GREER TITRE SER ORES § REPORTERTETRA SOTEENTE TEPER SESREO Fission products and induced radioactivity found on such scrap and debris, particularly scrap metal, should be made unavailable to the returning people. Possible approaches are: 1. Disposal in water-filled and underwater craters. t . 2. Land burial where the radiation level of the scrap is no 3. Disposal in deep water. significantly above that on land. 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 cf 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 be 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 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 island 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 Groups recommendation are given in the following table. The Bikini Atoll estimates and natural background estimates of typical levels in the U.S. are given for comparison.
