Indoor radon monitoring for occupational health reinforcement in Portugal: compliance, prevention, and technological advancements

This article highlights the relevance of indoor radon monitoring for occupational health protection, disease prevention, and compliance with safety regulations. Radon, a colorless, odorless, and tasteless radioactive gas, is a leading cause of lung cancer after tobacco smoking, and therefore in situ monitoring is fundamental to identify areas with high radon levels so that remediation measures must be implemented to reduce indoor exposure. The article gives an overview of the regulations in force in Portugal for indoor radon monitoring and identifies the responsibilities of different authorities and organizations in ensuring compliance with radiological protection requirements. It also outlines the legal framework for radon protection in Portugal, including the identification of reference levels for radon concentration in workplaces and dwellings, and the need to implement measures concerning indoor radon exposure reduction. Additionally, it is detailed the process of monitoring radon in indoor environments, including the selection of an appropriate measurement device and the necessary measurement time, and the need to inform and train workers about the risks associated with radon exposure. In short, this review provides information on the importance of radon monitoring and the measures required to ensure public safety.
