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

Int J Environ Res Public Health. 2019 Nov 15;16(22):4523. doi: 10.3390/ijerph16224523.


In this work, the partition coefficients K and diffusion lengths L D 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 K ( T ) , the diffusion lengths L D ( T ) , and the permeabilities P ( T ) 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.
