The study is aimed to measure the ambient radiation dose and to estimate the risk level in the nuclear medicine department and estimate the radiation occupational exposure. The study was conducted at Alneelain Diagnostic Center, Khartoum period four months. The radiation doses were measured at different locations using a survey meter. These locations were selected around the nuclear medicine department, include patient waiting room, injection room, storage of injection, hot lab and also around the patient within scan procedure (Bone scan, Thyroid scan, and Renal scan). The maximum ambient dose equivalent rate equal to about 0.5mSv/hr was obtained inside the waste bin. Sites with minimum doses are the gamma camera room and injection room, having ambient dose equivalent rates equal to about 0.01mSv/hr. The result showed that the radiation dose levels at this department does not exceed the recommended dose limits for workers 20mSv/y, that set by Basic Safety Standards which published by the International Atomic Energy agency (IAEA). Also it complies with the national regulation “regulation on basic radiation protection requirement and dose limits 1996” issued by Sudan Atomic Energy Commission act1996. The results do not exceed the values obtained in previous studies. However variations were observed in dose values among previous studies could be due to the differences in exposure parameters and radio isotope used.
