Abstract;The precision of a radiochemical measurement can be estimated from Poisson statistics, detecting errors by comparing observed with expected precision. A good way to test measurements is to strive for high accuracy. We recently determined 90 mg of arsenic in silicon by INAA with an expanded uncertainty of 0.38%. This measurement meets the CCQM definition of a primary ratio method. (author abst.)
