207/Bi was usually below detection limits by gamma spectrometry. Over
70% of the whole-body activity of /sup 207/Bi in goatfish is associated
with the muscle tissue, whereas less than 5% is found in the muscle of
mullet and surgeonfish. Neither /sup 239 +240/Pu nor /sup 241/Am is
significantly accumulated in the muscle tissue of any species of fish.
Apparently, /sup 238/Pu is in a more readily available form for
accumulation by fishes than /sup 239 +240/Pu.
Based on a daily
ingestion rate of 200 q of fish flesh, dose rates to individuals
through the fish-food ingestion pathway are well below current Federal
guidelines.

Abstract: The super-hydrogen bomb test explosion, the so-called Bravo test
of a fission-fusion-fission bomb, was carried out on Bikini Atoll in
the mid-Pacific on March 1, 1954. Twenty-three Japanese fishermen on
board a fishing boat about 90 miles north-east of the test site were
attacked unexpectedly by the fallout, radioactive fine debris of coral
reef. Within several months after the accident by radiochemical
analysis
about 20 different nuclides of fission products
and,
in
addition, Bb considerable amount of /sup 235/U were discovered from the
fallout. As we have been preserving a minute amount of the original
fallout dust collected on board the fishing boat 31 years ago,
measurements of ..gamma.. rays from it have recently been used to find
