This report provides results of the two-round nationwide in vitro bioassay intercomparison study. Conclusions were based on analyses by 35 bioassay laboratories of nearly 1400 artificial urine samples containing known quantities of radionuclides. The test radionuclides were H, /sup 89/Sr, /sup 238/Pu, /sup 241/Am, /sup 137/Cs, /sup 60/Co, and natural uranium. The data reported included background count rates, total samples counts, counting times, counting efficiencies, sample yields, and estimated errrors of the determinations. The measurement data were evaluated according to statistical methods presented in the November 1985 version of the draft ANSI Standard N13.30. If a laboratory failed a performance test for any one of the three criteria, the laboratory was considered to have failed the test for that category. 22 refs., 18 figs., 14 tabs
