radionuclide ingestion is no longer a problem. To develop the
-facts,-test plantings with and without soil removal may be made.

Construction and agriculture would be deferred until produce

from test plantings showed acceptably low levels of radioactivity.
Testplantings without soil removal would have least adverse
impact on the island environment.

Concurrent with the Enjebi work, radioactivity levels should be
“measured in coconut and other food crops grown on PEARL,

CLARA, ALICE, and BELLE.- Produce from YVONNE should
be included after removal of plutonium contamination.

“All radioactive scrap metal and contaminated- debris now or

later identified should be removed. This includes three

locations on SALLY and one on ELMER where buried _
‘contaminated debris should beexhumed and removed. _

YVONNE, ‘quarantined by the USAF in 1972, should remain

quarantined until plutonium contamination on that island has
beencleaned up. An authority responsible for enforcement

of the quarantineshould be identified and in residence inthe
atoll if people return to.the atoll before cleanup is completed. '
Only general recommendations for cleanupof Pu on YVONNE
can be presented at this time. An accurate picture of this
contamination should develop as the decontamination proceeds.

The area observed to have small pieces of plutonium and the
highest soil concentrations is about 30% of the island. A

Assembly of a team of experts to interpret field radiation
and radioactivity measurements, advise on cleanup actions
and provide necessary health physics support. A Public
Health Service group, now part of EPA, provided radiological assistance for cleanup of Bikini Atoll. Similar
support should be sought from EPA for Enewetak.
‘Decontamination of YVONNEis seen as an iterative
process. This amounts toa search for and removal of

the higher plutonium levels in soil.
