This article covers the issues of safety and security of airports in Poland against the CBRNE threat in the form of an explosive device containing a chemical, biological or radiological agent. Airports use advanced technologies to provide them with a high level of protection. The article is an attempt to show the security assurance system in the area of airports as well as the characteristics of an act of unlawful interference using explosive equipment containing chemical, biological or radiological agents. This article uses the method of document research and a review of scientific literature on the airport security system. The state of knowledge regarding the nature of the threat of explosive devices containing chemical, biological and radiological agents justifies undertaking research to characterize the threat in question, airport security and taking action to determine the directions of changes, as well as future solutions to ensure effective airport security. Undertaking this important research problem is justified by the needs of both theory and practice. Theoretical reasons in favor of starting work result from the lack of in-depth studies on the nature of the threat in the form of explosive device containing a chemical, biological or radiological agent and the organization of airport security, the purpose of which is to prevent acts of unlawful interference. Practical considerations are determined by the real threat of using explosive devices containing chemical, biological or radiological agents, which poses a threat to the functioning of airports in Poland and in the world. Security services at the airport, which, despite having specialized equipment and knowledge of conducting radiometric control or mine and pyrotechnic activities, are aimed at counteracting the illegal transport of radioactive materials across the border and recognizing and neutralizing classic explosive devices. The assessment of the possibility of using explosive devices that may contain chemical, biological or radiological agents is treated in the above-mentioned services as the theory of the "black swan". The aim of the article is to present the organization of airport security in Poland against the threat in the form of a device containing a chemical, biological or radiological agent, which certainly pose a serious threat and at the same time a challenge to airport security services.
