OTC Radon Monitor

For Radon-222 and Radon-220

Overhoff Radon Monitor

The OTC Radon Monitor is intended to measure radon-222 and radon-220 over a wide range of concentrations. Gamma rejection is inherent in the pulsed ionization chamber design. This radon monitor is useful for confirming radon background levels or demonstrate compliance with regulations and to those individuals involved in radon
mitigation efforts.

The radon monitor can log 40,000 data points to accurately establish the daily variation in radon concentrations. The monitor’s internal rechargeable battery can operate the monitor for 24 hours. By utilizing the AC/DC adapter, the monitoring time can be extended indefinitely. Variations in radon concentrations due to the environmental effects of changes in barometric pressure and rainfall can easily be logged. The radon monitor is useful as a real-time radon monitor for those individuals involved in radon mitigation. Real-time indication gives an immediate indication of any mitigation efforts. Mitigation of radon concentrations can be as simple as a change in ventilation flow or a more complex effort such as installing a vapor barrier.
