ABSTRACT
Proportional counters and a ß-γ coincidence system and their performance characteristics are described, with emphasis on internal and external quality controls. Typical limits of detection (LD) are 8mBqm-3 for 85Kr and 4mBqm-3 for 133Xe for the proportional counters, while for similar xenon volumes the LD for 133Xe in the ß-γ system is approximately 4 times lower. Results of comparative analyses agree above the limit of quantification. Xenon-133 levels in southern Germany are presently at or below the LD of the proportional counters, but above the LD of the ß-γ system, which is now routinely used for analysis of environmental samples.
