Occupational Safety and Hygiene V - Proceedings of the International Symposium on Occupational Safety and Hygiene, SHO 2017
The main purpose of this study was to address the contribution of the exposure from non-occupational exposure to the total effective dose of workers from thermal spas. Radon indoor concentrations were measured in 14 Portuguese thermal spas and in the dwellings of 14 selected workers, one from each thermal spa. Different types of questionnaires were used to characterize the thermal spas and the dwellings. Indoor radon concentration was measured by a passive method with CR-39 detectors. The results showed that, in some cases, the non-occupational (residential) exposure to radon, and the contribution to the total effective dose, is much higher than the occupational exposure. Is addition, most of the workers have remained at the same workplace for the last 20 years, which may represent a significant risk to health due to the continuous annual doses at which they have been exposed to, over the years. © 2017 Taylor & Francis Group, London.
