The general relationship pertinent to the uptake
950. ABSTRACT
of fission products by marine organisms is reported in
order to form a background for more extensive tests on
Wigwam. Gross beta activities, beta absorption curves
and gamma spectra were analyzed, after identification of
the organisms. A radiochemical analysis revealed: (1)
that marine organisms concentrate activity from fallout
fission products in the water by factors of the order of
1000,
(2)
that the partition of fallout
fission products
in the ocean is profoundly influenced by biological
processes and that a purely physical model is inadequate
to predict distribution, (3) that the feeding mechanism
of the organism does not clearly determine the amount of
activity assimilated, (4) that there is evidence of
fractionation of isotopes by different organisms, and
(5)
801.
KEYWORD(S)
that there is
some evidence that
finely dispersed
activity is retained more or less proportionally with
the dry weight of the organism.
