Abstract: | Two methods for chemical yield measurement of Se in biological samples after radiochemical neutron activation analysis when using the75Se nuclide are described, namely a Spectrophotometric technique and a radiotracer technique employing81mSe. These two approaches were compared and evaluated by applying them to the analysis of Se in various certified reference materials. |
