a.
The error values for all radionuclide Visted except 90Sr and Pu are tyo-sigma, propagated, counting errors
for a single sample. The error value for 7¥Sr and Pu is the two-sigma counting error for a single sample
plus an analytical error.

Analyses performed by McClellan Central Laboratory, Sacramento, California
ns = not significant; the net sample count is less than the two-sigma, propagated, counting error.
