may be seen that the earlier upper bound estimate for the people returning to the souther islands of 0.05 added cancers above the 41 cases expected from other causes (page 30) is increased only to 0.09 added cases. Similarly, the upper bound estimate for the people returning to Enjebi of 0.66 case added to the normally expected 27 cases is changed to 0.99 case. We emphasize, however, that these are upper bound estimates, that the actual risk is probably smaller, and may actually be zero. Conclusion. _We have reexamined our earlier Enewetak health effects estimates in the light of more recent dose and cancer risk coefficient estimates, still small. find the risks We note that our revised estimates remain in remarkably good agreement with those provided by the DOE. We still conclude that it is entirely possible that the radiation exposures of the Enewetak people resulting from return of the dri-Enewetak to the southern islands and the dri-Enjebi to their home "will never result in even a single case of disease among either the returning population of their descendents."
