  RADIATION MONITORING SYSTEM "TSRM61"
 

Radiation monitoring system TSRM61 Radiation monitoring system TSRM61 booklet (PDF ~ 1,39 Mb)

PURPOSE:

  • automatic detection of nuclear and radioactive materials (NRM) substances to prevent illicit trafficking through pedestrian and transport checkpoints;
  • monitoring the radioactive contamination of transport vehicles, environment, and detection of ionizing radiation sources in different technological and production processes.

PRINCIPLE OF OPERATION: detecting NRM X-rays and gamma radiation in the range 40 to 3000 keV on the natural background, which is measured and taken into account during signal analysis.

COMPONENTS: power and control unit (PCU), 1 to 8 detection units (DU) and set of connection cables.

SPECIFICATIONS
 
Detection threshold (for one DU, 3 s monitoring time at the distance of 50 cm from DU)  
Nuclear materials (g) 1,8 (U-235); 0,15 (Pu-239)
Radioactive materials (kBq) 87 (Co-60); 102 (Cs-137);
70 (Am-241); 107 (Ra-226)
For gamma radiation exposure rate exceeding the background, (μR/h) 12 (Co-60); 3,4 (Cs-137);
0,47 (Am-241); 10,8 (Ra-226)
Range of monitoring time adjustment 0,2 - 100 s
False alarm frequency 1 per 1000 passages
Power supply Mains 220 V AC, 50 Hz, 30 W
Continuous operating time unlimited
Operating temperature range -40 to +50
Weight of the detection unit no more than 2.5 kg
Weight of the power and control unit no more than 5.4 kg
Detection unit dimensions 3706060 mm
Power and control unit dimensions 310265130 mm

FEATURES:

  1. The number of detection units (from 1 to 8) and the distance between them can be selected on the basis of the existing configuration of the monitoring area, detection threshold and NM type.
  2. Due to small dimensions of the detection unit and the structural flexibility of the TSRM61 it is possible to install the TSRM61 at checkpoints of any type easily and quickly, including those being in operation; it is also possible to equip doorways, conveyer belts, etc.
  3. RS485 (RS232) Interface allows using TSRM61 jointly with other systems.
  4. Audio, digital and light indication provides for easy setup and off-line operation.
  5. The software allows adjusting detection sensitivity on site.
  6. The monitor has the conformance certificate.
