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 90Sr 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-siqma, propagated counting error.
