Handheld Surface Contamination Meter
The Inspector Alert measures alpha, beta, gamma and x-radiation using a 2-inch "pancake" GM detector with high sensitivity to common beta and alpha sources.
The easy-to-read digital display shows readings in your choice of mR/hr, CPM, CPS, or μS/hr. The Total/Timer feature allows timed readings from one minute to 24 hours for precise measurement of low level contamination. An audible alert sounds when the radiaiton reaches a user-adjustable level.
?      Quickly alerts first responders to the presence of harmful levels of nuclear radiation
?      Improves safety in the laboratory and in the field
?      Automatically compensates for GM tube dead time
?      Will not jam in high radiation fields
?      Meets CE certification requirements for Europe
Specifications:
Detector: Halogen-quenched Geiger-Mueller tube. Effective diameter 1.75" (45 mm). Mica window density 1.5-2.0 mg/cm2.

CPS: 0 to 5,000
Gamma Sensitivity: 3500 CPM/mR/hr referenced to Cs-137
Smallest detectable level for I-125 is .02 μCi at contact
Efficiency: For 4 pi geometry at contact
        Beta
C-14 (49 keV avg. 156 keV max.): 5.3%
Bi-210 (390 keV avg. 1.2 MeV max.): 32%

Alpha
Am-241 (5.5 MeV): 18%
Averaging Periods: Display updates every 3 seconds, showing the average for the past 30-second time period at normal levels. The averaging period decreases as the radiation level increases. User can select fast 3-second averaging period
Timer: Can set 1-10 minute sampling periods in one-minute increments, 10-50 minute sampling periods in 10-minute increments, and 1-24 hour sampling periods in 1-hour increments
Alert: Beeper sounds the alert
User-adjustable alert level is set using three buttons
