The main features:
  • spectrometric measurements and precision processing of gamma-spectra; the processing involves calibration, peaks parameters searching, radionuclides identification, activity calculation and account for true coincidence factors for further gamma-radiation intensities correction;
  • spectrometric analysis with using of semiconducting and scintillation gamma-beta-spectrometers;
  • identification and activity calculation of open sources and sources in transport containers using portable gamma-radiation semiconducting and scintillation spectrometers; calculation of the protective layer thickness;
  • analysis of nuclear materials, determination of Pu samples isotopic composition and U samples enrichment level;
  • analysis of unidentified lines using identified nuclides lists, using user’s list and using full radionuclides database (based on ENSDF); radionuclides filtration by half-decay period, energy spectrum etc.; decay chains analysis, escape peaks and peaks of true and random coincidence analysis.
  • quality assurance system;
  • measurements journal.
The following demonstration configurations are included in SpectraLineUltimate:
  • for typical HPGe detector;
  • for beta radiation scintillation spectrometer;
  • for HPGe detector;
  • for detector based on LaBr3(Ce) crystal;
  • for gamma radiation scintillation spectrometer with NaI crysta;
  • for coaxial detector with Pu spectra;
  • for planar detector with Pu spectr;
  • for coaxial detector with U spectra;
  • for planar detector with U spectra.
