Vehicle monitoring radiation detection systems

The RC4000 series of vehicle radiation detection systems have been designed to detect very low Gamma Ray emissions in high density materials.


Design of the RC4000 incorporates over 20 years of engineering design and proven field application experience. The RC4000 utilizes advanced proprietary real time statistical algorithms to compensate for the fluctuations in background radiation caused by varying material densities to provide reliable and accurate detection. Superior NORM discrimination technology reduces false alarms.


The RC4000 is available in a variety of sizes and configurations, with the most common systems listed below. The vehicle size and type help determine the appropriate panel size and configuration. All RC4000 systems utilize high quality PVT scintillators, electronics and dual Photomultiplier Tubes (PMT). Remote access capability is available to provide technical support, software updates and electronic hardware adjustments.
