FIELD: technology for quantitative estimation of radio nuclides by means of method of scintillations in liquid, in particular, composition of cocktails from measurements by method of scintillations in liquid, useable for direct preparation and calibration of standard radioactive samples of large amount of radio nuclides without preliminary processing. ^ SUBSTANCE: proposed cocktail for measuring scintillations in liquid contains: two solvents, one which is aromatic and another one is polar; admixture for increasing light recovery; two scintillator parts, one of which is primary and other one is secondary; extracting agent; at least one ionic or non-ionic surfactant. ^ EFFECT: provision of stability of liquid scintillator, possible usage thereof for measuring direct count of radiation impulses from different radio nuclides. ^ 11 cl, 3 tbl |
