ingestion rates for di.ffcrcnt subgroups of the Bikini Island
population based on the individual measurement data from which Tables
1, 2, and 4 were derived.
Secondly, the~e mean activity ingestion

rates and individual residence interal values we used as input data
to mathematical models applied to inhabitants who did not participate
in our personnel monitoring programs.
The models describe various re-
gimes for the uptake, retention and excretion of internally deposited
radionuclides.
Finallyj dosimetric models which allow for constant
continuous uptake of
90
Sr
and stepwise increasing uptake for
137c~
were chosen to determine the internal dose equivalent and dose equivalent commitment for all inhabitants.
