“…Perhaps the 5 cm was really the radius and the 25 cm depth should have read 2.5 cm (i.e., 10 cm in diameter and 2.5 cm deep as noted below). The term "cookie cutter" was accurate, however, because even today the soil sampling tool is referred to as a "cookie cutter," in obvious reference to the original cellulose tape container noted by Corley et al in 1971.…”

“…Testing Co., Inc. (e.g., as reported by Corley et al 1971) were obtained by extracting and isolating the plutonium from the sample, electroplating it onto a stainless steel disc, and then exposing the disc to photographic film. The number of alpha tracks recorded on the film (produced by all isotopes of plutonium present) were counted by visual inspection with a microscope, converted to picocuries per unit of sample (pCi/g), and reported(").…”

“…Testing Co., Inc. for bioassay samples that were reported as total plutonium. Some of the early plutonium soil analyses (also reported in Corley et al 1971) were analyzed in laboratories operated by PNNL and utilized a similar extracting and isolating technique. However, the resulting solution was evaporated onto a stainless steel disc and counted electronically with a silicon surface-barrier detector to determine the isotopes of (a) Each alpha track was created by one disintegration of a plutonium atom.…”

Historical review of long-term soil sampling for environmental surveillance at the Hanford Site and vicinity

Soil samples have been collected routinely from the environs of the Hanford Site and analyzed since 197 1. Correct interpretation of results depends on samples being collected from the same locations, the locations remaining relatively undisturbed, and collection and analytical procedures remaining the same or being equivalent. Historical files, documents, and annual environmental reports were reviewed to evaluate these factors. It was determined that 20 soil sampling locations, 11 onsite and 9 offsite, were established between 1971 and 1977 and represent long-term sampling locations. Sample collection and analytical procedures have remained essentially the same since 1971. The physical and ecological attributes of each long-term soil sampling location were evaluated. During the review of historical records, a few results for 1970, 1971, and 1972 were noted as previously unreported in annual or special reports. These results are included in Appendix A. To complete the record, results previously reported in annual environmental reports are given in Appendix B. Global Positioning System .(GPS) readings for 20 long-term soil sampling locations are provided in Appendix C.

“…Surface soils near the Hanford chemical separations and waste management facilities (200 Areas) are known to contain slightly higher concentrations of 239-240pu than other locations, both onsite and off (Corley et al 1972). Also, very small quantities of 241Am could occur in local surface soils from the release of trace amounts of 241Am or 241pu from the PUREX facility during the years of fuel reprocessing (1956 to 1972).…”

Various kinds of surface soil samples were collected and analyzed for Americium-241 (241Am) to examine the feasibility of improving soil sample data for the Hanford Surface Environmental Surveillance Program. Results do not indicate that a major improvement would occur if procedures were changed from the current practices. Conclusions from this study are somewhat tempered by the very low levels of 241Am «0.10 pCi/g dry weight) detected in surface soil samples and by the fact that statistical significance depended on the type of statistical tests used. In general, the average concentration of 241Am in soil crust (0 to 1.0 cm deep) was greater than the corresponding subsurface layer (1.0 to 2.5 cm deep), and the average concentration of 241Am in some onsite samples collected near the PUREX facility was greater than comparable samples collected 60 km upwind at an offsite location.
