The European Society for Isotope Research (ESIR) was founded in 1992 in Wroclaw, Poland to promote scientists who are engaged in isotope research for cooperation and scientific exchange. The Society has been established in many isotope laboratories and institutions in countries from Central and East Europe, but also members from West European countries and from overseas belong to the ESIR.
The ESIR meets every two years since 1992 for a workshop like conference. The meeting is unique in that it provides the opportunity to develop cooperations and discussions between researchers from Central and Eastern Europe with other areas.
During the last conference in Leipzig the General Assembly of the ESIR decided to organize the next meeting in 2007 in Romania. Therefore, the National Institute for Research and Development of Isotopic and Molecular Technologies (INCDTIM), from Cluj, is organizing the ESIR IX Workshop in 2007.
INCDTIM was founded in 1950. At the beginning, the institute was a section of the Institute of Atomic Physics from Bucharest. In 1970, became administratively independent under the denomination of Institute of Stable Isotopes and in 1977 changes its name in Institute of Isotopic and Molecular Technology. In 1999 the institute was certified as "NATIONAL INSTITUTE".
