Project Overview
The objective of this project is to apply high-pressure gamma-ray
spectrometer technology to a probe that is compatible with a cone
penetrometer (CPT) system for in-situ characterization of radioactive
waste sites. The probe is intended as an improved, direct replacement for
currently used sodium iodide detectors, which suffer from energy resolution
limitations that make it very difficult to resolve individual radioactive
species in a mixed contaminant environment. Xenon spectrometers also avoid the
operational issues associated with solid-state charge conversion detectors,
such as germanium, which requires active cooling within the rigid constraints
of a CPT probe.
