Partition Coefficients and Diffusion Lengths of (222)Rn in Some Polymers at Different Temperatures

In this work, the partition coefficients K and diffusion lengths [Formula: see text] of radon in some polymers are experimentally determined for several temperatures in the range T = 5–31 °C. Some of the obtained values are compared to published data available for the given temperatures. It is shown that the temperature dependencies of the partition coefficients [Formula: see text] , the diffusion lengths [Formula: see text] , and the permeabilities [Formula: see text] could be described analytically for the studied temperature range 5–31 °C. This allows estimation of these quantities in the given temperature range and quantitative description of the transport of radon in the studied polymers.
