UiESeR TIO, C6pe Spee DOBARCHIVES? egdel? The island complex and separate islands along the northern and alang the southern rim of the Atoll should be cleared of contaminated scran metal, These would include the Aomen-Odrik complex, Iroij, Nam, Enidrik, and the Aerokoj-Enenan complex. The level of effort desired is the complete removal of all scrap metal’ on or near the surface of these islands, The final disposition of this material should be such that it is unavailable to the ceturning population, Undamaged or lightly damaged concrete bunkers should be left in place throughout the Atoll. These are judged to provide a benefit to the returning population as shelter against storms and temporary residence for short periods at locations where no other buildings exist. The observed levels of radiation in reinforcements of bunkers can be expected to be reduced at the same rate or possibly faster than levels in adjacent soil. The bunker with iron aggregate on Aomen should be repaired such that no further flaking of the iron can occur. The steel doors should be removed from all bunkers to prevent accidental entrapment, Rusting climbing rungs, stairways, and any protruding steel on the outside or inside of bunkers should be cut off with disposal along with contaminated debris, with the exception of the large diagonal structural members on the large bunker on Aerokoj which should be left in place. The damaged bunker at the end of the sand island west of Nam should be removed because of the physical hazard it presents and because of its lack of any useful purpose. For the sand island bunker, the radiation level in the twisted steel members is also a consideration. The steel members protruding from concrete footings or forms on the islands listed in 2. above should be removed for disposal. These . have no utility for native use and many of the metal members show elevated levels of gamma radiation. parts should be removed. Both the steel and concrete A followup survey should be made within 12 months after return of the population and at appropriate intervals thereafter to ensure that no contaminated scrap has found its way into the village or work area oy ae ot 4 fw on Bikini or Eneu. ¥ 3. 4 i
