goadioh caught at Kabelle [stand
The radioactivity in muscle tissue
was reneraliy about the same in Kabelle and Enibuk reef fish.
Gamma radioactivity in (he muscle averaged about 26 per cent that
of the liver with variation of from 7 io 48 per cent.
Beta activity was
Slightly lower, the muscle to liver ratio averaging about 1°
with a range of from 5 to 27 per cent.
er cent,
The greatest difference in the
arounts of both gamma and beta radioactivity between liver and muscle
was found in the zoatfish.
Gamma Spectra
Gamma spectra were made on dried samples of tissue to determine
if gamma peaks other than those from expected fission products were
present.
The

obtained from various fiah
tissues are compared with spikes of radioactive cobalt and radioactive
zinc in Figure 3 (top, center panel)
The gamma spectra (made in October 1957) on whole
exhibited certain common
characteristics
