til the license is termi nated, after which they may be stored with other plant records: (1) Environmental surveys;- ' (2) Facility radiation surveyS; (3) Inspections of the physical barriers, and (4) Abnormal occurrences. 4. DECONTAMINATION FOR RELEASE FOR UN RESTRICTED USE If it is desired to terminate a license and to eliminate any further surveillance requirements, the facility should be sufficiently decontaminated to prevent risk to -the public health and safety. After the decontamination is satisfactorily accomplished and the site inspected by the Commission, the Commission may authorize the license to be terminated and the facility abandoned or released for unrestricted use. The licensee should per form the decontamination usiOg the following guide lines: '•' a. The licensee should make a reasonable effort to eliminate residual contamination. b. No covering should be applied to radioactive surfaces of equipment or structures by paint, plating, or other covering material until it is known that contamina tion levels (determined by a survey and documented) are below the limits specified in 'Table I. In addition, a reasonable effort should be made (and documented) to further minimize contamination prior to any such covering. c. The radioactivity of the interior surfaces of pipes, drain lines, or ductwork should be determined by making measurements at all traps and other appropriate access points, provided contamination at these locations is likely to be representative d co6ntamination on the interior of the pipes, drain lines, or ductwork. Surfaces of premises, equipment, or scrip" which are likely to be contaminated but are of such size, construction, or location as to make the surface inaccessible for purposes of measurement should be assumed to be contaminated in excess of the permissable radiation limits. d. Upon request, the Commission may authorize a licensee to relinquish possession or control of premises, equipment, or scrap having surfaces contaminated
