Samples were from a field centered in the island
(portion) arproximately 140 m (from lagoon to ccean)
by 520 m. Aithourh many hivh readings are near the
air-ground interface, concentraiiens at depths up to
140 cm are significant.
Except for four locations,
clustered near the "right-side" of the field, profiles

decrease toe less than 40 pCi/¢ within about the top
35 cm.
Samples will be taken to a depth of 40 cm at
10 em increments and at 20 m intervals (864 samples).
A the hiph-vatue area (140 m X 200 my, samples will
be taken to additional depths of 100 cm (880 additional samples).
Samples were from widely separated locations,
each with adjacent analyses thit did not exceed

40 pCi/g, which sugsests that no extended hot spots
4.0X10
are present.
The one hich reading, from the middle,
northern side of the runway, vill be investigated.
Sazples at 1M cm increments to depths of 100 cm
will be collected from 10 locations in an area approximately 50 m X 80 m encompassing the high value.
