4. The possible impact on the Enewetak people and on the environment. Choice of the best overall method for reduction of exposures to the lowest practicable level is a matter of judgment and opinion. The Task Croup has deliberated whether actions of an enpineering nature such as soil removal are preferable to actions that would restrict use of certain islands for permanent habitation and food production. The adverse impact of engineering actions on the atoll enviroment and the uncertainties regarding effectiveness have been viewed on the one hand, and the question of the extent to which the Enewetak people would comply with restrictions on the other. NVO-140 and this Task Group report present the radiation doses that may be associated with a broad ranse of options and provide data for calculating doses for other options for anycue who wishes to do so. The dose reduction expected for one option can be compared with thar of unviher. Lolo: veutis fu: cleanup actions are being prepared by isin; and the impact and acceptability of restrictions can be evaluated through Uiscussions with the Enewetaik Council. In NVO- 140, and in the previous section cf this report, dese estimates - and therefore options - were considered i: matrix form (e.g., living pattern vs. diet, cr diet source vs. amount of soil removed). While these matrices setve to indicate in detail the range of conditions to be found on the atoll, the Task Group feels that its' recommendations are presented more effeetivei: narrative form. There are three basic questions to be addressed: e.¢g., "Is the radiation environment acceptable or can it be made acceptable for the Enewetak people to return to their atoll," "Is the raciation environment on Enjebi acceptable or can it be made acceptabie for the people to return," t and “Are there islands which are not acceptable for people to cenduct their normal agricultural an¢ i
