greater than 400 pCi/g contamination levels, both in the ejecta and below the pre-detonation surface. Disposal would be by spreading, for levels less than 400 pCi/g, or crater containment for higher levels. 10. The method of analysis of samples was discussed. It was agreed that a gross alpha count was probably the fastest and simplest method to obtain the AAPA ee semen ee yes-no enswer sought. This would not define the isotopic contamination content but would provide a base to be supplemented by radio-chemistry analysis which would provide the isotopic content and should be correlatable to gross alpha count for any specific area. 11. Discussion turned to sampling increment to be utilized. Increments discussed included the averaged 10 centimeter depth used for most of the available data; averaged 20 centimeter depth, based on a nominal 6-inch cut capability for a dozer; and 20 centimeter increments with a specific 5 centimeter sample from each increment. The operations plan specifies 5 cm sample depth because tn eee past experience at Nevada Test Site has indicated that averaging samples of greater depth leads to ancmolous data output. will be the bases for certification of the condition of the islands upon completicn of cleanup, ate Five centimeter depth samples Discussion included the advantages and disadvantages of horizontal averaging versus vertical averaging for sampling. favored vertical averaging. Consensus Discussion also included the capability of the laboratory to analyze the samples produced. Maximum capability would be about 150 samples per day for gamma scan and gross alpha count plus about five percent radiochemical analysis. This level would not permit support of other operations. Other operations could be supported at levels of 50 samples per day input. It was agreed that gamma scan of samples at the laboratory could be used to select samples for analysis. Only the "hot" samples would be analyzed. 5 Other
