含氡放射性水体氡析出规律的理论研究

Abstract

Abstract: One dimensional differential equation for radon migration in the water containing radon was established using radon seepage-diffusion migration theory and the formula for calculating the concentration of radon in water and the radon exhalation rate at the water surface were derived. In addition, the variation of radon concentration in water and radon exhalation rate at the surface of water were studied when parameter changes such as radon exhalation rate from the emanation medium at the bottom of water body, radon transfer rate, radon diffusion coefficient in water and the depth of the water. The results showed that:when the other parameters remain unchanged,(1)The concentration of radon at the same depth of water and radon exhalation rate on water surface increases with the increase of radon exhalation rate from the emanation medium at the bottom of water body;(2)The concentration of radon at the same depth of water decreases and radon exhalation rate on water surface increases with the increase of radon transfer rate; Furthermore, when radon transfer rate is larger than 1×10^-6m/s, the change of radon exhalation rate on water surface is not obvious with the change of radon transfer rate;(3)The concentration of radon at the same depth of water and radon exhalation rate on water surface increases with the increase of radon diffusion coefficient in water;(4)The concentration of radon in water that close to the surface and radon exhalation rate on water surface decreases with the increase of water depth.
