In the event of a nuclear plant accident where the nuclear fuel has been damaged, radioactive cesium compound gaseous species can be released into the nuclear plant environment. In this work, a microwave generated plasma is generated the cesium from cesium compounds (CsI, CsCl etc.). An Argon gas based microwave generated plasma is used as the ionization chamber. The characteristics of the plasma and the iodine species is observed. The released gaseous species are capture in a filter system and the characteristics of the cesium species are identified. The results indicate that Cs species are observed. The technique can be used to address contaminated material as well as treat the gas phase environment.
