was 4.5 rem{A-57). Because the Utirik peopie
moved back earlier, their cumulative dose was
apdout 16 rem, despite the fact that tneir initial
exposure was less. However, since noth groups
were eating quantities of subsidizea foods
brought in during the early years. and because
most of the people were awaypart of the time,
these estimates were probably hign.
The cumulative radiation doses received by
the Marshallese are not very different from
those received by the average U.S. citizen
‘about 5 rem in 25 vears) or by inhabitants of
Denver, Colorado about 7 rem in 25 years).
When the Rongelap people left their island
again in 1985, the exposure rate was jess than
that of the people in the United States. This was
partly due to lower levels of the natural background in the Marshall Islands.
