Five locations were sampled on Edna as part of the Fission Product Data Base Program in support of the dose assessment (see Section 6.11). Soil from three of the locations was analyzed for 90sr, Tables 7-1, 7-2 and 7-3 summarize the results for 0-15 em data for 137g, 90s; and 239,240 py, respectively. The island average transuranics value reported in the Certification is 33 pCi/gm for surface soil, and the transuranics classification is Residence. 7.3.6 Edna's Daughter Edna's Daughter, a tiny islet about 0.5 hectares (ha) in area with a few bits of vegetation, is located on the reef just north of the Mike event crater. The island has no Marshallese name, and was not mentioned as existing during nuclear testing activities. Its location suggests that it may have grown up around throwout from the Mike event. The islet is visible in 1972 aerial photographs, but was not sampled in the 1972 survey. No data are available on the amount, if any, of exposure to Edna's Daughter due to fallout from nearby nuclear events. There were no scientific stations, no debris, no ground zero sites, and no burial areas on Edna's Daughter. Because of its small size, no IMP measurements were made on the island, nor were any accurate maps drawn. However, soil samples were taken at two locations, with two composites at each of three depths for a total of 12 samples. The approximate locations and the results of the soil sampling are shown in Figure 7-24 and are summarized in Table 7-4. The highest TRU activity in any soil sample was 122 pCi/g, so Edna's Daughter met Condition D without any cleanup. This island was not sampled in the Fission Product Data Base program. The island average transuranics value reported in the Certification is 103 pCi/gm for surface soil, and the transuranics classification is Food Gathering.
