a.

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.

b.

ons = not significant; the net sample count is less than the two-sigma, propagated counting error.
na = net analyzed.
