De Lange, P W

The application of a new radiometric method for the analysis of uranium-- thorium ores is discussed. This method, referred to as the beta -- gamma -- gamma --method, does not rely on the fortuitous equality of some apparatus constants, but is a combinaiion of the beta--gamma ( beta -- gamma ) method and the gamma --discriminaiion method ( gamma -- gamma ) to obtain per cent U/sub 3/ O/sub 8/, per cent ThO/sub 2/, and the equilibrium value of thie uranium series. The minimum concentraiions that can be determined are 0.005% U/sub 3/O/sub 8/ and 0.005% ThO/sub 2/ in mixed naturaily leached are using 90 gram samples. Results obtained with the beta -- gamma -- gamma , beta -- gamma , and gamma -- gamma methods are compared. The influence of different standards on the results is discussed. (auth)
