The increasing interest of medical institutes in the development of imaging services to include the hybrid system [Positron Emission Tomography combined with Computed Tomography(PET/CT)], this system is acquiring explosive growth due to its ability to accurately detect and stage many types of cancer and follow the progress of treatments. An increasing demand for use of (18F-FDG PET) in oncology has been the main reason for its growth. The physical characteristics of positron emissions result in higher radiation risk for staff and growing use of PET/CT for diagnostic purposes increase radiation exposure. The objective of this study was to estimate the radiation exposure to the medical physicists, technicians and nurses working in three Egyptian nuclear medicine institutes under our investigations, based on the whole body collective dose measured by thermoluminescent dosimeters (TLDs) and the effective dose per study received by medical staff were measured by electronic pocked dosimeters and the finger doses by ring dosimeter during a period of six months. The (mean± SD) dose measured per PET/CT procedure were (2.45±0.137, 3.22±0.218 and 1.69±0.11) μSv for the medical physicist, technician and nurse respectively. The (mean± SD) dose measured per MBq of 18F-FDG were (7.35±0.43, 9.73±0.66 and 5.13±0.33) nSv/MBq for the medical physicist, technician and nurse respectively. The (mean± SD) finger dose measured per 18F-FDGPET/CT scans were (179.9±24.94, 8.82±2.912 and 24.15±4.164) μSv for the medical physicist, technician and nurse respectively.Downloads
