Abstract :
The performance characteristics of a high efficiency, high resolution (20%-1.85 KeV) Ge(Li) gamma-ray detector have been evaluated and are compared with a lower efficiency (13%) Ge(Li) system having NaI Compton suppression. This comparative evaluation, based on the analysis of low level environmental samples, indicates that the high performance detector generally provides better sensitivity than a comparably-priced Compton suppression unit.
