Boris Korchilov's Fatal Radiation Exposure, Acute Radiation Syndrome, and the Consequences of a Reactor Cooling-System Failure

This scientific review examines the fatal radiation exposure of Boris Korchilov during the 1961 K-19 nuclear submarine accident. It explores the reported radiation dose, the development and clinical consequences of Acute Radiation Syndrome (ARS), and the role of the reactor cooling-system failure in the accident. The paper discusses the biological effects of extreme radiation exposure, radiation dosimetry, historical accounts of the incident, and the broader implications for nuclear reactor safety, radiation protection, and emergency preparedness. By examining this tragic case, the review highlights the importance of reliable reactor cooling systems, effective radiation monitoring, and protective measures for personnel working in high-risk nuclear environments.
