calculations and we can also compare that number with the number that came from the rainfall method. And the next viewgraph (LRA-47) shows the steps in this measurement strategy of what we now call Phase II. We select the desired communities. Those were selected on the basis of geographical coverage where we had a feeling that the fallout might have gone. Areas were selected essentially to provide a circle around the areas that we have been measuring so that we did select about 100 communities where we felt it was desirable to look for a soil sampling site. 10 date sites. 11 assisted Frosty's group then went out, selected these They were followed by the Livermore people, in this operation, candi- and EG&G also to measure cesium-137 by field spectrometry. 12 That's mainly a confirmatory technique to make sure that that sample does 13 have a representative amount of cesium in there because if it has been 14 seriously disturbed then we essentially get very little values of cesium, 15 and we would not take soil samples at that site. On the basis of that, we 16 then select sites for soil collection, collect the soil samples, we select 17 sites for following analysis by laboratory methods. 18 Step 6. We have just finished Last May we essentially had just done this part (Step 1), and so 19 we've been very busy since the May meeting doing all of this measurement by 20 field spectrometry and collection of soil samples. We now have picked 21 these sites (for Step 6), and I'll get to them in a moment, which ones they 22 are, and then we'll follow that with our cesium measurements. 23 samples we'll 24 back then and calibrate our field spectrometry measurements, 25 know the distribution with depth to get a semi-independent measurement of 26 the 27 (Step 7), if the distribution with depth continues to look reasonable and 28 provides us with confidence that that site has not been further disturbed, total look at the distribution (of cesium) with depth. cesium deposition. Now 192 on the basis of this In the soil We can go and once we measurement
