SSU Counterintelligence and investigators have documented two new instances of russia’s use of ammunition containing depleted uranium elements against Ukraine. The hazardous components were detected in ‘Geran-2’ strike UAVs, which the ruscists used to attack Sumy region twice in April 2026.

These are R-60M air-to-air guided missiles, which the enemy is using as warheads for their drones during mass attacks on Ukraine.

While the investigative-operational team and State Emergency Service specialists were working at the sites of enemy strikes, the level of gamma radiation from the debris of russian drones carrying missiles was 8.3 and 10.5 μSv/h. These figures significantly exceed the natural background radiation and pose a direct threat to human health.

According to the results of an examination initiated by the SSU, it was determined that the warheads of the russian missiles contain depleted uranium components with a total mass of 2,810 grams. The material was identified as Uranium-234, Uranium-235, and Uranium-238.

Following the identification and examination of the hazardous components, comprehensive measures were taken to neutralize them.

SSU investigators are conducting a pretrial investigation under Article 438 of the CCU (war crimes) to identify and bring to justice the ruscists responsible for the airstrikes.

To note, in April of this year, the SSU’s counterintelligence uncovered evidence that the enemy had used radioactive munitions in Chernihiv region.

Given the danger posed by depleted uranium, citizens are urged to exercise extreme caution if they come across debris from UAVs, missiles, or other weapons.

Under no circumstances should you approach, touch, or move such objects. Move to a safe distance and immediately report the discovery by calling the following hotlines: SSU – 15-16, State Emergency Service – 101, or National Police – 102.

The investigation is ongoing under the procedural supervision of the Sumy Regional Prosecutor’s Office.
