The Security Service of Ukraine (SSU) counterintelligence officers and investigators have documented six new cases of Russia using munitions containing depleted uranium components in Geran-2 attack drones deployed against the Chernihiv region between April and June 2026.
According to Ukrinform, the SSU reported that its investigation found Russian forces are using R-60M missiles adapted for launch from Geran-2 drones and equipped with radioactive elements.
During inspections of drone impact sites and radiological examinations of the warheads, an investigative team and specialists from the State Emergency Service of Ukraine recorded radiation levels up to 80 times higher than the natural background.
Gamma radiation emitted by individual drone fragments ranged from 8.3 to 24 µSv/h, compared with the maximum permissible sanitary limit of 0.3 µSv/h. According to the SSU, such radiation levels pose a direct threat to human health and the environment.
An expert examination initiated by the SSU determined that the missile warheads contained nuclear material identified as uranium-235 and uranium-238.
