of 239pu in [newetak soil, the Task Group recormends the following: l.- Any areas or locations where soil concentrations of 239py are greater than 400 pCi/ez should receive corrective action with contaminated soll removed for disposal. Situations with soil levels in the 40 to 400 pCi/g range may receive corrective action with each area or location evaluated on a case by case basis. following guidance is provided for this evaluation: ae Islands with soil levels in the above range may be divided into two categories, those of sufficient size for construction of permanent houses, and those that are not. Renoval of 239pu contaminated soil is better justified within the range above for the larger islands such as JV™T or SALLY where permanent nousing may soneday be located and for near surface locations on the larger islands. Cc. The snaller islands may be considered of less concern, Their longtern outlook is uncertain since they are sometines increasing in size and sometimes erroding away. Smill islands may be washed over by storn waves and are not a safe site for permanent housing. From that viewpoint, they are in the same category as unnamed sandbars along the reef where other islands may have disappeared or be forming. The amount of effort that properly may be given to soil renoval in this ranze increases as the soil concentration increases. Once a soil removal action is to be taken, the objective is to achieve a substantial reduction in plutonium soil concentrations, and further, to reduce concentrations to the lowest practicable level, not to reduce them to some prescribed numericel value. yee ce 42-42
