Radiation Survey Meter, Alpha, Beta, Gamma and X-rays

Description Monitor 4, Radiation Alert Quality Handheld Detector This is a general purpose survey meter capable of detecting alpha, beta, gamma, and x-rays over 3 selectable ranges.  A red count light flashes and a beep sounds with each event detected. Specifications:Detector: Halogen-quenched uncompensated GM tube with thin mica window 1.5-2.0 mg/cm2 thick.Display: Analog Meter holds full scale in fields as high as 100X maximum reading.Monitor 4 Energy Sensitivity: Detects alpha down to 2.5 MeV; typical detection efficiency at 3.6 MeV > 80%. Detects beta at 50 keV with 35% efficiency.  Detects beta at 150 keV with 75% efficiency.  Detects gamma and x-rays down to 10 keV through the window, 40 keV minimum through the sidewall.  Normal background is approximately 10-20 CPM.Battery: Comes complete with 9V batteryCalibration: Calibrated for 12 months from date of sale documentation Related Products Battery, Troxler Battery for 3440, 3430 and 4640B Troxler Nuclear Soil Moisture Density Gauges $87.40 Add to cart CPN MC1, CPN MC2 Battery Charger, Plugs Into Car Cigarette Lighter $90.85 Add to cart Battery Pack For MC1DR and MC1DRP CPN Soil Moisture Nuclear Density Gauges $48.35 Add to cart Instrotek MC-3 Elite Nuclear Soil Moisture Density Gauge Call for Price Read more
