Abstract: Radon-222 is a naturally occurring radioactive gas that contributes significantly to indoor radiation exposure. This study presents a localized assessment of radon-222 fluctuations and a validation exercise conducted at a specific GPS coordinate—9.8097° N, 6.1553° E—in Zungeru, Nigeria. The Corentium Airthings Digital Radon Monitor was used to measure real-time indoor radon concentrations continuously over 90 days. The data revealed significant fluctuations associated with daily cycles, weekly patterns, and prevailing weather conditions. Recorded radon levels ranged from 28.49 Bq/m³ to 120.8 Bq/m³. The monitor categorized the radon measurements into Short-Term Average (STA), Seven-Day Average (SDA), and Long-Term Average (LTA). The minimum, maximum, and mean values observed for each were as follows: LTA: 40.33, 96.94, 83.64 Bq/m³; STA: 28.49, 120.80, 87.44 Bq/m³; SDA: 42.92, 98.42, 79.91 Bq/m³. All recorded concentrations remained below the 200 Bq/m³ exposure limit recommended by the International Commission on Radiological Protection (ICRP). The device's performance was validated through consistency checks under varying indoor temperature and humidity conditions. This study affirms the reliability and accuracy of the Corentium Airthings monitor for localized environmental health assessments and highlights the potential of integrating such affordable, portable tools into Nigeria’s broader public health and radiation monitoring frameworks. This project is sponsored by the Industrial-Based Research initiative of the Tertiary Education Fund (TETFund), a program provided by the Nigerian government, and is being conducted by the Salihu Mohammed research group at Niger State Polytechnic in Zungeru.
