Impact of Structural and Environmental Parameters on Indoor Radon Gas Levels from Locations in Gombe, Adamawa and Yobe States Nigeria
Abstract
Indoor radon gas concentrations are influenced by structural and environmental factors, including ventilation rates, room volume, foundation floor thickness, indoor temperature, and relative humidity. This study investigates the impact of these parameters on radon accumulation in residential dwellings across Adamawa, Gombe, and Yobe States, Nigeria. Using Solid-State Nuclear Track Detectors (CR-39 SSNTDs), radon concentrations were measured over six months. Results indicate that poor ventilation, small room volumes, and high indoor temperatures significantly increase radon levels, while thicker foundation floors and higher relative humidity reduce radon accumulation/concentrations in an indoor spaces. Almost all the sampling locations considered in this study indicates high accumulated values of indoor radon gas above the recommended limit set by UNSCEAR, ICRP and WHO 100 Bq/m3. The findings highlight the need for improved building designs and ventilation systems to mitigate indoor radon gas accumulation and possible radon-related health risks.
