The inspector alert - radiation detector geiger counter
Handheld Surface Contamination Monitor
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 or Sv/hr, CPM, or CPS. 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 radiation reaches a user-adjustable level. The Inspector Alert meets CE certification requirements for Europe.

Check for radioactive minerals in the earth
Halogen-quenched Geiger-Mueller tube. Effective diameter 1.75" (45 mm). Mica window density 1.5-2.0 mg/cm2.
Display updates every 3 seconds, showing the average for the past 30-second time period at normal levels. Averaging period decreases as radiation level increases. User can select fast 3-second averaging period.
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
