A Remotely Operated, Field Depolyable Tritium Analysis System for Surface and Ground Water Measurement

摘要

A prototype system for the remote, in situ analysis of tritium in surface and ground waters has been developed at the Savannah River Site through the combined efforts of university, private industry, and government laboratory personnel under a project funded by the U. S. Department of Energy. Using automated liquid scintillation counting techniques, the Field Deployable Trititum Analysis System (FDTAS) has been shown in laboratory and field tests to have sufficient sensitivity to measure tritium in water samples at environmental levels (10 Bq/L (approx270 pCi/L) for a 100-minute count) on a near-real time basis. The FDTAS consists of a fixed volume sampler (50 mL), an on-line water purification system, and a stop-flow liquid scintillation counter for detecting trititum in the purified sample. All operations are controlled and monitored by a remote computer using standard telephone line modem communications. The FDTAS offers a cost-effective alternative to the expensive and time-consuming methods of field sample collection and laboratory analyses for tritium in contaminated groundwater.
