s may then be about 480 tons per year. If the copra produced through the agricultural rehabilitation program contains as much 137. as in the 1967 and 1969 samples, i:e., 124 to 120 pCi/em, and considering that in producing copra, coconut meat is reduced in weight by the sun drying process by as much as 50%, the copra may contain up to 2b0 pCi/gm. The fertilizing of the new plants which is being done in | the agricultural rehabilitation program may reduce the 137 Cs levels in the copra. The relationship between 137¢5 in coconut meat and in soil wnere coconut trees are growing is not known. Available soil samples have come from one place and coconuts from another on Bikini. It would be desirable to have samples of coconut and soil from the same place and to fertilize an existing tree to see what change in radioactivity content in the coconut there may be compared to unfertilized trees. Also, it would be desirable to have samples from trees wherein 2 inches of top soil were removed as suggested by the Ad Hoc Committee for Pandanus and from trees where both fertilizer and top soil removal were used. It would be desirable to sample coconut meat and coconut frond. for 13705 from existing trees on Bikini. If levels tn frond and meat are related in some way, then predictions of coconut meat So FABB0oe- pot‘ 137os could 33%
