Beta-Gamma Detectors : Ludlum Model 44-172 Beta & Beta Gamma Scintillation Detector

Ludlum Model 44-172 Beta & Beta Gamma Scintillation Detector Ludlum Model 44-172
Beta & Beta Gamma Scintillation Detector

Part Number 47-3543

The Ludlum Model 44-172 YSO (Yttrium Oxyorthosilicate) detector is used primarily for the detection of low-energy gamma radiation, from approximately 5 keV to 145 keV. It will also detect beta energy as low as 49 keV. The detector consists of a 1-inch diameter by 1-millimeter thick YSO scintillator. The window area is approximately 5 cm.
