2 Page 5, Item i. Is it clear that samples which have a very low gamma level of contamination also have a low plutonium level, particularly in the FIG/QUINCE area? This should be verified. Minutes Page 3, lst full para. It would be helpful to define ''simple yes-no criteria" in a more specific manner. Page 4, Item 8. See above comments on the summary, Item e. Our past experience with cleanup of sites also shows that simply because we . . | “ a are unable to find a record or reason for possible contamination in a specific area doesn't mean that that area is uncontaminated. If there were cable runs or line-of-sight pipes in the central area, then the possibility of contamination should be thoroughly investigated. Page 5, Item 9, last sentence. It scarcely seems prudent to spread contamination once it has been gathered together. Believe that the _ group consensus was that this should not be done. Page 5, Item 11, 3rd sentence. Don't really believe that averaging samples of greater depth leads to anomalous data output. It might lead to misunderstanding of the results because of a lower picocurie per gram value. Suggest this sentence be checked with Bruce Church, Page 7, Item 14, last sentence. While it may have been the Chairman's contention that the effort should not include exploration to locate other possible subterranean pockets, don't believe that this was the _ group consensus. eee Page 12, Item 21. See above comments on Summary, Page 2, Item 2.f. Page 13, Item 22. Not sure that there was agreement that soil brought to Rimit could be used to fill in holes left by cleanup. This could result in recontaminating an area that had just been cleaned. The iterative "one-half distance" technique far delineating the size of pockets of various levels of contamination is mentioned several times (e.g., Summary, Page 4, Item £ and Minutes, Page 3). This - technique is useful for relatively continuous areas or pockets of contamination, but may have limited utility for the heterogeneous contamination situation at Rmit (contaminated material may vary from particle size to many cubic meters). .
