ESIR - European Society for Isotope Research - is the association of scientists engaged in isotope research, focused primarily on Central and Eastern Europe, but is open to all interested parties from around the world.
Isotopic studies of interest to ESIR include various aspects and applications of natural distribution of stable and radioactive isotopes, such as isotopes in geochemical processes, geosciences, oceanography and meteorology, applications of isotopes in industry, mining, forensics, and various other areas, as well as the development of methods and measurement techniques.

According to the Society Statute, ESIR promotes the exchange of ideas and results of isotope research with the emphasis to isotope geochemistry by organizing regular workshops on biannual basis.
Isotope Workshops take place always in Europe with special care to minimize participation costs.

Scope of the Workshops include:

♦ Isotopes in Earth and Planetary Sciences

♦ Isotopes as Tracers of Past and Present Climatic Changes

♦ Isotopes in Ecological and Environmental Studies

♦ Application in Archeology and Forensic

♦ Applications in Speleology

♦ Isotopes in Hydro(geo)logy

♦ Isotopes in Biology and Medicine

♦ Inert Gas and Radiogenic Isotopes

♦ Methodological and Technical Advances in Isotope Studies

♦ Industrial Applications of Isotopes: Energy and Mining
