Gamma-spectrometric determination of natural radionuclides and 137Cs concentrations in environmental samples. The improved scintillation technique

We propose a new technique for approximation of spectral components of environmental samples with the spectra of standard sources 226Ra, 232Th, 40K, 137Cs and inert samples. This method allows to noticeably increase the preciseness in the determination of radionuclide composition of samples.
