14. SCOPE: A program of radionuclide &“easurements in soil, water, and biota, radio- ecological transvort modelins, and dose evaluation in the Marshall Islands is propose to fultill two immediate objectives and one long-term goal. Tne immediaie objectives are CO) to meet present high-priority needs for effective renabilitat: of Enewetsk Atoll and (2) to suoport the ongoing evaluation et Bikini Atoll. The long-term goal is to assure a continuing evaluation effort in support of the implementation of resettlement and renabilitation in both regicns. The Enewetak Survey and Eveluation effort that resulted in the report NVO- 140 (Enewetak Radiolcrical Survey) provides a comprehensive description of the _ radiological stetus of that Atoll et one roint in time, for the specific purpase = of evaluating constraints on rehabilitation end Tor developing cleanup plans. The implementation of resettlement, however, requires additicnal studies over a longe time-range to assess the time-dependence of radionuclide removal from the Atoll as well as to support a continuing evaluation effort. wS Q ch tf Ww oe Previous evaluation £ the atolls were besed upon a limited emount of direct sampling of critics) f oo s in the terrestrial food; these foods (ecconut, D Qu ts Enewetak as well.
