Introduction: The use of radiation sources in various areas of life generates the risk of accidents and radiation disasters. The increase in terrorist threats as well as the risk of an outbreak of new armed conflicts carries the risk of using radioactive materials by terrorist groups and the military. Exposure to high doses of radiation and absorbing above-threshold doses by victims may cause acute radiation syndrome (ARS), as well as some distant effects. Personnel of the State Emergency Medical System (EMS) will be the first professional medical team in the process of providing assistance to such victims. The effects of further medical treatment in the hospital will depend on EMS’s first response, radiological triage and initial interventions taken. The aim: To present pathophysiology and clinical symptoms of acute radiation syndrome in the context of the medical practice of the EMS. Material and methods: For the purpose of this publication, an analysis of literature on the subject of the mechanism of ionizing radiation and its effects on the human body was performed. The work is focused on the interpretation of research results and their presentation from the EMS’s perspective. Results: The publication presents the impact of ionizing radiation on the body, the mechanism of damage to cellular structures and its consequences for individual organs and systems. ARS’s clinical (hematopoietic, intestinal, cerebrovascular) syndromes were discussed in detail, paying attention to radiation doses, the sensitivity of individual systems and organs, the dynamics of individual phases, as well as the ability to recognize and assess the severity of their progression by EMS personnel. Conclusions: The knowledge of pathophysiology, and ARS’s symptoms and dynamics is important to respond correctly to radiation incidents. This knowledge allows for efficient organization and emergency management during rescue operations. The increase in the risk of radiation incidents and radiation disasters generates the need for appropriate preparation of emergency rescuers, in particular, of the medical personnel of the State Emergency Medical Services.
