Summary
On May 20, 2026, Ukraine's Security Service (SBU) reported that an R-60 missile used in a Russian drone attack on Chernihiv Oblast contained depleted uranium. Elevated radiation levels of 12 micro-Sieverts per hour were detected from the missile fragments, which were integrated into a modified Geran-2 drone during an attack on April 6-7. The SBU has secured the missile's warhead and transported it to a radioactive waste facility, warning citizens about the dangers of encountering debris. A pre-trial investigation for war crimes has been initiated under Article 438 of Ukraine's Criminal Code. NATO Secretary-General Mark Rutte emphasized that any use of nuclear weapons by Russia would provoke a devastating response from NATO. The situation remains critical as Russia conducts joint nuclear drills with Belarus amid rising tensions. Key Points: • Depleted uranium was found in a Russian missile used in a drone attack on Ukraine. • Radiation levels detected were significantly above natural background levels, posing health risks. • A pre-trial investigation into potential war crimes has been launched by Ukrainian authorities.
Detailed Analysis
**Impact** The attack affected Ukrainian military and civilian areas in Chernihiv Oblast, specifically near the village of Kamka, with elevated radiation detected from missile debris. The use of depleted uranium warheads poses health risks to personnel and civilians due to radioactive contamination, with gamma radiation levels recorded at 12 microsieverts per hour, exceeding natural background radiation. This introduces long-term environmental hazards and complicates cleanup and recovery operations. There is no information on data loss or direct impact on business sectors. **Technical Details** Russian forces deployed modified Geran-2 drones armed with unexploded R-60 air-to-air missiles containing depleted uranium (Uranium-235 and Uranium-238) projectiles. The attack vector involved air-launched missile strikes targeting Ukrainian helicopters and aircraft conducting air defense missions. Radiation reconnaissance detected hazardous gamma radiation from missile fragments, indicating the use of radioactive materials as penetrating warhead elements. No malware, CVEs, or cyber infrastructure details were reported. **Recommended Response** Personnel should avoid contact with missile or drone debris, especially damaged or burnt munitions, to prevent exposure to radioactive dust. Radiation detection and monitoring should be intensified in affected and adjacent areas, with secure transport and storage of contaminated materials in designated radioactive waste facilities. Ukrainian defense and emergency services should continue coordinated investigations and public warnings. No specific cybersecurity mitigations are applicable based on available information; monitoring for further use of radioactive munitions is advised.
