On May 19-20, 2023, the Department of Disaster Medicine and Emergency Assistance of the Collegium Medicum of the Jagiellonian University held a training on how to deal with a patient contaminated with the CBRNE agent. Our guests were the medical staff of KYIV EMERGENCY AND MEDICAL CATASTROPHE CENTER. We were also visited by the CBRN MODULE with the Mobilab reconnaissance and measurement car from the KRAKÓW 6 Specialist Chemical and Ecological Rescue Group. It was an extremely valuable exchange of experiences. The course took place as part of the project “Strengthening CBRNE safety and security – Coordination and Standardization” funded by the Norwegian Financial Mechanism 2014-2021.
