Samples were from a field centered in the island

by 520 m.
Although many high readings are near the
air-ground interface, concentrations at depths up to

140 cm ara significant. Except for four locations,
clustered near the "right-side" of the field, profiles
decrease to less-than 40 pCi/g within about the top
35 cm.
Samples will be taken to a depth of 40 cm at
10 cm increwents and at 20 m intervals (864 samples).
A the hiph-vatue area (140 m X 200 m), samples will
be taken to additional depths of 100 cm (680 additional samples).

Samples at 10 em increments to depths of 160 cm
