exposures are referenced to the time of the DOE Northern Marshalls survey in
1978.
Snose estimates derived from whole body counting (in-vivo) by Brookhaven National
Laboratory (BNL). these estimates are much more reliable than estimates from dose
models. .

fhe average adult dose in 1982 represents a 56 percent increase compared to 19861
due to relaxed restrictions.
The high individual dose of 6.14 Rem/yr was
expected to be reduced to less than 0.1 Rem/yr if restrictions had remained
effective.
bose prediction developed by Lawrence Livermore National Laboratory using results
from Northern Marshalls survey and dose models.
This exposure estimate was given
to the Rongelap people in 1982 in a Marshallese English booklet.
This value ia
not supported by in-vivo monitoring data, and has never been corrected.
