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.
