a.
The error values for all radionuclide listed except 90¢), 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 a single sample plus an
analytical error.
b.
ns = not significant; the net sample count is less than the two-sigma, propagated, counting error.
