Determination of the content of 85Kr and 133Xe in air using a krypton-xenon mixture

Abstract

A procedure was developed for determining radioactive isotopes of Kr and Xe in air using a krypton-xenon mixture (KXM) produced at air separation plants. The procedure allows determination of background volume concentrations of Kr and Хе at long distances from sites of their injection using common spectrometric apparatus. The results of monitoring volume concentrations of 85 Kr and 133 Xe in Cherepovets in 2006-2008 are presented.
