Radiological Dispersal Devices (RDD) / Dirty Bombs

Radiological dispersal devices (RDD), also known as "dirty bombs," consist of radioactive material combined with conventional explosives. They are designed to use explosive force to disperse the radioactive material over a large area, such as multiple city-blocks. Around the world, there are many sources of radioactive material that are not secure or not accounted for. Rogue nations and/or terrorist groups can obtain these materials for dirty bombs. These explosive weapons may initially kill a few people in the immediate area of the blast but are used primarily to produce psychological rather than physical harm by inducing panic and terror in the target population. Their use would also result in costly cleanup for decontamination.
