VARIATIONSIN FIELDEXPERIENCE AT ENEWETAK PRE- AND POST-CLEANUP DATA ARE NOT ABSOLUTELY COMPARABLE FOR VARIOUS REASONS, BUT REPRESENT THE BEST ESTIMATES AVAILABLE DURING CLEANUP. ee IRENE CLEANUP WAS DIRECTED TOWARD REMOVAL OF SUBSURFACE POCKETS OF TRU ABOVE CRITERIA, RATHER THAN REMOVALTO MEET SURFACE CRITERIA. THERE ARE NO COMPARABLEPRE- POST TRU DATA. JANET CLEANUP WAS CONDUCTED IN 1/4 ha BLOCKS IN "WORSTFIRST" ORDER WHERE EVER THE BLOCKS OCCURED. PEARL CLEANUP WASDONE AS (ESSENTIALLY) ONE LARGE BLOCK WITH 2 SMALL AREAS REQUIRING A SECOND "LIFT". SALLY CLEANUP CONSISTED OF 3 SMALL AREAS WHERE AS MANY AS 5 ITERATIONS OR "LIFTS" WERE REQUIRED; ESSENTIALLY A COMBINATION OF SURFACE AND SUBSURFACEEXCISION. YVONNE CLEANUP WAS QUITE COMPLEX AND NO COMPARABLE DATA EXIST FOR VALID PRE- AND POST-CLEANUP COMPARISON.
