The Amount of Receiving Radiation of Radiology Staffs in Imam RezaHospital of Kermanshah (Iran)

摘要

The development of science and technology with the use of radioactive sources for medical, industrial, agricultural and military research purposes has increased the risk of radiation receiving to workers and the general public. The use of ionizing radiation in medicine for diagnosis, treatment and research is an inevitable matter. The purpose of this study was examining the amount of receiving radiation of radiology staffs in Imam Reza Hospital of Kermanshah. The study was a cross-sectional study that aims to measure the amount of receiving radiation of radiology staffs in Imam Reza Hospital of Kermanshah in 2013. The instrument used in this study was geiger-muller counter of gamma-scout-model made in Germany. This device has a digital display and show the receiving dose based on micro sievert per hour. The results of this study showed that in none of unites, the receiving radiation didn?t exceed the threshold. Also the maximum receiving dose is related to the nuclear medicine which was at the time of radiopharmaceutical discharge and minimum receiving dose relates to radiology unit in the unit that simple photos was taken. The highest amount of radiation in the radiology unite is related to X-ray fluoroscopic image with 0/55 micro Sv per hour and the lowest amount relates to simple photo with 0.06 micro Sv per hour. Receiving radiation's amount at the location of staff in CT was 636, Crushers was 396 and nuclear medicine was 360 micro Sv per year. Overall, results of the study showed that none of the investigated units, the receiving radiation was not exceeded the threshold. The staff's receiving dose at this medical center was at standard level. So, it is necessary to accomplishsafety workshop and radiation protection in order to more regardthe safety considerations at the radiography unites.
