What is the 'dirty bomb' that Russia claims Ukraine will use?

Washington [US]: US State Secretary Antony Blinken spoke with Ukrainian Foreign Minister Dmytro Kuleba on Tuesday and reaffirmed his country`s support for the war-ravaged nation as Russia continues to draw global attention to what Kremlin says is Kyiv`s plan to use "dirty bombs" as a propaganda tool against Moscow." Secretary of State Antony J. Blinken spoke today with Ukrainian Foreign Minister Dmytro Kuleba. The Secretary reaffirmed enduring U.S. support for Ukraine in the face of continued Russian aggression, atrocities, and rhetoric surrounding so-called "dirty bombs" in Ukraine," said State Department Spokesperson Ned Price. This phone comes amid Russian claims that Ukraine is preparing to use a dirty bomb, which is reportedly a mix of explosives with radioactive materials.

A dirty bomb is a mix of explosives, such as dynamite, with radioactive powder or pellets. When the dynamite or other explosives are set off, the blast carries radioactive material into the surrounding area. "A dirty bomb works completely differently and cannot create an atomic blast. Instead, a dirty bomb uses dynamite or other explosives to scatter radioactive dust, smoke, or other material in order to cause radioactive contamination," according to US Centers for Disease Control and Prevention.

The world would see through any attempt to use this allegation as a pretext for escalation. We further reject any pretext for escalation by Russia."

Meanwhile, Russia has asked UN chief Antonio Guterres to do everything he can to prevent Ukraine from carrying out its "dirty bomb" provocation."
