COASTLINE AND DATA COLLECTION LOCATIONS FOR ISLAND MARY The island average transuranics value reported in the Certification is 19 pCi/gm for surface soil, and the transuranics classification is Residence. 7.4.5 Mary Ig Daughter Mary's Daughter is a small islet about 0.5 hectare in area located between Mary and Nancy. The island has no known Marshallese name and was not sampled during the 1972 survey. There is very little vegetation on this island. No data are available on the amount of exposure this island received as a result of nearby nuclear events. No debris, no ground zero sites and no burial areas were known or suspected on Mary's Daughter. Because of its small size, no IMP measurements were taken on the island but soil samples were collected at four locations with two composites at each location for a total of 8 samples (see Section 4.2.1 for details on the soil sampling procedure). The locations and the TRU results of this sampling are shown in Figure 7-32, and a summary of the results is given in Table 7-4. The maximum TRU activity in any soil sample was 138.8 pCi/g (see Tech Note 2.22). 239
