Abstract
Taking into account the world trends in the production and use of stable isotopes of light chemical elements, the main directions of their application and the scale of modern production are considered. Particular attention is paid to stable isotopes, mainly used in clinical medicine and various biological studies. At examples for isotopes of 13C, 18O and 15N are analyzed the change in the production volume of isotope products by years, the technologies used for isotope enrichment are considered and manufacturers in different countries of the world are indicated. Particular attention is paid to the appearance of relatively new industrial processes for the enrichment of 13C and 18O. The dominant role of physicochemical separation methods in the production of light isotopes is noted. In addition, from the technology development point of view, technical proposals for the improvement of physicochemical separation methods aimed at enriching 15N and separation of boron isotopes are considered.
