The majority of the dose rate is attributable to the 1370.
Cesium dominated over the entire post return period and would be of
prime concern for populations returning to a contaminated environment years
after a fission-type initiating event.
Figuce 16 illustrates two possibilities for the Utirik body burden history
during the first three years post return.
The higher body burden resulted from
use of the two measured 6300 body burden means for adults on Utirik and the
observed dietary rate constant from Rongelap.
It was observed on Rongelap that
-031% of Gon was removed from the diet pathway each day in addition to
