Depleted uranium elements on the debris of a Russian UAV: what is known from the SSU and the State Nuclear Regulatory Inspectorate
The Security Service of Ukraine (SSU) recorded an elevated radiation background of about 12 µSv/h (with a norm of up to 0.5 µSv/h) on the debris of the russian ‘Geran-2’ drone that attacked the Chernihiv region in April 2026. The warhead, which contained depleted uranium elements, was safely removed and transported to a radioactive waste storage facility.
The State Nuclear Regulatory Inspectorate of Ukraine (SNRIU) explained that the main danger of such debris does not lie in external exposure, but in the toxicity of its dust upon contact with a person.
«The risk of external radiation exposure to the public from solid depleted uranium products is low. However, there is a potential risk of internal exposure in the event of direct human contact with dust or aerosols due to the presence of alpha and beta radiation, and radioactive contamination could enter the body through the air, water, food, or wounds».
The SSU and the SNRIU urge Ukrainians to adhere to strict safety rules when discovering debris from UAVs, missiles or other munitions.
- Do not approach the discovered object.
- Do not touch or attempt to move the debris.
- Step back to a safe distance to avoid contact with potential radioactive dust.
- Immediately notify emergency services by calling: 101 (State Emergency Service), 102 (Police) or 15-16 (SSU hotline).
Due to russia’s use of depleted uranium munitions against Ukraine, SSU investigators have opened criminal proceedings under Article 438 of the Criminal Code (war crimes).
