The Eastern Environmental Radiation Facility's Participation in Interlaboratory and Intralaboratory Comparisons of Environmental Sample Analyses: 1979 and 1980

摘要

Since 1964 the Eastern Environmental Radiation Facility (EERF), Office of Radiation Programs (ORP), U.S. Environmental Protection Agency, has compared its results of analyses of radionuclides in environmental and biological samples with those of other agencies. Such intercomparisons are sponsored by several agencies and the results are routinely published by the quality assurance reference center of the respective sponsoring agency. All samples in these intercomparisons are treated anonymously, identified by a code known only by the originating laboratory and appropriate reference center. This report presents our results for 1979 and 1980 in intercomparison studies sponsored by EMSL-LV, WHO, and the IAEA as well as our intralaboratory analyses results. The latter results include replicate, blind, and spiked sample analyses. The authors plan to publish similar reports on a biannual schedule.
