Sample collections Water samples were collectcd from the water supplics of all inhabitce areas. About two quarts of water were transferred to a polycthlenc bottle at each site, Thesc will be turned over to the New York Operations Office, AEC fanalysis, . é Soil samples were collcctecd at all inhabited arcas and also at scvcra!t uninhabited islands, In collccting tho soil samplcs a one foot by one foot square was markedon the ground and soil to about one inch of depth was removed from the square and transferred to a cardboard containcr, The primary samplcs will be turned over to the New York Operation Office, 435C, for analysis, and some smaller samples will be analyzed by Program 2 of TU 13, Listed in Table 3 are the samples taken with the dosc rato measured .. at waist height at the location where they were taken. mm ok Am une cw 2237 AVAILASLE COPY wl Le py Sample No. TABLE 3 ~ SOIL Atoll Island Date Ur/ir yt 2 3 Rongelap Rongelap Rongelap 8 Mar 6& Mar 440 280 4 Rongelap 8 Mar 340 5* - && Te RongefLap Rongelap Rongelap Rongelap (North end) Rongelap (Center of village) Rongelap (1 mile north of village) Rongelap (near South cistern of village) ge 9 10 * Utirik Bikar Rongerik Ailinginae Eriirippu Eniaetok Kabelle tirik Bikar Fniwetak Sifo 8 Mar 220 8 Mar 8 Mar 8 Mar 2200 900 2000 SY BRENO FRC 9 Mar 140 SAV BRUXO Frc 9 Mar 40 10 Mar 10 Mar 280 100 %Small additional sample taken for analysis by Program 2 of TU 13, <ul \ Hd
