The plankton samples analyzed thus far also reflect the
levels of activity in the water mass in which the plankton
were collected.
The concentration factors calculated on
the basis of amounts of pu239,240 in the water and in a
corresponding weight of plankton were remarkably uniform.
The concentration factors ranged from 2.4 x in? to
Plankton samnles analyzed thus far averaged 3 x 104 x
These
concentration factors appear to he high by approximately a
factor of 19 over those generally reported in the literature.
