On December 9-10, 2022. In 2018, another (No. 2) workshop was held for the medical staff of the Polish Center for International Aid (PCPM) at the Department of Disaster Medicine and Emergency Assistance of the Jagiellonian University Medical College. Radioactive agent detection, radiation classification in the emergency department, prehospital medical decontamination, removal of a biologically contaminated and highly infectious patient from the scene of a CBRNE event were practiced together. These were two days of very intensive practical classes. We would like to thank the participants for their participation in the workshops and their commitment during their implementation.
