that uranium contamination may be located
in areas not a ccessible t o survey.
DOE requires that materials used in
Contamination Areas, High Contamination
Areas, and Airborne Radioactivity Areas
that are being released for unrestricted use
have accessible surfaces surveyed.
Materials with inaccessible surfaces having
a potential for internal contamination shall
not be released without evaluating the
material on a case-by-case basis to ensure
internal contamination does not exist.
DOE value s for rel ease of u ranium-
contaminated materials are higher than
DOE values for release of materials
contaminated with some other radioactive
nuclides found in the DOE system, such as
plutonium. The difference in these values
is due to the relative health risk from
exposure to uranium contamination
compared with these other nuclides.
