[en] Full text: During the last year, our Department has been divided into three groups: basic research, ecology and medical physics. The basic research group was concentrated on the intermediate energy physics (production and properties of a₀ meson and heavy strange hyperons, rare pion decays and neutrino physics) in close collaboration with KFA Juelich (Germany), PSI Villigen (Switzerland) and ICARUS project (Italy), theoretical and experimental (in LNS Italy) studies of heavy ion interactions, nuclear spectroscopy (in collaboration with CERN Switzerland, NFL Sweden, YFL Finland, GANIL France and SLCJ in Warsaw) and atomic physics (in collaboration with PSI Switzerland). The ecology group continued measurements of the radioactive contamination of our environment, and in particular the ground level air pollution in Poland, Russia, Ukraine and Spitzbergen where a new, constructed in our Department air collection station is working now. The group is concentrated also on the preparation of the ''Intelligent Air Monitoring System for Environmental Control and Management'' project for the FP6 of the European Union. Our medical physics group continued development of the so called photon needle for the applications in the brachytherapy of brain tumors. Financial support of the State Committee for Scientific Research and Maria Sklodowska-Curie Polish-American Foundation is acknowledged. (author)
