On September 16–17, 2024, a RODOS User Group meeting took place at the National Centre for Nuclear Research (NCBJ) in Otwock-Świerk, near Warsaw. 45 people attended the meeting in person, and 30 participated remotely. The purpose of the meeting was to facilitate the exchange of experiences among RODOS User Group members and to discuss ideas for enhancing the RODOS system and its future development.

The RODOS (Real-time On-line Decision Support) system is an advanced tool used in crisis management during nuclear and radiological accidents. Its main function is to provide comprehensive and up-to-date information necessary for making decisions regarding the protection of the population in the event of a release of radioactive materials. The RODOS system integrates meteorological, environmental data, and pollution spread models, enabling rapid forecasting of the effects of an accident and recommending optimal remedial actions. It is utilized by institutions and organizations responsible for crisis management at regional, national, and international levels, including operational centers of the federal government and individual states in Germany. The development of the RODOS system began in the early 1990 s and has been installed in many European countries, including Poland, the Czech Republic, Slovakia, and others. Its latest versions are used in many European crisis management centers.

During the meeting, participants focused on improving the RODOS system, enhancing its integration with national crisis management systems, and sharing valuable experiences. The exchange of knowledge, improvement of the system’s usability, and discussion of the latest technical and organizational solutions aimed to increase the effectiveness of RODOS in nuclear crisis management in Europe. The meeting ended with a training session on the JRODOS system.

The meeting provided an excellent opportunity for cooperation, knowledge exchange, and strengthening partnerships to ensure the sustainability and flexibility of the RODOS system in the future.
