The need to develop and implement a strategy for chemical, biological, radiation, and nuclear safety in Ukraine in the context of contemporary global challenges and conflicts

The article is devoted to a comprehensive analysis of threats to Ukraine's chemical, biological, radiological, and nuclear (CBRN) security in the context of ongoing armed aggression, accompanied by an increased risk of the use of unconventional weapons and hybrid forms of influence. The relevance of the research is determined by the transformation of modern military conflicts, in which CBRN factors are increasingly used not only as a means of physical damage, but also as an instrument of political pressure, psychological influence, and destabilization of the state management system. An additional factor contributing to the relevance of this research is the lack of a comprehensive, institutionally integrated approach to the formation of a unified CBRN security system in Ukraine, as well as the fragmentation of regulatory, legal, and organizational support in this area. The purpose of this article is to comprehensively reveal the nature, structure, and dynamics of CBRN threats to Ukraine's national security, assess their escalation potential in the context of full-scale war, and provide scientific justification for the need to create an integrated national response strategy. The research uses methods of systemic and structural-functional analysis, comparative assessment, analysis of open sources, as well as a study of the current regulatory and legal framework and practices of interagency cooperation. The main results of the research are the identification of key risk factors for CBRN threats related to enemy actions, the vulnerability of critical infrastructure, the limited capabilities of monitoring and response systems, and insufficient coordination between military and civilian structures. Systemic and organizational shortcomings in the state system for ensuring CBRN security have been identified, and existing signs of the enemy's readiness to use unconventional weapons as an element of hybrid warfare have been summarized. The practical significance of the research lies in the formation of scientifically sound approaches to the development of a state strategy for CBRN security aimed at comprehensive risk management, strengthening interagency coordination, and increasing the level of preparedness of Ukraine's defense forces and civil protection system to counter threats of chemical, biological, radiological, and nuclear origin.
