d. Recovery of plutonium soil concentrations greater than 400 pel /27>?? Pu at any depth these levels are found. The justification is that plutonium at some depth may one day be at the surface. of Also, recovery/contaminated soil sufficient to reduce surface levels to a value well below 40 pCi/g 239,2405 The' justification is to keep air concentrations of resuspended plutoniun to levels well within national and international Standards. After soil removal, all areas should be resurveyed to ensure no pieces or hot spots of pliutonium remain. e. The area observed to have pieces of plutonium and the highest soil concentrations is the interior and shoreline of the island bepinning at a line drawn from the ocean reef te lascen 60 meters marth ™ - nf on the.

Test plantings of pandanus, breadfruit, coconut, and arrewroot should be made, as soon as growth can be assured, on each of the islands on which these plants are to be grown. As edible parts of these plants become available, their concentration of 90g y 13765, 23952405, and any other significant radionuclides should be measured and compared wit. the Radiological Survey predictions. These studies will provide for a determination. to be made of the earliest time at which planting of food and commercial crops can be nade.
