Assessment of Radon Concentration in Buildings in Adamawa South Senatorial District, Adamawa State

This study presents an assessment of radon concentration levels in buildings within the Adamawa South Senatorial District, located in northeastern Nigeria. Radon, a naturally occurring radioactive gas, poses potential health risks, particularly when present indoors. The study aimed to determine indoor and outdoor radon concentrations, estimate the annual effective dose on the population, evaluate associated risks, and compare results with international standards to establish safety benchmarks. Sixty sample points were strategically selected across diverse geographical and environmental contexts within the senatorial district. Radon concentration measurements were collected using the Corentium Digital Radon Monitor over 48 hours. The findings revealed spatial variations in radon levels among different Local Government Areas (LGAs) within the district. Geological factors, such as soil composition and rock types, were identified as significant determinants of radon distribution. Building materials and designs also influenced indoor radon levels, with certain materials exhibiting higher concentrations than others. The study underscores the importance of targeted mitigation strategies and regulatory measures to reduce radon exposure risks and protect public health. Overall, the research contributes valuable insights into radon-related risks in the Adamawa South Senatorial District, providing a foundation for informed decision-making and intervention efforts to enhance indoor air quality and mitigate health hazards associated with radon exposure.
