    Precision processing of spectra
    Spectra processing algorithms, used in SpectraLine package, consider the specifics of the spectrometers. The sequence of the processing operations, including reading of different spectrum formats, integration with external hardware etc., can be represented as a scenario, so the user can widely adopt the algorithms to the used hardware.

    Database
    The selected spectra and activity calculation results can be stored in the database of SpectraLine software package.

    Reports with measurement results
    Mass concentration, dose, MDA etc. are displayed in the customized window with calculation results. The user can create their own reports patterns.

    Scenarios
    There is an extended list of commands of the scenarios in SpectraLine software package. The complex schemes of measurement and processing of samples, spectrometer calibration, background measurement, nuclear analysis and other spectrometry tasks can be realized.

    Materials database, absorption consideration
    • • Database with absorption values of gamma-radiation in different materials on the base of Photon Cross Sections Database (http://www.nist.gov/pml/data/xcom/index.cfm) is used in the software. So the absorption can be calculated with high precision and the reliability of the processing results is increased.
    • • The utility for the materials database editing is included into the delivery kit.
    Joint measurements of gamma- and beta- spectra
    The function of the joint measurement and processing for two-channels beta-gamma-spectrometers is added, so their using is simplified and precision of activity calculation is increased, especially for beta-emitting radionuclides.

    Modes
    Operations can be performed in operator-administrator mode. The functions of measurement and processing of the sample can be only available in operator mode. The processing settings and expert settings can be protected by password.

    Start with parameters
    The command line parameters are supported in SpectraLine software package so the processing scenarios can be run at the software start.

    External programs
    Peaks search results can be transferred to external user programs for continuous processing. External programs can be used in SpectraLine software package as an additional instrument for user methodologies realization for the specific spectrometric tasks.

    MDI GUI interface
    MDI GUI interface which is uniform for all SpectraLine programs: spectrum is displayed in a separate window with approximating function and processing results. The spectrum can be scaled, shifted; the scale and custom color palette can be changed; several spectra can be viewed in the same window using comparison mode; the ratio of counting number deviation from approximating curve to counting number uncertainty can be displayed.

    Special reports based on standards of radionuclides content in different environments
    • measurement protocols for typical certified measurements including safety norms of natural radiation sources (sanitary regulations 2.6.1.2523-09);
    • sanitary and epidemiological rules and safety norms of provision (sanitary regulations 2.3.2.1078-01);
    • sanitary and epidemiological rules and safety norms of forest management production (sanitary regulations 2.6.1.759-99);
    • hygienic norms about technogenic radionuclides content in metals (hygienic regulations 2.6.1.2159-07).
    State Registration
    SpectraLine software was registered in the State Register for computer programs on the 29th of May 2014..

    What’s New

    Calibration by orthogonal polynomials
    Energy and FWHM calibrations using orthogonal polynomials have been developed in SpectraLine software package. The more precise description of energy- (FWHM-) channel dependency for each spectrometer type is obtained by the range separation into several zones and by calculation of the calibration curve of the required degree by reference points. Furthermore, the uncertainty corridor is calculated.

    CdZnTe spectra processing



    The algorithms of CdZnTe spectra processing are optimized for the line form consideration.

    Quality assurance system


    The quality assurance system of SpectraLine provides monitoring of the spectrometer channel for the parameters of the total absorption peak for the specified energy and the background count rate. So the reference sample and the background are measured in semi-automatic mode. As the scenarios are used the measurement parameters can be flexibly adjusted and the monitoring results can be displayed depending on the date and time of the measurement start.
    The control bounds determined by the alarm and warning levels are displayed in the graph, so the parameters deviation from the specified intervals can be easily found.



    Distributed expert system organization
    The distributed expert system for measurements and results analysis can be created using several spectrometers with SpectraLine software in the "Operator" mode and expert PC. The "Operator" mode provides spectra acquisition and automatic processing. SpectraLine in "Administrator" mode is installed on the expert PC for spectra processing in interactive mode. The spectrum measured by operator is sent via e-mail to the expert PC for the detailed analysis.

    Nuclide Master Plus integration
      



    For the detector, model of which is set in the configuration parameters, and the geometry set in the spectrum properties window, the detection efficiency can be calculated using Nuclide Master Plus software.

    Continuous monitoring of hardware connection

    According to the color indicator on the icon for the analyzer window opening the connection status of the device can be seen: the analyzer is connected, the analyzer is not connected, there is no dynamic library for the device connection or the device is disabled in the configuration.


    Several spectra saving in one file
    Several spectra (as well as several background spectra) can be saved in one file and the background can be selected depending on the geometry.

    Radionuclide vector
    The method is used to improve the accuracy of activity measurement and to estimate the activity of the nuclides for which the activity measurement is difficult.

    Measurements journal
         

    For each configuration in automated mode the measurement journal is maintained and the measurements reports are generated for the spectra added to the journal.
    The spectrum can be processed after acquisition and it can be saved on the disk. The spectrum data will be saved in the journal. The measurement report containing spectrum processing parameters is generated at the moment of saving. If a report is created at the spectrum processing it also is saved in the journal.
    If a spectrum has been acquired earlier it also can be added to the journal.


    Stereo measurements
    The activity distribution of complex objects can be measured and obtained using LSRM Ltd software.
    This procedure conceptually consists of two steps: measurements under the scheme and joint processing of a set of spectra.
    The scheme consists of a set of steps (serial or parallel) for operator to get data required for the calculation. Spectra are measured in the measurement points which are set in the pre-created scheme if an object should be measured. This step is implemented in Shiva application.
    Joint processing, which is an option of 1.6 version, is performed for all the spectra of the sample, it takes into account the contribution of the activity of each part of the complex sample and it provides the calculation and distribution of sum activity.

    Optimization of spectrometer background consideration methods
    The following methods of background consideration are supported in SpectraLine software package:
    • the sample spectrum correction – the background subtraction by channels which is the correction of counts of sample spectrum in each channel;
    • modification of the procedure of background subtraction by channels – the subtraction of the background counts of peaks only;
    • the spectrum markup with background lines setting, which are approximated using their a priori values of count rate.
    Apparatus peaks calibration


    The peaks, which correspond to the energy partial absorption (single and double escape peaks, the peaks of gamma-radiation back scattering outside the detector and the peaks of “side” scattering if the reflection is performed with angles which are less than 90°, and not with angles of 180°, usually from the surfaces to the side of the detector), are considered. A priori values of such peaks areas are set for mono-lines and they are further interpolated by the nearest points.
