For the average Rongelap adult, the residence interval begins Juic 1,
1957; however, many adults were reported to have resettled during the ne.! 3 to
6 months (Co80b).
The composite dose equivalent rate indicated that a bicd
maximum of approximately several hundred millirem per year persisted for several hundred days.
