Purposes of this project were to (1) injury to the human beings exposed, evaluate the severity of radiatidn (2) provide for all necessary medical care, and (3) conduct a scientific study of radiation injuries to hum beings. The organizations and ships involved were: Naval Medical Research Institute Naval Radiological Defense Laboratory (NRDL) Patrol Squadron 29 (VP-29) Naval Air Station, Kwajalein Los Alamos Scientific Laboratory (LASL) USS Nicholas USS Renshaw USS Philip Applied Fisheries Laboratory, University of Washington Hanford Atomic Power Operations OPERATIONS. The primary operation was the evacuation and decontam[- nation of the people involved from 28.5 to 78’hours after BRAVO was defonated. This process and the operational units involved are described Chapter 4. In The evacuees were taken to Kwajalein where immediate medic}. needs were attended to and initial scientific studies made. Residual fa- diation at the contaminated atolls was surveyed during March to establjsh the exposure levels of the natives. ble 66. These missions are summarized in Pa- The people of Rongelap were later taken to Majuro in the Marsfalls where they remained until 1957, when they returned to Rongelap. Utiri which was less heavily contaminated, was reoccupied by its evacuated ighabitants in June of 1954. Medical followup studies on the Marshall Iq- landers have continued from 1956 to the present, under the supervision the Brookhaven National Laboratory (Reference 64). The U.S. service pdr- sonnel were taken to Tripler General Hospital in Honolulu for bioassay observation, but they have not been included in the medical reviews by Brookhaven. 188
