Objectives: A radon emission reducing agent was prepared using charcoal and zeolite, and the amount wasmeasured after coating construction materials with the agent. The availability of the radon emission reducingagent was evaluated.
Methods: Construction materials (red brick, cement brick, and gypsum board) coated with reducing agent wereplaced in a chamber to measure radon emissions. The construction materials were coated one through threetimes. The spread volume for brick and gypsum board was 50 mL and 75 mL per application, respectively. Theamount of radon emitted was measured by RAD-7 after 48 hours.
Results: The reduction ratio increased with the number of coatings, and the reduction ratios for red brick, cementbrick, and gypsum board were 63.3, 73.6, and 58%, respectively, in the case of three coatings of RA-1. Thereduction ratios for red brick, cement brick, and gypsum board were 42.8, 58.1, and 26.2%, respectively in thecase of three coatings with RA-2. RA-1 was slightly better than RA-2 in radon emission reduction.
Conclusions: Radon emissions from construction materials decreased according to the concentration of reducingagent coating, and it was more effective than existing methods.
