Selective detection of uranium by laser-induced fluorescence: a potential remote-sensing technique. 2: Experimental assessment of the remote sensing of uranyl geologic targets.

An analysis is presented of a method to detect selectively uranyl ion fluorescence from geologic targets. Limitations to the sensitivity which are imposed by system parameters and noise sources are discussed. A ground-based laser system designed and constructed as part of this study is described, and data obtained with this system are presented. Finally the operating criteria of a conceptual airborne system for regional mapping of uranyl fluorescence anomalies are considered.
