’ ABSTRACT
An estimate is made of the radiation dose to the thyroids of Rongelap
children following the Bravo event of March 1, 1954.
The available experi-
“mental data are used to estimate the dose under two alternate assumptions of
mode of intake:
.
-
(a) all of the intake was by inhaletion, and (b) all of the
'
:
intake was by oral ingestion.~ It is concluded that the most probable dose to
: the thryoid of a 4 - 4 year old girl is in the range 7OO - 1400 rad.
