ABSTRACT
This study presented a model applied for potential risk assessment in an interventional radiology setting. The model of potential risk assessment (MARP) consisted of the creation of a scale of indicators ranging from 0 to 5. The radiation levels were categorized according to gender, kind of procedure, value of kerma air product (Pka), and accumulated radiation dose (mGy). The MARP model was applied in 121 institutions over 8 y. A total of 201 656 patient radiation doses (Dose-area product and accumulated kerma) data were launched into the system over time, with an average of 22 406 doses per year. In the context of the workers (cardiologists, radiographers, and nurses) monitored during the MARP application, 8007 cases (with an average of 890 per year) of occupational radiation doses were recorded. This study showed a strategy for quality evaluation in fluoroscopy using a model with a compulsory information system for monitoring safety.

This study assessed occupational radiation doses in Santa Catarina, Brazil, from 2014 to 2017. Data were collected from Sistema de Informação Estadual de Radiações Ionizantes (SIERI), a compulsory occupational dose registration system established in Santa Catarina in 2014. Most doses were registered as lower than the dosemeter recording level (RL; 99.12%). Diagnostic radiology workers registered doses higher than the RL (61.13%) more frequently than nuclear medicine workers; however, the former received lower doses. Nuclear medicine workers represented 38.87% of dosemeter values higher than the RL, but their mean doses were higher. The professionals who registered the highest doses across both categories were radiology technologists/technicians and nursing workers. Establishment of a compulsory information system is important for monitoring the safety of workers. This study compiled data from the first few years of the SIERI program. Here, we report the current status of exposure in Santa Catarina.
