Abstract

In 1997, the Department of Energy, Office of International Health Programs(EH-63) contracted the National Institute of Standards and Technology (NIST)to perform an intercomparison to evaluate state-of-the-art analysis techniquesfor 239Pu in synthetic urine in µBq quantities. Sample preparationwas performed by Yankee Atomic Environmental Laboratory. Five replicate samplesat spike amounts of 3.7, 9.26, 29.6, and 55.6 µBq and a blank amountwere distributed to the participating laboratories in 200 g of synthetic urine.Los Alamos National Laboratory (LANL) participated in the intercomparisonusing thermal ionization mass spectrometry (TIMS). LANL results, system improvements,and future intercomparisons are discussed.
