EVALUATION OF A DIRECT EXTRACTION LIQUID SCINTILLATION-COUNTING TECHNIQUE FOR THE MEASUREMENT OF URANIUM IN WATER

An extraction procedure utilizing alpha liquid scintillation was evalu ated for the rapid determination of uranium in aqueous environmental s amples. The extraction efficiency of the system was measured under var ying chemical conditions including pH. The procedure was evaluated aga inst a traditional radiochemical technique using both laboratory prepa red control samples and actual groundwater. Finally, the possibility o f obtaining isotopic information from the liquid scintillation spectra was also investigated using a curve fitting routine.
