  ABSTRACT: Alpha spectrometry using pulse height analysis has been used for the determination of uranium concentrations in different environmental samples. The concentration of 238U was measured by both destructive and non-destructive techniques with a detection limit of less than 1.8 mBq/kg. However, because of the extremely low 234U concentrations in environmental samples, it was necessary to use a destructive technique to separate U from the sample matrices as well as remove interfering elements from the sample solution to determine 238U/234U ratio. In this study, the uranium was separated from the environmental samples using anion exchangers in (Dowex 1 × 8 Cl? form) and purified via co-precipitation with Lanthanum fluorides (LaF3) and the alpha source prepared by electrodeposition. The results obtained were validated using some certified reference samples.
