OVERVIEW OF OCCUPATIONAL RADIATION EXPOSURE IN MEDICAL WORKERS IN SANTA CATARINA, BRAZIL, BETWEEN 2014 AND 2017.

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.

Assessments of medical exposures during interventional radiology procedures.

This study aims to contribute to the construction of a scenario regarding patient radiation exposure in Brazilian interventional radiology, aiming to provide data for the future drafting of specific legislation on interventional radiology because there is currently a lack of safety regulations for haemodynamics services in this country. Fourteen haemodynamics services in the states of Santa Catarina and Bahia were evaluated. The radiological devices were characterised through measurements of air kerma-area product, entrance surface air kerma (Ke), exposure time, spatial resolution (SR), low-contrast resolution and half-value layer.
