GammaLab Virtual Laboratory

  • Виртуальная лаборатория GammaLab


GammaLab software package is used for imitation of measurement process of gamma radiation sources by semiconducting and scintillation spectrometers.
GammaLab is a virtual gamma spectrometry laboratory, instrumented by measuring equipment, software for spectrometers operations, calibration sources and samples for measurement. It is used for the courses for advanced training “Practical spectrometry”.

GammaLab contains modules for emulation of spectrum accumulation in the analyzer from the measured source of radiation in real-time mode. It also includes operator’s measurement actions. The measurement operator’s actions on the desktop can be emulated using realistic 3D-interface:

  • moving of the detector and the source;
  • control of the spectrometer’s parameters (switching on/off, switching on of the high voltage, error messages of the device etc.);
  • operations with the software of the spectrometer.

GammaLab allows to:

  • model gamma spectra in real-time mode for semiconducting and scintillation detectors, point and volume cylindrical sources, sources in multi-layer protective container with arbitrary radionuclides composition;
  • use arbitrary chemical mixtures as materials;
  • take into account the location of the samples and detector and instrumental effects (peaks tailing and shift, miscount depending on loading, voltage, time of the device warm-up and high-voltage supply).


  • for apparatus calibration;
  • for development and testing of measurement procedures and software;
  • as a base of emulators;
  • for training in work with spectrometers;
  • as a reference-information system;
  • for analysis of applicability of new detecting devices.

There are many advantages of using of modeled spectra for development and testing of measurement procedures and software:

  • there are no out-of-control instrumental effects in the hardware spectra;
  • these effects can be considered in the model;
  • the sources with the required radionuclides composition and activity values can be modeled;
  • both calibration spectra and spectra of the measured samples with the required properties (density, material) can be modeled uniformly.
