Medical radiation workers are subject to occupational exposures and differences in workload, area of work and types of exposure can lead to variations in exposures between different occupational groups. We investigated the occupational exposures of 572 workers from four departments in two community hospitals and stratified into 22 occupational groups in order to identify groups with the highest radiation exposure. The occupational doses from 2015 to 2019 were analyzed to identify the dose distribution of each occupational group, total number of monitored workers, annual and collective deep (Hp(10)), eye (Hp(3)) and shallow (Hp(0.07)) doses. We further determined the individual and occupational group lifetime doses as well as the probability that monitored workers’ lifetime doses will exceed a specified lifetime dose level. The occupational groups with the highest radiation exposures were the nuclear medicine technologists, diagnostic imaging radiologists and diagnostic cardiologists. Although our data suggest that occupational doses reported are low, it is essential that exposure of occupationally exposed personnel are always kept as low as reasonably achievable with an effective radiation protection program. © The Author(s) 2020.

What is the main source of occupational radiation exposure?Occupational settings with ionizing radiation sources include: Medical and dental offices (e.g., X-rays). Hospitals and outpatient treatment centers, including specialty departments in: Radiology (e.g., medical X-rays and computed tomography (CT) scans).
Which contributes the most to occupational exposure of the radiologic technologist?Therefore, even though a radiologic technologist is not in the path of a radiation beam, he or she is susceptible to scatter radiation that mainly emanates from a patient. Scatter, or secondary, radiation is the main source of occupational radiation exposure.
Which of the following radiation monitors is most commonly used for monitoring occupational exposure in diagnostic imaging?Chapter 5. What is the most common dosimeter used to measure personnel exposure?Among all the personal radiation monitoring devices available, the Luxel dosimeter is considered the most sensitive one. It can detect 10 mrem of beta radiation and 1 mrem of X-ray and gamma radiation.
