Smear Surveys for Releasing Material

1. An initial screening evaluation may be conducted by

wiping 100 percent of surface.

2. These large-area wipes may be evaluated by holding

the probe up to the swipe (~5 sec.).

3. If initial screening evaluation indicates presence of

contamination, take representative disc smears (100

cm2 spill area) of up to 100 percent of accessible

surface areas.

Documentation
