Instructor's Notes

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, Ch. 2

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

contamination prior to use of any covering.
