Covering of Contaminated Surfaces cont'd - doe-hdbk-1106-97

DOE-HDBK-1106-97

Instructor's Notes

If it is likely that contamination exists under a painted surface,

it may be necessary to remove some of the painted surface to

measure contamination levels below. Use a paint remover to

collect paint samples from areas of approximately 200 cm2 .

Measure alpha and/or beta-gamma levels beneath paint. Check

with Radiological Control personnel prior to using any paint

remover to eliminate the generation of mixed waste.

Where potentially contaminated surfaces are not accessible for

measurement, the equipment may be released after case by

case evaluation and documentation based on both the history

of its use and available measurements demonstrate that the

unsurveyable surfaces are likely to be within the release

criteria.
