The InspectorAlert
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 μSv/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. |
·Monitor personal radiation exposure
·Monitor an area or perimeter
·Detect radiation leaks and contamination
·Ensure regulatory compliance
·Monitor changes in background radiation
·Demonstrate principles of nuclear physics
·Check for radioactive minerals in the earth |
