APPLICATION: Model STG-AS44
is especially well suited to counting Alpha emission from
air sampler filters.
The STG-AS44 Alpha Scintillation System combines and Alpha Scintillation Detector plus TM-4 drawer system for sample containment. In this detection system, the protective window and grill are deleted to enhance sensitivity to Alpha radiation. Stainless steel drawer and base plate for stability and easy cleaning. The sensitivity of the STG-AS44 to 5MeV Alphas is typically 80-85% of 2Pi. It is completely insensitive to betas and gammas. Background is typically less than on count per minute. Sample cavity is 4 1/16'' diameter x 3/16'' deep. Allows 4'' sample diameter x 3/16'' thick sample size. Windowless operation, with light-tight housing and automatic HV. Cutoff when drawer is opened. |
