Evaluation of radiation protection in some nuclear medicine department

This study was carryout to evaluate the radiation protection in nuclear medicine department in Sudan, accordance with the standards international recommendation and code of practice for radiation protection in nuclear medicine, the evaluation was done for three nuclear medicine departments, included direct measurement of dose rate and the contamination level in some areas, were radiation sources, radiation workers and public are involved. The data was collected and analyzed from the results for three nuclear medicine departments that the average reading of ambient dose rate in : outside the door of imaging room (SPECT) 0.18μSv/h in hospital (1)& and 0.19μSv/h in hospital(2) and 0.19μSv/h hospital(3), inside control of imaging room (SPECT) 27.8μSv/h in hospital(1)& 0.14μSv/h in hospital(2)& 14μSv/h in hospital(3), inside the injection room 28.81μSv/h in hospital(1), 0.36μSv/h in hpspital(2), 0.06μSv/h in hospital(3) outside the door of lap, 0.65μSv/h in hospital(1), 0.13μSv/h in hospital(2) & 0.12μSv/h in hospital(3), inside the hot lap, 9.68μSv/h in hospital(1) & 0.30μSv/h in hospital(2) & 0.85 μSv/h in hospital(3), in outsidee the door of waiting room of injected patient 1.41μSv/h in hospital(1)& 0.16μSv/h in hospital(2) & 1.08μSv/h in hospital(3). Avaerge reading of contamination in: Floor of hot lap 44.50 B/cm² hospital(1) & 4.42B/cm²in hospital(2) & 6.22 B/cm² in hospital (3) . on the bench tap 186.30 B/cm² hospital(1), 19.91 B/cm² in hospital(2) & 8.77B/cm² in hospital(3) floor of injection room 12.60 B/cm² in hospital(1) & 11.70 B/cm² in hospital(2) & 13.73 B/cm² hospital(3) & table of injection room 13.00 B/cm² in hospital(1)& 11.70 B/cm²in hospital(2)& 13.73 B/cm² in hospital & tble of injection room 13.00 B/cm² in hospital(1) & 20.40 B/cm² in hospital(2) & 23.23 B/cm² B/cm² in hospital(3) on the shield of working surface 144.30 B/cm in hospital(1)& 47.00 B/cm² in hospital(2) & 52.33 B/cm² in hospital(3) , and makes check list containing eleven area prepared by the International Atomic Energy Agency (IAEA): this questionnaire has been filled by radiation protection officer (RPO), nuclear medicine technologist nuclear medicine specialist in nuclear medicine department. The data that was collcted and analyzed from the results for three nuclear medicine department from checklist yes percentage (%) 80.2% in hospital(1), 81.6% in hospital(2) 81.6% in hospital(3) and no percentage (%) 19.8% in hospital(1). 18.$% in hospital(2), 18.4% in hospital(3), the level of radiation dose and the contamination level were found within acceptable limits but are not applying a fully safety and radiation protection, and have not appropriate equipment. The governmental hospital at the level protection than the private hospitals. (Author)
