Aikin, A M; Bruce, T

The LaF/sub 3/ method for determining plutonium was investigated and found to give results below 95% of true value. The self-absorption of alphas in Pu sources containing U was measured as a function of U concentration. The absorption reaches 5% when the source contains 500 mu g of U. Hence for solutions of Pu and U better accuracy is obtained if the solution is alpha counted directly and corrected for self-absorption than if the Pu is separated by LaF/sub 3/ precipitation and counted on the La precipitate. The precision decreases as the amount of U on the source increases. (auth)
