begun or before completion, an authority responsible for enforcement of the quarantine should be identified and should be in residence in the acoli when people return. The distribution of plutonium contamination on YVONNE is sufficiently 7. complex that specific recommendations for cleanup cannot be presented. It is expected that the true picture of this contamination will unfold as the decontamination effort proceeds .4 Presented are some of the ——— ——gequirementsand objectives that will establish a background from which plans can be made for recovery of plutonium on YVONNE. ao b yr Decontamination of YVONNE is seen as an iterative process, namely, removal of soil, monitoring of radioactivity levels, and removal of more soil.
