Piankton
Amounts of radioactivity per unit of wet weight of plankton in samples from each tow appear in Table 7, and on the
basis of ash weight, in Table 8. This dual analysis is intended to evaluate the appropriateness of the wet basis as
compared to the ash basis in considering the radioactivity of
plankton.
Where simultaneous fine and coarse mesh tows
Table 7.
Gross beta radioactivity of plankton samples in thousands of d/m/g of wet weight
at Enivetok Atoll in 1954-56.
