-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
