they showed no other evidence of disrane.
Autopmy of two chickens which died during
shipment revealed no pathological findings that
could be associated with radiation.
On the basis of an assumed 12-hour effective
fallout time, the animals from Rongelap received an integrated external dose of 2s to
360 r, depending on the date of their collection
(see Table 5.7). The pigs from Utirik received
a calculated dose of 32 r at the time of their
evacuation. The animals all showed extensive
external contamination, ranging from 0.5 to
> mr per hour at 4) days post detonation. This
activity was reduced about 75 percent by a

(irose beta and gamma activity of the chick-
ens at +4 days post detonation was approsi-
mately 0.2 pe.
The gross activity per bedy
weight of the chicken is approximately the same
asthat ofthe pig. The distribution of activity
in the timues of the chicken (Table 5.9) was
very similartothat inthe pig. Most respiratory
radio activity was localized in the turbinates,
asa result of entrapment of the large particles,
which could not penetrate to the alveolar tissue.
The beta activity in the skeleton of chickens
at 160 days dropped to + percent of the value at
24 days post detonation, while in the same perio the gamma activity dropped to 0.2 percent
gross beta activity of the pigs at 82 days post
