The error values for all radionuclides listed except 90Sr and Pu are two-sigma, propagated, counting errors for a
single sample. The error value for 90 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 error.
na = not analyzed.
