Influence of Humidity on Building Material's Radon Exhalation Rate
In this paper, the humidity of building materials were controlled by adopting the inorganic salts saturated solutions, and the radon exhalation rate of building materials were measured by the active carbon method which under the different humidity conditions. The result indicates that with the humidity increasing, the radon exhalation rate of building material first increasing and then decreasing; The average roundish radius of building material bigger, the speed of radon releasing coefficient arrival the saturation point was quicker; the porosity and humidity was bigger, the radon diffusion coefficient descended was quicker. Under the relative humidity of 56%-96%, the active carbon box with diffusion base may effectively reduce the influence of humidity on active carbons radon absorption, but under the relative humidity of 56%, the active carbon box with diffusion base may not affect the humidity to active carbons radon absorption.
