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