The application of radioisotope techniques in the chemistry and technology

The research work of the ''Laboratorium fuer Isotopentechnik'' of the Nuclear Research Centre, Karlsruhe is rewieved. Some of the most important works are treated in details: investigation of the corrosion process in aqueous/solid interfaces; optimization of apparatus and processes in the technology: investigations of instationary two-phase systems; determination of mass-flow parameters; process analysis using 252Cf-neutron activation analysis techniques and X-ray fluorescence analysis; neutron activation analysis using reactor and/or neutron generators. For full details the appropriate references are given. (T.G.)
