Field demonstration of technologies for characterization of uranium contamination in surface soils
One means of improving the efficiency of studies associated with CERCLA and RCRA investigations of. sites contaminated with uranium is to introduce new field screening technologies capable of quickly delineating the contamination distribution in surface soils. To this end, the performance of four technologies suitable for field measurement of uranium concentrations in soils was evaluated at the Fernald Environmental Management Project. The four technologies tested were high-resolution gamma spectroscopy, wide-area beta scintillation counting, laser ablation-inductively coupled plasma-atomic emission spectroscopy (LA-ICP-AES), and long-range alpha detection (LRAD). The performance of each technique was assessed by comparing of the results obtained in the field and by comparing the field measurements to data obtained from laboratory analysis of soil samples
