<br />.annex C <br />To LC 12.3.7.1 <br />The instructions in this guide in conjunction with Table I specify the <br />radioactivity and radiation exposure rate limits which should be used in <br />accomplishing the decontamination and survey of surfaces or premises and <br />equipment prior to abandonment or release for unrestricted use. The limits in <br />Table I do not apply to premises, equipment, or scrap containing induced <br />radioactivity for which the radiological considerations pertinent to their use <br />may be different. The release of such facilities or items from regulatory <br />control will be considered on a case-by-case basis. <br />1. The licensee shall make a reasonable effort to eliminate residual <br />contamination. <br />2. Radioactivity on equipment or surfaces shall not be covered by paint, <br />plating, or other covering material unless contamination levels, as <br />determined by a survey and documented, are below the limits specified in <br />Table I prior to applying the covering. A reasonable effort must be made <br />to minimize the contamination prior to use of any covering. <br />3. The radioactivity on the interior surfaces of pipes, drain lines, or <br />ductwork shall be determined by making measurements at all traps, and <br />other appropriate access points, provided that contamination at these <br />locations is likely to be representative of contamination on the interior <br />of the pipes, drain lines, or ductwork. Surfaces of premises, equipment, <br />or scrap which are likely to be contaminated but are of such size, <br />constuction, or location as to make toe surface inaccessible for purposes <br />of measurement shall be presumed Co be contaminated in excess of the <br />limits. <br />4. Upon request, the Department may authorize a licensee to relinquish <br />possession or control of premises, equipment, or scrap having surfaces <br />contaminated with materials in excess of the limits specified. This may <br />include, but would not be limited to, special circumstances such. as razing <br />of buildings, transfer of premises to another organization contanuing work <br />with radioactive materials, or conversion of facilities to a long-term - <br />storage or standby status. Such requests must: <br />a. Provide detailed, specific information describing the premises, <br />equipment or scrap, radioactive contaminants, and the nature:, extent, <br />and degree of residual surface contamination. <br />-28- <br />
