Abstract: | Titanium and calcium in ceramic materials can be analysed by neutron activation using a number of radioisotopes. Historical usage of scandium-47 for the analysis of both elements is reviewed. Measurements were made of the production and decay of 47Sc sources prepared by SLOWPOKE reactor irradiations of pure titanium and calcium salts. Relative interferences were established and their effects calculated for a range of ceramic types. This study indicates that published values of the concentrations of titanium and calcium, using 47Sc, must be seriously reassessed. |
