Energy technical light output of scintillators – problems of assessment and an alternative method for their solution

The paper analyzes the problems that arise when assessing energy technical light output by existing methods. A modern alternative method for of various scintillators produced Institute Scintillation Materials National Academy Sciences Ukraine is described.
 possibility evaluating any scintillator relative comparison with a reference stilbene-based known shown. resulting ratio responses recalculated in ph/MeV taking into account scintillator, equal to 0.023, and photon formation particular scintillator.
 estimation procedure described. Expressions are given calculating values yield stilbene units ph/MeV. radioluminescence spectra tested compared sensitivity normalized laboratory photodetectors.
 based on single crystals NaI(Tl), CsI(Tl), CWO, BGO, p-terphenyl, anthracene, stilbene, plastic has been estimated. amplitudes ratio, spectral normalization coefficients were obtained To check adequacy calculation inorganic absolute was carried out using collection literature.
 It shown an increase output, units, from 0.26 BGO 4.3 their increases 2500 33100 decrease scintillation 2.988 (l = 415 nm) NaI(Tl) 2.214 560 CsI(Tl) also latter 35300 performed estimates accuracy 8%.
