SCO Wipe Efficiency and NUREG-1608

["Key, James" <JFK6@pge.com>]

This is a continuation of an earlier posting dealing with surface
contaminated objects (many thanks to those replies).

In the NRC IE Information Notice 85-46 there is a discussion of higher
efficiency wipe samples.  This raises several questions:

- What wipe efficiencies do you assume for painted/unpainted concrete/metal?

- If you assume a wipe efficiency greater than 10%, what technique do you
use and how do you defend the higher efficiency value?

An earlier reply to my posting concerning SCO's indicated that NUREG-1608
had been released.  It does not appear to have been posted anywere on the
Internet, but is available through NTIS (800-553-6847) as NUREG-1608INZ for
$27 + $5 handling.

Thank you in advance,
