Highly sensitive family of radiation portal monitors to monitor a railway line. The portal monitors detect even slightest traces of the hidden radioactive materials and locate a car with radioactive substances. The radiation portal monitors of PM5000A series designed for use in the harsh environment and can be used in extreme climate conditions.
 |
The monitors are designed for installation at customs and border checkpoints to prevent the illicit trafficking of nuclear and radioactive materials. The monitors can be also installed at the areas considered to be potential target for terrorist attack or to monitor limited access areas, such as areas where radioactive materials are used or reprocessed.
The unique feature of the PM5000A Railway Monitors is that they are configured with one multipurpose gamma/neutron radiation detector module. Detector modules are mounted on special metal supports with concrete foundations. The railway monitors are equipped with video monitoring systems, computer and pager communication with the specialists, assigned to the radiation monitoring. If necessary, the monitors can be additionally equipped with wheel counters to pin-point the car that caused the alarm.
The monitors are ideally suited to the extreme climatic or environmental condition. They have outstanding performance in the areas with high vibration and electromagnetic interference created by the contact system and the moving trains.
The following configurations of the PM5000A monitors are recommended for railway monitoring:
Depending on the specific requirements for sensitivity of the monitors, site of installation etc., configurations with a greater number of detector modules can be provided.
