Series Description: This series consists of computer-generated reports, worksheets, and raw data relating to tritium sampling at various onsite and offsite locations. Sampling data include identification numbers, QIP [Quality Improvement Process] measurements, readings in picocuries per cubic meter and milliliter, weights, readings in DPM [disintegrations per minute], decay days, background readings, and average efficiencies. Computer-generated reports found in Accession Number TBF181 record the percentage deviation between CPMA/K, CPMB/K, and CPMC/K [counts per minute at three different locations, or windows, labeled A, B, and C by a user-controlled constant labeled K]. A second type of report found in the same container notes ESR [External Standard Ratio], EFF [effluents], counts per minute, and the concentration of tritium in picocuries per milliliter. Sample types are not specified, although there are indications that samples included air and water. Samples were collected from onsite buildings and several offsite locations, including Arvada, Boulder, Broomfield, and Walnut Creek, Colorado.
