The Handheld Digital Radiation Alert Detector measures alpha, beta, gamma and x-ray radiation. It is specifically designed with the ability to recognize the smallest changes in radiation levels and have high sensitivity to many of the common radionuclide. This unit counts all ionizing events and immediately shows the results on the LCD monitor. With this device you have the freedom to choose what unit of measurement you would prefer for these results to be shown in; which can easily be adjusted with the mode switch.
To detect radiation, the Handheld Digital Radiation Alert Detector uses a Geiger-Mueller tube. Each time radiation passes through this tube and causes ionization the tube will generate an electrical current pulse. Every time this occurs, each pulse is recognized and the detector keeps a record of this. Every count varies depending on the levels of radioactivity at the given time. To fully calculate and understand the radioactivity in the given space it is better to be analyzed over a period of time.

Spec Summary:
Detector:
Internal Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 aerial density. Effective diameter of window is 1.75 in. (45 mm). Radiation symbol on front label marks the center of the detector.
Display:
4 digit liquid crystal display with indicators
Averaging Periods:
Display will update every 3 seconds. At low background levels, the update is the moving average for the past 30-second time period. The timed period for the moving average decreases as the radiation level increases
Operating Range:
CPM - 0 to 300,000
mR/hr - .001 (1µR) to 100 mR/hr,
µSv/hr - .01 to 1000,
CPS - 0 to 5000
Total/ Timer - 1 to 9,999,000 counts

Internally mounted beeper ( can be switched off for silent operation)
Timer:
Can set 1 minute sampling periods from 1 minute to 10 minutes. 10 minute sampling periods from 10 minutes to 60 minutes. 1 hour sampling periods from 1 to 24 hours.
Outputs:
Dual miniature jack drives CMOS or TTL devices: count to computer or datalogger. Submini jack input allows for electronic calibration
Anti-Saturation:
Readout holds at full scale in fields up to 100 times the maximum reading
Power Requirements:
One 9-volt alkaline battery. Battery life is minimum 200 hrs at normal background. Minimum 24 hrs at mR/hr.
