Abstract: In this review methods and practical use of gas radiochromatography are surveyed. In the first part radiochromatographic methods from the viewpoint of radioactivity measurement (discontinuous analysis, continuous analysis, combustion method) and of the radiation detectors used (GM-counters, proportional counters, scintillation counters, ionization chambers) are described. The type of detector used is given by type and energy of radiation, as well as by working conditions of analysis (carrier gas, chemical composition of separated mixture etc.). Each radioactivity detector is suitable for certain group of labeled compounds and radionuclides only. The second part of the paper deals with practical examples of use of gas radiochromatography: analysis of permanent gases, separation and analysis of artificial radionuclides, preparation and analysis of labeled compounds, applications from the field of hot-atom chemistry, investigation of the course of chemical reactions and the use of gas radiochromatography in biochemistry.
