Abstract
A prototype scintillation spectrometer capable of measuring low energy phot ons from transuranic elements in groundwater has been developed for in situ applications. The detector is a CaF2 (Eu) crystal enclosed in a stainless steel casing with a 19 mg.cm(-2) stainless steel entrance window. Evaluatio n of the system was performed in the laboratory by submersing the probe int o a number of aqueous solutions containing varying concentrations of Am-241 in a simulated well environment. Spectra obtained had easily discernible p eaks associated with the low energy L X-rays and the 60 keV gamma-ray photo peak of Am-241.
