Radon gas emission from home appliances: Understanding sources, implications, and mitigation strategies

Abstract

Radon gas, a naturally occurring radioactive gas, has garnered increasing attention due to its potential health risks when present in indoor environments. While it is well-known that radon can enter homes through the ground, an often overlooked source of radon is home appliances. This comprehensive review paper explores the emission of radon gas from various home appliances, shedding light on an aspect of indoor radon exposure that has not received as much scrutiny. This review discusses the sources of radon in homes, covering both natural and artificial origins, and highlights the key factors influencing radon entry. It delves into the mechanisms through which home appliances can emit radon, identifying common appliances that have been associated with radon release. Furthermore, the paper outlines measurement and detection techniques for assessing indoor radon levels, emphasizing the importance of regular radon testing in homes. The health effects of radon exposure are discussed in detail, with a focus on the epidemiological evidence linking radon to lung cancer and associated risk assessments. Mitigation strategies, including techniques for reducing radon levels and radon-resistant construction methods, are explored as effective measures to lower indoor radon concentrations. Regulations and guidelines governing radon exposure in homes are highlighted, providing insights into the legal framework and recommendations for safe radon levels. The review also presents case studies from different regions and successful radon mitigation initiatives, offering practical insights into addressing radon issues. The paper concludes by discussing future research directions and emerging technologies aimed at reducing radon emissions from home appliances, emphasizing the importance of continued efforts to raise awareness, test for radon, and mitigate its presence. Overall, this review aims to contribute to a deeper understanding of radon gas emission from home appliances, its implications, and the measures to safeguard indoor air quality and public health.
