Evaluation of Standardized Ge(Li) Gamma Ray Detectors for Low Level Environmental Measurements

Counting sensitivity for stardardized Ge(Li) detectors has been determined for a large number of detector-sample geometries and counting conditions. It has been found that relatively simple systems can satisfy a majority of applications, thereby resulting in a favorable cost-effective approach to enviromental measurements. Recommendations are made for the improvement of significant counting parameters for speific applications, resulting in the maximum counting capability for a given detector system.
