Comparisons between beta and gamma measurements
were not possible as the absolute values could not be deter-
mined with sufficient precision from the available information.
These measurements, however, may be used for relative comparisons of the data within each class.
All concentrations in the table are expressed in terms
of ash weight.
Corrections based on average wet:dry:ash
weight ratios of large samples from earlier collections were
applied

Gamma spectrometric analyses.
The results of
analyses of gamma spectra between 0.5 and 2.0 mev of pooled
samples from 3 families of fish with the highest levels of
