Case 3 also provides for the removal of cantannnated serap to negate the possibuity of any radioactive laters reaching the world’s markets. Although Case 315 composed of all actions deseribed in Case 2, it also proawdes for further actions in establishing nnd cuauntaining raciolomieal safecuards, suel ay the quarantine of Runtt. In agditien to Uns quarantine, (Parayraph 3.5.4.0), Case § recomnends thal studies be conducted as follows: « \ test planting proeran: on Lijebr to determine ahen exposure would be ageeptatle criteria v ithout the reuioyval of sok This provram tas been initiated. witht Case 3 permits partial use of areas af the atoll having low radioactive Jevels, greatly recuces radioactive hazards for the indefimte future, and perouts living patterns which, with high ‘confidence, are expected to result in population uoses well below the ERLWA guidelines, This case does restrict habitation to the southern islands, Jinedroi through hidrenen, and does nat recommend speeifie action against radioactivity in the soils of Hokohia, Bokombako, and hirunu (Figure 9-3). 3.5.3.1 Hubitation Residence would be restricted to southern islands, dinedrol through Kidrenen.
