Z. 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. The 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. b. Removal of 239 Dy contaminated soil is better justified within the range above for the larger islands such as JANET or SALLY where permanent housing may someday be located and for near surface locations on the larger islands. The smaller islands may be considered of less concern, Their long-term outlook is uncertain since they are sometimes increasing in size and sometimes erroding away. Small islands may be washed over by storm 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 re- moval in this range increases as the soil concentration increases. e. Once an action is 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 numerical value. 3. E. Areas or locations showing less than 40 pCi/g do not require corrective action because of the presence of plutonium alone. Recommended Guides The standards issued by FRC are recommend as the basic guidance for evaluation of exposures to individuals to Enewetak. “JH-9
