Abstract: | Researchers from the Savannah River Technology Center, the Center for Applied Isotope Studies (CAIS) and Sampling Systems
have developed a prototype Field Deployable Tritium Analysis System (FDTAS) for near-real-time measurements of environmental
levels of tritium in ground and surface water. The device consists of a modified liquid scintillation counter coupled to an
automatic sampler which incorporates on-line water purification. The FDTAS has been field tested at several Savannah River
Site locations and has produced results comparable to laboratory analyses for low concentrations of tritium. Figures of merit
obtained in the field include an average tritium background count rate of 1.5 counts per minute (cpm), tritium detection efficiency
of ≈25%, and a detection limit of <10 Bq/l for a 100 minute count. |
