Radioanalytical procedures development
Developments in the past few years have radically changed the requirements of radiochemical separations in radionuclide analyses. Advances in gamma spectrometry, particularly those using multidimensional and solid state Ge(Li) detectors as well as x-ray fluorescence spectrometry have provided selective and sensitive instruments for analysis and have substantially modified the requirements of radiochemical procedures. There is at present an urgent need for procedures that quantitatively separate a radionuclide mixture obtained from natural systems or from one created in the course of elemental analyses such as with neutron activation. The developing techniques are those that divide the mixture into two or three groups or that quantitatively remove an interfering constituent so that the resulting group(s) can be quantitatively measured by instrumental techniques. Procedures have also been developed to measure specific elements such as Hg found to coexist with certain trace radioactive or stable constituents of environmental samples. (auth)
