tl et tee te 1. Disposal in water-filled and underwater craters. 2. Land burial where the radiation level of the scrap is not significantly above that on land. 3. Disposal in deep water. Pu excepted, the Task Group has not made recommendations for removal of contaminated soil. For any disposal there should be no pathway to people; periodic followup surveys are necessary. Disposal of Pu in any form is a greater problem, and disposal must protect against exposure for the future. OBSERVATIONS AND CONCLUSIONS The consensus of the Task Group reflects consideration of a range of options and the benefits of reviews and comments. Choice of the method which will optimize reduction of exposures is a matter of judgement. Action such as use of imported foods could he effective but is not recommended, Although engineering actions, e.g., soil removal and replacements may appear to be preferable to restricting use of land for living and agriculture, these actions can otherwise adversely affect the environment and eae ee for some the effectiveness is uncertain. The extent of compliance -by the people with restrictions has been considered, and an acceptable level of cooperation is expected so that they may use land where the radiation environment is or can be made acceptable. Return of people to live on the southern islands, ALVIN through KEITH, is expected to result in radiation doses within the recommended criteria. JANET (Enjebi), which the people desire for a residence island is a special case of the category of islands having radiation and radioactivity levels which preclude living and agriculture. Steps to make this isiand completely or partially available in the near term are important from the social as well as scientific viewpoint. Predicted radiation doses associated with the Task Group recommendation that people live only on the southern islands, ALVIN through KEITH, are given in the following table. The Bikini Atoll estimates and typical natural background levels inthe U.S. are given tor comparison.
