The data from an interlaboratory collaborative test are presented. A statistical analysis of the data is also presented. From that analysis, statements are made of the combined within-laboratory precision, the systematic error between laboratories, the total error between laboratories based on a single analysis, and the method bias. Soil samples used for the test contained plutonium in a highly refractory form, a very insoluble form, and therefore, difficult to measure the true concentration. Plutonium concentrations in those samples ranged from 0.1 to 10 dpm/g of soil. A comparison is made between the acid dissolution method and a fluoride-pyrosulfate fusion method which was tested in a similar study using the same test samples.
