Abstract: The purpose of this study is to measure and monitor the radon concentration in a fabricated \nfoamed light concrete. Various proportions of Portland cement, mine sand, water and foamed were \nused in fabricating foamed light concrete. The concentration of radon released from the fabricated \nconcrete was measured using Radon Monitor Model 05-420 from the Honeywell Inc. U.S.A. Results of \nthis research showed that the mean radon concentration in foamed light concrete was 1.9pCi/L. The \ncurrent radon concentration was proportional to temperature and inversely proportional to humidity. \nGradual increased of radon concentrations were detected after three days of measurements, indicating a \nbuild up of airborne Rn due to Rn emanations from the fabricated foamed light concrete. \nHowever,with proper ventilations, the accumulation of the Rn emanated can be further reduced below \nthe measured level. From this research finding, the fabricated foamed light concrete can beutilized as \none of the alternatives to reduce radon concentration levels in human environment
