Determination of mass attenuation coefficients of dilute solutions of sulphates of some elements

The narrow beam transmission methods have been employed for the determination of linear mass attenuation coefficients of the aqueous solutions of some sulphates of alkaline earth elements in the concentration range 0.05 to 0.25 g/cm3 at 81, 356, 511, 662, 1173 and 1332 keV gamma ray energies. From the precisely measured densities of these solutions, mass attenuation coefficients were then obtained. These coefficients were then successfully used to determine the effective atomic numbers of the solutions. A very good agreement is observed between the theoretical and experimental values. (author)
