Objective To explore the effects of temperature and relative humidity on Rdon ex halation rate of glazed tile in hermetic environment.
Methods Ordinary glazed tile was used as experimental object to detect Radon concentration with Model 1027 continuous Radon monitorin a 01 25m3 hermetic simulation chamberat amerent temperatures and humidities, then Radon exhalation rates were calculated.
Results In reasonable range, the correlations between Radon exhalation rates and temperature, as well as relative humidity could be expressed as ER=-0.0293T3+2.5543T2-72.82T+687.27(R2=0.9669)and ER=0.0001RH3-0.0354RH2+2.3391RH-25.044(R2=0.9889), respectively.
Conclusion Environmental temperature and relative humidity have great effects on Radon exhalation rate of glazed tile.
