Survey of radiation protection utilization and accessibility within Australian cardiac angiography laboratories

Highlights - Staff adequately use ceiling-mounted lead and thyroid shields. - The use of lead caps and lead glasses is inconsistent and requires improvement. - Awareness of risk does not translate to staff use of radiation head protection. - Radiation education and training needs to be provided to occupationally exposed staff. Abstract Continuing improvements in both catheterization and imaging equipment have resulted in greater numbers and increasingly more complex angiographic cases being performed, which has led to higher patient and staff doses. Occupational radiation exposure to staff within fluoroscopic suites has been demonstrated to elevate the risk of carcinogenesis and radiation-induced cataracts. A survey was undertaken to compare the accessibility and utilization of radiation protective equipment by staff within a selection of cardiovascular suites throughout Australia. A number of Australian cardiovascular suites were invited to complete an online survey comprising 10 questions. The survey questions focused on the availability and use of head, thyroid, and eye radiation protection by doctors and nurses present in the room during cardiac angiography procedures. The study identified that the utilization of ceiling-mounted lead and thyroid shields was adequate within the surveyed departments but has highlighted that there are areas that staff could further reduce their risk of the occupational exposure. There is very strong evidence proving the importance of additional shielding such as lead caps and glasses in minimizing dose, and there needs to be a focus on education to ensure that staff are cognizant of the benefit of wearing them. It is advisable that staff working within angiography suites have access to appropriate radiation protection devices to minimize their exposure to ionizing radiation. In addition, training should be provided to staff regarding the risk of occupational exposure and dose optimization.
