Current status,influencing factors and management challenges of indoor radon levels

Abstract

Abstract: Radon and its progeny,when inhaled by humans,deposit in the lungs and release alpha particles during radioactive decay,which can damage body cells and increase the risk of lung cancer. Radon and its decay products in residential environments are the second leading cause of lung cancer. This paper comprehensively elaborates on the hazards of radon,the differences in indoor radon concentrations in different building types,the multi-factorial effects on indoor radon content,as well as the current status of indoor radon control levels and standards. Given that children are more sensitive to the potential risks of radon,there should be a particular focus on indoor radon levels in schools and childcare institutions. Currently,various countries have established indoor radon standards for different settings. Through in-depth analysis of these aspects,this article reveals the problems and challenges faced in the current indoor radon research field,and proposes targeted suggestions and prospects,aiming to provide comprehensive and in-depth references for scientific researchers,policymakers,and relevant practitioners,so as to promote more scientific and effective management and response to indoor radon issues.

Key words: Indoor radon, Lung cancer risk, Differences in building types, Influencing factors, Control standards
