4.0 Volume Contamination

EH-412 has provided guidance for release of material that

has been contaminated with tritium (reference DOE 1995).

Other materials may be released if criteria and survey

techniques are approved by DOE.

5.0 Items With Fixed Contamination

Under exceptional conditions, materials and equipment with

fixed contamination that exceeds the release criteria may be

released for use in Controlled Areas outside of Radiological

Areas. As a condition of such release, the removable

contamination levels must be below the level specified in

Appendix D of 10 CFR 835. The materials shall be

routinely monitored, clearly labeled and/or tagged to alert

personnel of the contaminated status, and have appropriate

administrative procedures established and exercised to

maintain control of these items.

6.0 Covering of Contaminated Surfaces

Radioactivity on equipment should not be covered by paint,

plating, or other covering material unless contamination

levels, as determined by a survey and documented, are

below the "Removable" Criteria of Table 1 of DOE Order

5400.5 (see below). A reasonable effort must be made to

minimize the contamination prior to use of any covering.
