of the University of Washington’s Laboratory
of Radiation Ecology.
During 1980, members of Brookhaven
National Laboratory researched the protracted
exposure to fallout at Rongelap and Utirik
The thyroid-absorbed dose from these sources
wasnegligible relative to the thyroid dose com-
mitted during the first few days after the acci-
dental exposure.'
The thyroid-absorbed dose tabulated here was
estimated from results on *"I activity excreted
in urine and the specific nuclide composition of
Atolls. The time interval of interest was from
the time each population returned to their home
atoll up to 50 years later. The nuclides consid-
