Solubility of krypton, xenon and radon in polycarbonates. Application for measurement of their radioactive isotopes

摘要

Bisphenol-A polycarbonates have a high absorption ability for noble gases that can be employed for sampling and measurement of radioactive isotopes of these gases. In this report the solubility of krypton, xenon and radon in the specified polycarbonates is determined by measurement of ~(85)Kr, ~(133)Xe and ~(222)Rn absorbed in polycarbonate specimens. The found solubility is used to develop a general methodology for measurement of radioactive noble gases in air and water. The methodology is tested in pilot measurements of ~(133)Xe in air under real conditions. The results demonstrate sufficient potential for practical applications.
