DOG {iROIG), EASY (ODRIK), FOX (LOMILIK), AND GEORGE (AOMEN) The northern complex of islands is shown in Figures 16 and 17. Troi ana Odrik are connected by a jong man-mace causeway, while Qdrik is in turn connected to Lomilik by a shorter causeway. Lomilik and Aomen are differentiated only by a narrowing of the land mass. Oniy Lomilik contained any significant amount of radioactive debris and disolayed relatively high levels of external background. sure rate due to soil The maximum expo- contamination measured on each of these islands was: Troij - 40 yR/hr Odrik - 10 yR/Ar Lomilik - 500 yR/hr Aomen - 100 \R/hr The debris from Iroij, Odrik, and Aomen was buried on land. A large amount of non-radioactive scrap was removed from the ocean reef on Aomen and also buried on land. All radioactive metallic debris on Lomilik (maximum 500 uR/hr) was removed and buried at sea. installations, all Fragments of concrete from scientific of which measured Tess than 100 upR/nr, were buried on jand. One low lying, algae encrusted area on Lomilik showed background radiation levels of 500 uR/hr. A soil sample taken at this location contained approximately 55% !02MRh and 45% 59Co as measured by gamma ray spectroscopy. The projected exposure rate reduction for this location is given by Figure 18. Since the absence of !37Cs would indicate that this sample is atypical, a plot is also shown assuming that 20% of the total activity is due to !137Cs and that the !92MRh and 69Co retain their same relative concentrations. This might be more applicable to other locations on Lomilik. Two concrete bunkers on Aomen had areas on the tops and sides which read 5-7,000 uR/hr (6+) at contact. than 200 yR/hr. The gamma exposure rate was Tess Since the potential for exposure to individuals from these sources was negligible, it was decided to leave the bunkers as typhoon shelters. 28 BSCS 0108050
