Table 7. Population-weighted average total dose (external plus internal, mGy) to adults of four groups of atolls and/or
communities (see Fig. 2). Grouping is based on similar levels of deposition of total '*’Cs (see Fig. 2). Input data derived
from Tables 2 and 5. Range in parentheses represents the minimum and maximum total dose within the groupofatolls
or communities. All values rounded to two significant digits.

from the mid-latitude atolls. Adults among the Rongelap
Island/Ailinginae/Rongerik evacuees received the largest cumulative doses, six to eight times as great as adults from Utrik.
Recognizing that the doses within each of the four
areas in Fig. 2 can be represented by the doses to Majuro
residents, Kwajalein residents, the Utrik community, and
the Rongelap Island community, Table 8 provides cumu-
lative radiation doses (external plus internal) at those
atolls for all birth years from 1930 to 1958. Those born
in or before 1930 would be of adult age at the time of the
Table 8. Total radiation absorbed doses (mGy) to four tissues and organs of representative persons by birth year (<1931
through 1958): sum of external and internal irradiation; all values rounded to two significant digits. Doses for Utrik and
Rongelap Island communities account for relocations.
