en عمومى General مروری Review <div style="text-align: justify;"><strong>Background</strong>: Chemical, biological, radiological, and nuclear (CBRN) threats present complex challenges to global security and public health. Scholarly attention to these threats has increased significantly over the past decade, particularly following global crises, such as the COVID-19 pandemic. However, systematic evaluations of research patterns, collaborations, and thematic developments remain limited. This study addressed this gap through a bibliometric analysis of global CBRN scholarship.<br> <strong>Materials and Methods</strong>: A total of 132 peer-reviewed journal articles (2010&ndash;mid-2025) were collected primarily from Web of Science and Scopus. A supplementary PubMed search yielded no additional unique records. To ensure reproducibility and metadata reliability, general search engines and domestic databases were excluded. Bibliometric mapping, including co-authorship, institutional collaboration, and keyword co-occurrence analyses, was conducted to explore intellectual structures, thematic evolution, and geographical patterns.<br> <strong>Results</strong>: Of the 1420 initial records, 1210 were screened, and 132 studies met the inclusion criteria, following PRISMA 2020 guidelines. Analyses using R (bibliometrix/biblioshiny) and VOSviewer showed a significant increase in CBRN research after 2015, peaking during the COVID-19 period. The United States and United Kingdom led global collaboration networks, while contributions from Global South countries increased diversity. Keyword trends shifted from decontamination-focused studies to artificial intelligence, simulation-based preparedness, and governance frameworks.<br> <strong>Conclusion</strong>: CBRN research has developed into a mature and diverse field. Promoting interdisciplinary collaboration, equitable knowledge access, simulation-based preparedness, and stronger science&ndash;policy integration is essential for effective global security strategies.</div> CBRN threats, Bibliometric analysis, Global health security, Research trends, Public health 5 18 http://hdq.uswr.ac.ir/browse.php?a_code=A-10-712-1&slc_lang=en&sid=1 Tuncay Polat tpolat@erzincan.edu.tr 0000-0002-1066-8886 Yes Department of Property Protection and Security, School of Health Services Vocation, Erzincan Binali Yıldırım University, Erzincan, Türkiye.
