pu DPiepaing, Recovery of plutonium soil concentrations greater than 400 p€f/s 239 2y¥9 oe at Met d. ‘ ? Pu at any depth these levels are found. , The justification is that plutonium at some depth may one day be at the surface. Also, of recovery/contaminated soil sufficient to reduce surface levels to a value well below 40 pCi/g 239,240), thet justification is to keep air concentrations of resuspended plutonium to levels well within national and international standards. After soil removal, all areas should be resurveyed to f\ ensure no pieces or hot spots of plutonium remain. \y’ ae €) finearea observed to have pieces of plutonium and the highest es concentrations is the interior and shoreline of the island | beginning at a line drawn from the ocean reef to lagoon 60 meters wad arrae “ ey if fea Ce Vales \north of the tower (Hardtack Station 1310) to CACTUS Crater. 8.
