Irradiador Gamma con Soporte de Calibración UDG-AT110

UDG-AT110AT110 Gamma beam irradiator with calibration bench is designed for verification, calibration and examination of ionization radiation measurement instruments in collimated field of gamma radiation.








Operating principle

Irradiator based on the use of radionuclide sources of 137Cs.

The installation scheme is realized with a fixed irradiator and linear-positioned platform of calibration bench.
The range values ??of dose rate of gamma radiation is achieved by using different sources of 137Cs with different activity and changing in the distance "a source-detector".

Sizeof the radiation field varies by distance "a source-detector" or diameter collimator channel.
The positioning of calibrated equipment in the collimated gamma beamis provided by the calibration stand.
Management function of the stand is carried out by means of software and portable control panel.



  • Metrological assurance of gamma radiation dosimetry:
    • Laboratories for research, adjustment and serial production of dosimetric instruments
    • Metrology laboratories focused on calibration and verification of dosimetric instruments
    • Secondary standard dosimetric laboratories (SSDL)


  • Up to 5 gamma sources in irradiator protection container
  • Software, motion control sources in theirradiator
  • Automatic and manual positioning
  • Movingsources in the irradiator and the moving platformusing digital servos
  • Centering the reference and calibrated equipment using laser systems
  • Remote monitoring the indicated value of calibrated instruments using video surveillance system
  • Safe braking and travel limitation of movable platform
  • Lock system and visual alarms of source position
  • Continuous control of radiation environment
  • Emergency power sources
  • Download the sources in the installation using transferring container and accessory set
