UDG-1B: noble gas monitor

UDG-1B: noble gas monitor

Continuous automatic monitoring of the beta-emitting radioactive gases concentration in the working air and in the air in ventilation ducts and stacks.
  • Gamma background compensation
  • Audible and visual alarm signals of the excess of preset thresholds
  • Periodic calibration by means of standard beta- source

Pump unit BN-01
Pump unit is ensures air sampling by feeding the air from work places and/or ventilation systems to the aerosol and gas monitors.
BI-2: External display & alarm unit
  • Display of data received from equipment of Automated Radiation Monitoring System (ARMS)
  • Audible and visual alarms on exceeding preset thresholds of the ARMS equipment
  • individual threshold setting for each measurement channel
  • Audible alarm: 80-100 dB at a distance of 1 m
  • Visual alarm: red, yellow, green
BAS/BAS-1s: external alarm
Generation of audible and visual signals of the excess of preset thresholds RMS monitors
External display unit
Display of data received from equipment of Automated Radiation Monitoring System (ARMS)

Software "Configurator"
"Configurator" may be used for testing, configuration, calibration, data analysis, optimization and graduation devices. The program supports the following device: BOP; UDA-1AB; UDG-1B; BOP-1S; BOP-1M, DKG-09D, MKS-17D.
With the help of the "Configurer" you can read the information about the internal state of the device, display information about possible errors and failures in his work, tune individual settings or switch his mode of operation. In addition, you can delete archived data measurements and workers spectra for further analysis.
SKGAV: stack monitor
Continuous monitoring of radioactivity in gaseous effluents
  • Automatic monitoring of the alpha- and beta- radioactive aerosol, noble gas and radioiodine concentrations in the air in ventilation ducts and stacks
  • Monitoring of the flow rate, temperature and humidity of the gas flow
  • Separation of gaseous effluent into targeted fractions by means of a two-stage filter
  • Reversion of gas after analysis to the ventilation system
Radiation monitoring system (RMS) "Pelikan"
The RMS "Pelikan" is installed and operating at about 20 facilities representing different industries, at three research reactors, two nuclear power plants and aboard the ice-breaker "50 Years of Victory".
