Digilert 100 Handheld Digital Radiation Alert® Detector
The Digilert 100 measures alpha, beta, gamma, and x-rays. Its digital display shows readings in your choice of counts per minute (CPM) or mR/hr, or in accumulated counts. A red LED flashes and beeper sounds with each count detected and when the radiation reaches a user set alert level.
Specifications
Detector
Halogen-quenched GM tube with mica end window. Mica window density 1.5-2.0 mg/cm2. Effective window diameter is .360 inch. Side wall is .012 inch thick.
Display
4-digit liquid crystal display with mode indicators. Display updates every 60 sec.
Count Light
Red LED flashes with each count.
Audio Indicator
Sounds with each count (can be switched off for silent operation).
Alert
Pulsating beeper sounds the alert. Three separate adjustable alert levels are used for mR/hr, CPM, µSv/hr:, and Total.
Outputs
Dual miniature jack sends counts to CMOS- compatible devices, including computers, data loggers, and educational data collection systems. Submini jack provides audio output to an external earpiece, amplifier, or tape recorder.

Operating Range |
|
mR/hr - .001 (1µR) to 100 mR/hr
µSv/hr - .01 to 1000
CPM - 0 to 350,000
CPS - 0 to 5000
Total/ Timer - 1 to 9,999,000 counts
Gamma Sensitivity
1000 CPM/mR/hr referenced to Cs-1 37.
Accuracy
±10% typical (NIST), Typically ±15% of reading. |
Energy Sensitivity
• Detects alpha down to 2.5 MeV; typical detection efficiency at 3.6 MeV is greater than 80%.
• Detects beta at 50 keV with typical 35% detection efficiency.
• Detects beta at 150 keV with typical 75% detection efficiency.
• Detects gamma and x-rays down to 10 keV typical through the window, 40 keV minimum through the case. Normal background is 5-20 CPM. |
Anti-Saturation
Readout will hold at full scale in high radiation fields as high as 100 times the maximum reading.
Power
One 9-volt alkaline battery.
Battery Life
Battery life is typically 2000 hours at normal background radiation levels.
Temperature Range
-10° to +50°C (14° to 122° F)
Weight
117 grams (6.5 oz.) without battery.
Size
150 x 80 x 30 mm (5.9 x 3.3 x 1.2 in.).
