The error values for all radionuclides listed except 99Sr and Pu are two-sigma, propagated counting errors for a single sample. The error value for 90Sr and Pu is the two-sigma counting error for 90 Sr and Pu is the two-sigma counting error for a single sample plus an analytical error. _ b. ons = not significant; the net sample count is less than the two-sigma, propagated counting error. not analyzed. ~~
