This paper is to evaluate radon concentrations emitted from Ordinary Portland Cement (OPC) mortar with industrial material (Granulated Blast Furnace Slag, GBFS) by sensing technology for continuous monitoring of indoor air quality. Semiconductor detector was chosen to measure the radon concentrations for over 24h to study daily variation. The detector is a patented electronic detecting device using a diffused-junction photodiode sensor to measure the concentration of radon gas. Since the cement mortar has the most critical role in the radon release process relative to other concrete constituents, and their contribution is dominant in the overall radium content of mortar, tests were carried out on cement mortar specimens with different GBFS contents, 0-40% by weight of the binder. It is found that the dosage of GBFS in cement paste has an influence on radon exhalation rate. The radon of OPC-GBFS material mortar is higher than that of reference mortar.
