RAPISCAN-TSA TM-850 LARGE VEHICLE – TRAIN RPM
The Rapiscan/TSA TM-850 is designed to automatically scan railroad traffic without the need for frequent calibration. t is intended for applications where the relatively low energy emissions from 235U and 239Pu are the main concern. TM-850 consists of two self-contained, weather resistant pillars placed on either side of the railroad track to be monitored. Each pillar contains two plastic scintillator detectors, four neutron detector blocks, occupancy sensors, and an SCA-775 amplifier/controller.
