DRAFT 16 presented within one year after the occurrence. As of this date, no claims have been submitted. The houses built by H&N, an AEC contractor, on Ejit Island in Majuro Atoll, are constructed so that the Rongelapese can remove them to their original homesites. The AEC accepts responsibility for continued medical examinations of the Rongelap people as a routine precautionary measure. The AEC also assumes responsibility for periodic radiological resurveys of Rongelap to determine when the inhabitants may return safely. The AEC will pay for constructing an island communication system between Kili and Jaluit and for family housing units on Jaluit so that Bikinians on Kili may fish at the Jaluit lagoon.'” 8 and 18 Dec 54 CONTRACTOR RADIATION AFL, NRDL, and AEC/DBMscientists collect samples and record radiation levels at Rongelap Atoll." 25-30 Jan 55 CONTRACTOR RADIATION RELOCATION The NRDL and AFL make the most extensive survey and biological collecting trip to date for the AEC at Rongelap Atoll. The work reveals unsafe amounts of radioactivity in shellfish and crabs, important in the peoples’ diets." Feb 55 ADMINISTRATION RADIATION The AEC/DBMestablishes criteria and procedures deemed necessary to protect the health and welfare’of the general populace from consequences of weapon tests at the Nevada test site. The criteria are: up to 30 roentgens, no evacuation indicated; 30-50 roentgens, evacuation only if 15 or more roentgens are saved; and 50 roentgensandhigher, evacuation without regard to the amount of the dose. The procedures are: ‘thake roughestimates of radlatiotidoses béfore and after detonations and then,take’ dose-rate’readings with survey meters, which are held three feet above ground. The NRDLcollects soil and biological samples in the Marshall Islands for a radiological study.’ Mar 55 CONTRACTOR MEDICAL RADIATION Most of the Rongelap natives appear "in excellent general health", according to a medical recheck Dr. Eugene P. Cronkite of BNL, Lt. Cmdr. Samuel D. McPherson of Bethesda Naval Medical Hospital, and Dr. Charles L. Dunham, deputy director of the AEC/DBM.'* A resurvey of flora and fauna of the Marshall Islands by NRDL and AFL reveals ‘significant amounts of radioactive contamination” in the animals, food plants, water, and soil samples one year after their contamination by fallout from Castle les C3 aH C5 Bravo. The U.S. NRDLfinds the highest concentrations of internally deposited activity in marine specimens taken from the northern Rongelap lagoon. Zirconium’*-
