Abstract
Fission product /sup 133/Xe and /sup 135/Xe are released to the atmosphere during normal reactor operation. With increasing numbers of nuclear power stations there will be an increase in the ambient level of these isotopes. They do not present an appreciable long-term health hazard because of their inert nature and relatively short half-lives. However, their presence in the air of a whole-body counter may interfere significantly with in vivo low-energy photon counting procedures by contributing to the background count-rate in the energy region below 300 keV. This applies particularly to lung and whole-body measurements with dual thin crystal NaI(Tl)-CsI(Tl) scintillation detectors for actinide nuclides. It is important, therefore, that gamma spectroscopists should be aware of the possible presence of /sup 133/Xe and /sup 135/Xe in the air of their whole-body counting facilities, particularly if these are near to reactors and do not have traps for removal of inert gases from their air supplies.
