In general, no dissolution nor chemical separation will be required
‘prior to gamma spectrometry.
There could be occasional exceptions
to this rule, e.g., sea water will require processing.
It is expected that essentially all samples willbe gamma counted.
In many cases, this may be the only analysis required.
Nuclides which are expected to be observed and which can be quantitatively measured by gamma spectrometry:
