Abstract : Abstract - Radon is a natural and a nonreactive gas, and in ranking is second to smoking as the cause of lung cancer. The less ventilation of indoor environments is a significant concern as gas can accumulate, and the concentrations become very high. This research examines radon concentration in homes from Ogun and Ibadan Southwest of Nigeria. RADEX MR107 radon detector utilized to measure radon levels inside homes. The radon concentration varies from 30Bqm^(-3) to 57Bqm^(-3) with a cumulative mean of 39.6Bqm^(-3). The annual absorbed and effective dose values are 0.72mGy/yand 1.73mSvy^(-1) respectively. The estimated average annual effective dose is higher than the world permitted value of 1mSvy^(-1). The total mean concentration of radon from study Areas in Ibadan and Mowe is 41.5 Bqm-3; this is higher than the mean permissible value of 40 Bqm-3. This research shows that ventilation plays a vital role in radon concentration in the home. Keywords - Radon, Concentration, Absorbed Dose, Cancer Risk, Ventilation
