plantings of coconut would be needed in areas where removal of soil has been conducted and the level of 137 Cs in coconut meat analyzed before any commitment is made for planting of coconut trees in commercial quantities. As previously noted, it may be possible to predict the level of 13705 in coconut meat through analysis of stems and leaves of immature trees. This would save time.: The Task Group points out that measurable quantities of tests related radioactivity will be found in copra from all islands in the atoll, the highest jJevels from the nothern islands. No quarantee can be given for a level of 1376, acceptable in the market place, however, the level of natural 40, appears to be a reasonable guidepost since there has been no requirement to reduce the level of naturally occuring radioactivity in copra. DISPOSAL OF CONTAMINATED MATERIAL For disposal of contaminated material, there appear to be several categories, each requiring separate consideration: 1. Contaminated scrap, non-plutonium. 2. Contaminated soil, non-plutoniun. 3. Contaminated scrap, plutonium. 4. Contaminated soil, plutonium. 5. Pieces of plutonium metal. Some of the above are below the ground surface such as in burial sites. Some is near the surface such as the pieces of plutonium metal on YVONNE. With regard to disposal, the Task Group considers it appropriate to cite the objectives for disposal, to list possible approaches for disposal, and to suggest possible interim measures where appropriate. -14-
