ABSTRACT
Imaging facilities within the Port Harcourt metropolis are ever on the increase, imaging practitioners are constantly trained and deployed into the work force. An issue constantly facing the imaging and radiology practice is the issue of work safety. Against this background, this study specifically aims at assessing safety measures employed in the design and construction of imaging centres in the Port Harcourt metropolis. A case study design was employed to investigate into 3 imaging facilities within the Port Harcourt metropolis, data was collected using a question and some 15 respondents across the 3 facilities (5 per facility) where sampled. There was 100% response with respect to the completion of data collection instrument. Findings show a relative compliance to radiation safety principles and guidelines, as some guidelines and principles where upheld while others were not. It was recommended that there should be strict supervision of the design and construction of imaging facilities to ensure that NNRA and IAEA guidelines are closely adhered to, also, periodic assessment of workers is encouraged as well as creating awareness on radiation safety guidelines and principles to ensure occupational safety.
