Table III. I. Kinds of analyses reauired Gamma counting A. _ 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.
