In this work, the partition coefficients and diffusion lengths L D of radon in some polymers are experimentally determined for several temperatures in the range = 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.
在这项工作中，实验测定了氡在几种聚合物中的分配系数 和扩散长度 L D ，温度范围为 = 5-31°C。将一些得到的值与给定温度下可用的已发表数据进行了比较。结果表明，在所研究的温度范围内，分配系数 K ( T ) 、扩散长度 L D ( T ) 和渗透率 P ( T ) 的温度依赖性可以进行分析描述。这允许在给定的温度范围内估计这些量，并定量描述在研究的聚合物中氡的传输。
