摘要：

Experimental results are provided for the sample analyses for technetium in charcoal samples placed in-line with a Savannah River Site (SRS) processing stack effluent stream as a part of an environmental surveillance program. The method for Tc removal from charcoal was based on that originally developed with high purity charcoal. Presented is the process that allowed for the quantitative analysis of Tc-99 in SRS charcoal stack samples with and without Tc-97 as a tracer. The results obtained with the method using the Tc-97 tracer quantitatively confirm the results obtained with no tracer added. All samples contain Tc-99 at the pg.g(-1) level.
