Title: Guidelines for Decontamination of Facilities and

Equipment (July 1982 Revision)

See the memorandum from R. E. Cunningham to G. Page (and

others) dated July 22, 1982. The memo provides NMSS

revision of "Guidelines for Decontamination of Facilities

and Equipment Prior to Release for Unrestricted Use or

Termination of Licenses for Byproduct, Source, or Special

Nuclear Materials."

More than one branch of the Division of Fuel Cycle and

Material Safety have been using a document titled,

"Guidelines for Decontamination of Facilities and Equipment

Prior to Release for Unrestricted Use or Termination of

Licenses for Byproduct, Source, or Special Nuclear

Materials." There are, however, two versions of this

document, dated November 1976 and June 1980, that have

slight differences in wording but not in technical content.

In order to provide a single document that can be used

uniformly by all branches of the Division, the version

dated June 1980 was revised, and this revised version,

dated July 1982, should be used by all branches of the

Division until a subsequent revision is required.

A copy of the July-1982 revision is provided as an

enclosure to the memorandum. The instructions in the

report specify the radionuclides and radiation exposure

rates which should be used in decontamination and survey of

surfaces or premises and equipment prior to abandonment or

release for unrestricted use. The limits in Table 1 of the

report do not apply to premises, equipment, or scrap

containing induced radioactivity for which the radiological

considerations pertinent to their use may be different.

The release of such facilities or items from regulatory

control is considered only on a case-by-case basis.
