Declines in Radiocesium Concentrations of American Coots Inhabiting a Nuclear
Reactor Cooling Reservoir

a neutron monitor is used to assess exposures in spectral environments
substantially different from that in which it was calibrated, the results can be
seriously affected by its energy dependence.
In such case, characterization of the spectral environment will provide
appropriate corrections for the readings and uncertainties in the results can be
estimated. The multisphere
spectrometer proved valuable for such characterization.
film and polycarbonate track etch personnel dosimeters seem inadequate for use
in this environment. The monomer
holds promise. Both albedo
dosimeters may prove useful if extensive spectral characterization reduces the
uncertainties involved to acceptable limits.
Finally, the survey instruments perform adequately.
A previous analyses using the iterative unfolding code BON, resulted in
different detector response distributions (Sa8). This was attributed to the fact that the data base was not
the same and to the inherent smoothing of the iterative technique.
