The error values for all radionuclide Visted except 90Sr and Pu are tyo-sigma, propagated, counting errors for a single sample. The error value for 7¥Sr and Pu is the two-sigma counting error for a single sample plus an analytical error. : i b. c. Analyses performed by McClellan Central Laboratory, Sacramento, California ns = not significant; the net sample count is less than the two-sigma, propagated, counting error. \ d. Analyses performed by LRE. ‘ v9 na = not analyzed.
