Monitor 4 & 4EC Handheld Radiation Alert® DetectorDetector: Monitor 4: Halogen-quenched uncompensated GM tube with thin mica window 1.5-2.0 mg/cm2 thick.Monitor 4EC: Halogen-quenched GM tube, energy compensated sidewall 2mm tin filter. Thin mica window 1.5-2.0 mg/cm2 thick.Display: Analog Meter holds full scale in fields as high as 100X maximum reading.Sensitivity: M4: 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.M4EC: is the Same as Monitor 4 except the energy response for gamma and x-rays through the detector sidewall is flat within +61% or -26% over the range of 40 keV to 100 keV, and within +35% or -17% over the range of 100 keV to 1.3 MeV.Gamma Sensitivity: Operating Range: 1000 CPM/mR/hr (referenced to Cs-137)Energy Sensitivity for the 4EC is the Same as Monitor 4 except the energy response for gamma and x-rays through the detector sidewall is flat within +61% or -26% over the range of 40 keV to 100 keV, and within +35% or -17% over the range of 100 keV to 1.3 MeV.Operating Range: 0-.5, 0-5, 0-50 mR/hr                 0-500, 0-5,000, 0-50,000 CPM or 0-500 µSv/hr                 0-50 mR/hr.Range Switch: X1, X10, X100, Battery Check.Accuracy: Typically ±15% of reading (referenced to Cs-137)

RAD-60 - Personal Alarming Dosimeter and Rate Meter"The RADOS RAD-60 Personal Alarm Dosimeter is a precise and reliable instrument for ensuring the personal safety of the user. Ideally, the RAD-60 is used in everyday radiation monitoring, in stand-alone conditions. If your needs grow for a more sophisticated system, the versatile RAD-60 can also be integrated into an Access Control System. The RAD-60 can be switched into System Mode, for the purpose of tracking Personnel Dose records and generating compliance reports."     - compensated Si-DiodeButton FunctionsFront panel button has the following functions:change display priority (dose/dose rate)switch ON/OFFchirp ON/OFFreset integrated dosechange alarm thresholdsactivate battery testMeasurement RangeDose: 1 uSv - 9.99 Sv or 0.1 mrem - 999 remEnergy ResponseHp(10), 60 keV - 3 MeV, better than + or - 25%, up to 6 MeV, better than + or - 35%Dose Rate5 uSv/h - 3 Sv/h or 0.5 mrem/h - 300 rem/hDose Rate LinearityBetter than + or - 15% up to 3 Sv/h (300 rem/h) ConnectorsInfrared communication via bottom of the dosimeterPower RequirementsOne triple A alkaline cell, typical life is 1800 hours in background (dose mode)Temperature Range-20 - + 50° C operational, humidity up to 90% RH, non-condensed -20 - + 70° C storingWeight80 g (including battery)
