counts taken on the 74th post-exposure, and none of
these values had returned to control levels. Studies of
bone-marrow specimens revealed no significant
abnormalities. Minimal amounts of residual radioactivity
were detectable in the urine of approximately 1/3 of the
801.

950. ABSTRACT
The objectives of this study of internal
radioactive contamination are as follows: (1) To
determine the nature and extent of the internal
radiation hazard to human beings exposed to the fall-out
from Bravo Burst.
(2)
To evaluate the contribution of
the internal contamination to the acute and long-term
radiation syndrome.
(3)
To determine the feasibility of
by exposed animals,
food plants,
an internal decontamination therapy program. (4) To
determine the amount and type of contamination sustained
801.

and water of the
contaminated atolls. Evaluation of the internal
contamination of the human beings was made by a study of
the radioelements excreted. Since very little
information is presently available concerning the ratio
of excreted radiocelements to the amount deposited in the
body, it was necessary to base the evaluation on data
obtained from animals that had been contaminated in the
same event. Detailed studies of animal tissues and
animal excreta then provided data on which estimates of
the human body burden were based.
