118 Health Physics August 2010, Volume 99, Number 2 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.

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.
