ABSTRACT: This study was carried out to analyze individual annual dose records of diagnostic
radiology staff at forty-eight (48) different medical facilities in urban
and rural Region of Ghana for the period of 2011-2015. The monitored dose
data were extracted from the Radiation Protection Institute of the Ghana
Atomic Energy Commission’s database called the Dose Management System
(DMS). The doses of these OEWs analyzed, are divided into four subgroups
namely; general radiographers, radiologists, computed tomography (CT)
technologists, fluoroscopy technologists. The dose distribution, collective
dose and mean annual dose were determined. A total of 1574 OEWs were
monitored comprising of 56% radiographers, 15% radiologist, 21% computed
tomography (CT) technologists and 8% fluoroscopy technologists. The average
annual effective dose ranged from 0.36 to 1.70 mSv with radiographers
receiving the largest. Fluoroscopy technologist recorded the least annual total
collective effective dose value of 0.1 person-Sv. The study contributes to the
existing works to promote a more comprehensive personal monitoring service
for OEWs. Continued analysis of occupational doses should be an
integral component of institutional radiation safety programs in Ghana.
