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 Group has deliberated whether actions of an engineering 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 environment 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 range of options and provide data for calculating doses for other options for anyone who wishes to do so.

In NVO-140, and in the previous section of this report, dose estimates - and therefore options - were considered in matrix form (e.g., living pattern vs. diet, or diet source vs. amount of soil removed).
