Evaluation of a Technetium-99 Detector Based on Laboratory Testing for Use in In-Situ Vadose Zone Applications

摘要

This document evaluates the feasibility of in-situ detection of technetium-99 in Hanford Site vadose zone soils (the soils between the surface and groundwater) using laboratory tests. The detector system performs adequately for high technetium concentration, but more development and laboratory testing is needed before field demonstration is performed.
