kruskal-Wallis test and t-test Independent..Results : : Imam Khomeini Khash Hospital with a dose of 3.275 mc / h, doses above the standard level, and Ali Asghar Hospital with a dosage of 0.019 mc / hr had the lowest dose rate (P <0.001). Also, the average of the leakage doses of the back door The CTscan room was 1,935 microsites per hour. (P <0.018) at a distance of one meter from the control room and the waiting room for all of the imaging sections studied, the leakage doses were at the radiation exposure level.Conclusion : The average dose of leakage doses behind the door of the waiting room for radiography compared with CTscan in the province with little difference. This significant difference in the dose rate is related to factors such as the life of the imaging apparatus, the time taken to construct imaging rooms, and the degree of utilization of materials used in the walls of the imaging chambers.
