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