a.

The error values for all radionuclide listed except 90sy and Pu are two-sigma , propagated, counting errors
for a single sample. The error value for 90Ssr and Pu is the two-sigma counting error for a single sample
plus an analytical error.

b.

Analyses performed by McCleltan Central Laboratory, Sacramento, California

c.

ns = not significant; the net sample count is Tess than the two-sigma, propagated, counting error.
