L? 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. 4. _ ; ¢ 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. 5. “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 ‘background for plans for the recovery of Pu will require: a. ~ b. 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. ~ %. _ Theobjectives of the cleanup are two: on a) "Recovery of the pieces of plutonium that have been : . me TS . _ observed on or near the island surface. “-- (2) - Recovery of plutonium contaminated soil. — SL2
