Alpha & Beta Meters

Alpha/Beta Data Logger
 Model 2360 Ratemeter/Scaler with Model 43-93 Detector CE_Label
M2360-w-43-93

This instrument will simultaneously measure alpha and beta as separate counts and also data log the results.  The 2360 meter is an analog/digital unit with ratemeter, scaler, and data logging functionality and is equipped with the overload indicator, which typically signals a light leak in the detector mylar window. The detector is 100 cm2 with a  ZnS(Ag) adhered to a 0.254 mm  (0.010 in.) thick plastic scintillator.  The 1.2 mg/cm2 mylar window has a protective screen  cover that results in 89 cm2 open area.   The alpha-to-beta cross talk is less than 10% with the beta cross-over to alpha at less than 1%.  The backgrounds are typically < 3 cpm alpha and < 300 cpm beta.  Efficiencies (4 pi) are 20% - 239Pu; 15% - 99Tc; 20% - 90Sr/Y.

Beta Measurement
Model 3 Ratemeter with Model 44-142 Detector CE_Label
M3-w-M43-92

The Model 3 analog survey meter combined with the Model 44-142, 100 cm2 beta detector, offer a great way to measure beta radiation.  The meter is equipped with the overload option, which typically indicates a light leak in the detector mylar window. The detector is a 0.254 mm (0.010 in.) thick plastic scintillator.  The window is 1.2 mg/cm2 mylar with a protective screen resulting in 89 cm2 open area.  In a 100 nSv/h (10 uR/hr) field, background count rates are typically in the 300 to 350 cpm range.  Efficiencies (4 pi) are typically 4% - 14C, 30% - 90Sr/Y, and 20% - 99Tc.
