ANALYTICAL METHOD FOR THE DETERMINATION OF NON-URANIC ALPHA EMITTERS IN URANIUM PRODUCTS FROM THE REPROCESSING OF NATURAL URANIUM FUELS

摘要

The alpha emitters are co-precipitated on lanthanum fluoride and the alpha activity of the precipitate measured with an alpha scintillation counter. The proportion of this activity originating from non-uremic alpha emitters is determined by alpha pulse height analysis.
