Determination of gamma-spectrometric parameters for some chloride salt solutions

The mass attenuation coefficients, atomic cross-sections and effective atom ic numbers are determined for LiCl, NaCl and KCl solutions with contents up to 0.2 g cm(-3). The energies used are 0.511, 0.662 and 1.274 keV. The com bined results were employed to determine the mass attenuation coefficients and atomic cross-sections of the salts and water in the solutions. The resu lts are compared with the calculated values from elemental data. It was fou nd that the mass attenuation coefficients and corresponding total cross-sec tions are, in general, less from measurement than from tabulated data, eith er for water or for the chloride salts.
