CONCLUSION The principle results of this investigation were that: 1376, and 6570 were major contributors to the committed effective dose equivalent; the overall body burden pattern was one of initial increase followed by continuous decline over a period of years; the daily intake pattern was probably one of continuous decline, this conclusion was based on the fitting of sequential body-burden data to Eq. 2; the impact of each muclide on internal committed effective dose equivalent was dependent upon the time between contamination and rehabitation; and the internal committed effective dose equivalent exceeded external dose equivalent during the rehabitation period. The sparse 23954 data indicated further re- search was necessary in order to estimate accurately the activity intake and committed effective dose equivalent from this nuclide. For committed effective dose equivalent, the impact of nuclides with a short mean residence time in the diet (Pen, 6069) was greater at Utirik because the population reinhabited within months of the BRAVO event. . . : . ‘ . 1] 37, clides with a long mean residence time in the diet ( S; 90 greater at Rongelap because of greater initial contamination. 23 The impact of nu-~ Sr, 55 Fe) was
