The TSA TM850 automatically screens railroad or vehicular traffic without the need for frequent calibration. High sensitivity allows the TM850 to be used at transportation hubs requiring a wider installation area and high throughput such as at ports and customs and border entry points. The TM850 is designed for use in harsh environmental conditions.

Advanced Design Features
The TSA TM850 is a train and large vehicle monitor with excellent sensitivity and reliability. The TM850 consists of two self-contained, weather resistant pillars placed on either side of the railroad track or roadway to be monitored. Each pillar contains two large plastic scintillator detectors, four neutron detector blocks with either two or four neutron detectors each, multiple occupancy sensors, and an amplifier. The master pillar also has a battery, power supply, battery charger, and a system controller.
Programmable Detection Parameters
Selectable settings for sensitivity, energy discrimination, and fault levels may be entered by the administrator.
When the system is powered up, it takes twenty seconds to acquire an initial background. The background is continually updated until the system is occupied. When the TM850 senses occupancy, the system starts comparing the current count to the most recent background data. Alarm comparisons are made every 200ms. If the count exceeds the alarm level, both audible and visual alarms will be triggered. The system monitors itself and indicates low and high background conditions.
Flexible Detection Options
The TSA TM850 is available in three configurations; Gamma, Neutron or a combination of Gamma and Neutron detection. Gamma provides detection of ionizing radiation and Neutron provides detection of Special Nuclear Materials (SNM) while the combined Gamma and Neutron provides the most powerful detection capabilities for radioactive isotopes even in shielded materials.
With the optional Remote Alarm Panel operators can view alarms up to 300m from the monitor. The TSA TM850 is compatible with TSA RAVEN™ communications software designed to both capture and view data and video images relating to a radiological detection incident.
