Thus, for example, samples which
were 10-cm thick will be considered equally with samples which were 15-
em thick if they both were reported to have the same plutonium concentrations.
Accordingly, islands or portions of islands which the Survey
showed to have plutonium at less than 40 pCi/g will not be investigated.

Enclosure 1 differentiates those islands and portions of
islands which might require soil removal from those which will definitely not require soil removal.

Each Pu suspect area will be surveyed to establish the
