Rather than establish firm, restrictive criteria for the removal of radioactive artifacts, or the elimination of high background areas from the islands of the atoll, each situation was viewed in terms of the potential oo exposure versus benefit. All debris or artifacts having little or no useful i value were removed. e All scrap metal or concrete with contact readings greater ecalger than 100 micro-R pér hour (uR/hr) was treated as radioactive waste and buried at sea. cases, Three specific locations were selected for this burial. scrap reading less than 100 uR/hr'was buried on land together with non-radicactive debris. This was only done on islands where areas exhibiting background levels in excess of 100 uR/hr were found. aa In some No radioactive debris at any level of activity was buried on the islands of Bikini, Eneu, or Aerokoj}. The exterior of several bunkers, located on the northern complex (Iroij, Odrik, Lomilik, and Aomen) and Nam, exhibited levels of radiation up to 7x102uR per hour (uR/hr) (B+Yy) at contact. uUR/Hr maximum. The net gamma levels were 200 The levels inside the bunkers were less than 10 uR/hr. 1 Since the potential for personnel exposure was negligible, and the bunkers were desired as typhoon shelters and storage buildings by the natives, tie
