As to the question of whether equivalent dose reductions (equivalent to reductions obtained through modification of the diet) could be obtained through removal of contaminated soil, the Task Group holds the opinion that some reduction is possible. However, the magnitude of this reduction is uncertain and can only be determined reliably through measurement of the radionuclide content of the important food items such as pandanus and breadfruit grown in the modified condition. This would require a research effort to grow test plantings of the various food crops in the soil renoval and replacement areas using various fertilizers and trace minerals, and analysis of radionuclide content of the fruit produced. There is the possibility th: radioactivity in the fruit could be reliably predicted from analysis of stems and leaves of young and as yet unproductive plants. additional study. This would requi- Considering the tine required for such studies and that the levels of radioactivity in soil are being reduced by radioactive decay and weathering, it may take about as long to return people to JANNT using soil removal and confirmatory studies as would be needed without suci. actions. In the commercial agriculture areas of JANLIT and the other northem islands the item of concern is the radioactivity level of coconuts (i.e., “Can the Enewetakese sell their copra?"). Data in NVO-140 (pr 560-562) indicate that 137¢6 is the principal man-made radionuclide found in coconu meat, with the relationship 1370, (copra) = 1.3 1376, (soil) at 1376, soil concentrations greater than 4.7 pCi/gm.
