Radiation Monitors
Monitor 4
This radiation monitor is a compact, 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. An internally mounted beeper can be turned off for silent operation and it uses a 9V alkaline battery with up to 2,000 hours at normal background. It also comes with a 1 year limited warranty.
The detector is a halogen-quenched uncompensated GM tube with thin mica window 1.5-2.0 mg/cm2 thick and the display is an analog meter holding full scale in fields as high as 100X maximum reading. CPM/mR/hr scale default. Optional SI Meter Scale option available upon request.
The Monitor 4 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.
