DR. ANSPAUGH: Okay. If I may have the first viewgraph, David. (LRA-41). From our original discussions, I think at the very first meeting of this_Committee and even its predecessor committee, we wrestled with the problem of what do we do about areas that are really beyond the original estimates of exposure, external exposure, and how do we deal with it and how far “do we go. I think we always agreed that additional measurements wou Id be usefuT>. This is actually an old viewgraph, from many meetings ago, and we generally concluded that it, would be useful to have con10 temporary measurements of the deposition of radionuclides in a broader geoll graphical area and: F-don't think that we have ever come to a reasonable way 12 of saying where we will,draw that line, but, nevertheless, 13 everybody felt that the”original I think that fallout patterns were not extended far 14 enough to answer all of the questions that we had. 15 Some of the methods that we-proposed were aircraft measurements, field 16 spectrometry and soil sampling. 17 all of these methods. 18 of the NURE aircraft data and the Phase II that we initiated following the 19 May meeting has extensively used the techniques of field spectrometry to 20 measure the cesium flux and also soil sampling so that's just to emphasize, 21 again, 22 where we can calculate doses. 23 Harold Beck discussed the analysis that he is doing that this whole process The next As_ it.turns out, we are actually pursuing viewgraph is being undertaken to extend the region ~ (LRA-42) indicates . the— dose determination 24 methodology that's based upon these techniques and—this,I would like to 25 emphasize, 26 demonstration of this technique throughout Utah, but, basically, the key to 27 this whole business 28 at a site at some estimated time of arrival. is based upon the work that EML has done primarily, and their is to calculate the amount of cesium-137 that arrived 189 Now, if we can in fact cal-
