Any areas or locations were soil concentrations of 232>5 are greater
than 400 pCi/- should receive corrective action with contaminated
soil removed for disposal.
Situations with soil levels in the 40 to 400 pCi/g range may receive
cocrective altioa vith #acu 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

Removal of 739Py contaminated soil is Detter justified within tue

The smaller islands may be considered of less concern.
