-18Plankton
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 considerin g the radioactivity of
plankton.
Where simultaneous fine and coarse mesh tows
Table 7.
Gross beta radioactivity of plankton samples in thousands of d/a/g of wat weight
at Eniwetok Atoll in 1954-56.
