The linear attenuation coefficients in aqueous solutions of some chlorides and sulphates, viz. MgCl2. 6H(2)O, CaCl2, SrCl2. 6H(2)O, BaCl2. 2H(2)O, Na2SO4, K2SO4 and MgSO4. 7H(2)O were determined at 81, 356, 511, 662, 1173 and 1332 keV by the gamma -ray transmission method in a good geometry setup. From the precision measured densities of these solutions, mass attenuation coefficients were then obtained which varied systematically with the corresponding changes in the concentrations (g/cm(3)) of these solutions. A comparison between experimental and theoretical values of attenuation coefficients has shown that the study has potential application for the determination of attenuation coefficients of solid solutes from their solutions without obtaining them in pure crystalline form.
