Washing by breaking seas would reduce the rediation levels to « point where little or no shipyard decontamination would be necessary. LCUs were required only for roll-up of Bikini and Rongerik, ‘the Thay were decontaminated to an average reading of about 30 ar/hr, pernit~ ting their cross to operate then for chort periods of time without acquiring too great dosages. live aboard. the crews did act agein move back and By YANRES plus ten daye the LCUs were reading en average of lO mr/hr. Decay during the period Croa their relesse from CASTLE | te thelr resumption of operations elseahere was expected to reduce their contamination sufficiently to preclude shipyard decontenination, One was loaded aboard BELLE GROVE for shipment to Pearl Harbor, three were left at Eniwetok to enait 11f6 to the western Pacific, — . 36. Tne biggest deconteminstion problem presented to the task group was that of the YsGs, for experimental purposes they were purposely exposed to heavy fallout on three shots, ROMEO, UNION ant YANXES, YAQ 39 was equipped with washdom gear, TAQ 40 was not. By keeping the two anips in close company and operating the YAG 39 weshdown gear, comparison of contamination levels on the two ships served te show the wuchiow: goor's effectivenesa. Deconteninetion after each shot wes necessary to permit manned operation of the craft up to shot tins minus a few hours on the subsequent shot, mi to get « true picture of new contaminntion received. Initially both ships wore operated as drones manecurered frou an airborne control station 5\
