The CINCP:CFL? advisory included no healtir* hasard Probles for surface and aiv routes, but that fall-out on Ailcin’ itoll, ae well am damage to structures, would delay re-entry several days. Furthor, the advisory stated that NYKOFO Flicht .ble wa schednled for 2 March and that it was not anticipated further acticn would be necessary. During the trip beck to BYINSTOK on the nicht of B Day, the flees encountered a wide area of finely divided (appsrently lose than 5 micron) particles wrich caused top=~side intensities as high ae 390 ar/hr. Appro= priate measurures were instituted by the Navy Taek Group Ccmander to the effect. that all personnel not essential to open deck duties would rensin indoors. Ships’ wather doors were closed ani the wshdom systems operated intermittently. 11 personnel were debarked at EMIWETOE by abcut 1000M, 2 Mareh. The TG 7.4 radsafe monitor order to ROMGERIE wie KNAJALEIM, arrived over 20NGEZiIK at about O945M, 2 March. A pase was made over the length of the island where readincs from & .N/FIR TLB instruments were 200 ar/hr at 500 feeb and 350 mr/hr at 250 feet. The latter reading and-a request for additional aircraft ws relayed back to TG 7,4 via KWiJsLEIN. The relay resulted in considerable delay and sisunterstandings due to zarbles. Upon landing at RONGERIX at 1130M, tho monitor advised the detachment, to evacuate. The following additional radsafe readings were takens &e Inside a building where the men spent most of their tiner: 4600 nrf/hr.° (Reading was. low because the building hed been washed dow early in tho mortting, a Outside the above building, waist height: 1800 mr/hr to 2,00 .

Ei-ht men were loaded cn the aircraft end evacuated to KWiJ.LEIN arriving at about 100M, 2 March, Due to non-availability of additional amphibious airlift, tho remaining 20 personnel were picked up on a return trip, and discharged at KW.J.LEIN shortly after 1900H, 2 March. .J1 personnel wore deconteminated by the TG 7.3 search squadron stationed on KW..J. ° & approximately 1200M, 2 March, iadsefe of the task force was advised of the TG 7.4 monitors intcntions to evecuate NONGEUK. In the absence of intensity readings it was mitually azreed not to suthorise evacuaticn and to request radiation intcnsity rcoadinss. This resulted in the pussling information of "3,2 r/hr at one inch® and the more useful reading of 340 mr/hr at 250 fect. It was mitually acreed (by the TO 7.4 and Task Force Radsefe Officers) that an ovacuation was necossary and verbal authority was civon to do so..
