| Abstract | ||
| Positron emission tomography (PET) combined with computed tomography (CT) has been playing key role in important clinical decision-making in many areas ever since its inception in the field of medical imaging. Most of the hospitals are enthusiastic for including PET/CT in their imaging services because of its increasing application particularly in oncology. However, the occupational workers are apprehensive about the risk of higher radiation exposure in a PET/CT facility even more than that in conventional nuclear medicine Gamma camera. There is a need therefore to make the staff aware of the radiation doses they may likely get while working using this facility. We have estimated the radiation exposure to the physicians & technologists working in our PET/CT facility based on the dose rate measurement with regularly calibrated pocket dosimeter and thermo-luminescent detector (TLD); for cumulative dose confirmation. The mean dose measured at the chest level per PET/CT procedure was 4 μSv and 4.75μSv for the physicians and technologists respectively. The mean dose to the physicians per MBq of 18F-FDG injected was 10 nSv/MBq and 35 nSv/MBq at the chest and wrist levels respectively; whereas it was 12 and 25 nSv/MBq for technicians respectively | ||
