Study of errors using scintillation spectra unfolding for the calculation of photon field dosimetric characteristics

Unfolding technique makes it possible to reconstruct the incident photon spectra from the spectra, measured by the scintillation spectrometer and calculate dosimetric quantities of the measured photon fields. MC simulation of the detection system matrices and used unfolding method are presented as well as examples of the experimental spectra analysis results. Uncertainties and reproducibility of the dosimetric quantities calculated by the unfolding process was tested and analyzed.
