Abstract

This study evaluates indoor radon (^222Rn) concentrations and associated radiological risks in various dwellings within industrial sites of Kannur district, Kerala, focusing on the influence of construction materials such as marble, granite, concrete, and mud. Using pinhole-based dosemeters with LR-115 Solid State Nuclear Track Detectors and Direct Radon Progeny Sensors (DRPS), radon levels ranged from 102.30 to 184.75 Bq/m³, all within International Commission on Radiological Protection (ICRP) limits but exceeding the world average annual effective dose and excess lifetime cancer risk values recommended by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) 2000. Houses with marble floors and concrete roofs exhibited the highest radon concentrations, suggesting that natural radioactivity in construction materials significantly contributes to indoor radon levels, alongside factors like ventilation and building condition. The findings highlight potential health risks from prolonged radon exposure in such dwellings and underscore the importance of monitoring radon in relation to building materials and environmental conditions.
