The Radalert™ 50
| Please Note: The Radalert 50 has been discontinued - it has been replaced by the Radalert 100. |
The Radalert 50, our most
popular product, is a general purpose geiger counter. It measures
alpha, beta, gamma, and x-radiation. Its digital display shows readings
in your choice of counts per minute (cpm) or mR/hr, up to 50,000 cpm or
50 mR/hr, or in accumulated counts. A red LED blinks and a beeper
chirps with each count (the chirp can be muted). An audible alert
sounds when the radiation reaches a user-adjustable level. The Radalert
50 meets CE certification requirements for Europe.
Use the Radalert 50 to:
- 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
