A dirty bomb, or radiological dispersion device, is a conventional weapon equipped with nuclear material. The idea behind a dirty bomb is to blast radioactive material, such as powder or pellets, into the area around the explosion. Citing Saudi intelligence sources, Asharq al-Awsat reported Friday that the Iridium-192 was stolen as it was being transported from the Bushehr facility. The vehicle carrying the nuclear material was later found abandoned with its contents seized. It remains unclear who stole the nuclear material and for what purpose.“ (Bericht in der Jerusalem Post: „Report: Nuclear material said stolen from Iran could yield ‚dirty bomb‘“)
