Dirty bombs: The terror and the truth

James Conca
The term “dirty bomb” surfaces occasionally, usually in the context of nuclear waste, which, while understandable, is incorrect.
Dirty bombs, or radiation dispersal devices (RDDs), use conventional methods like car bombs to disperse radioactive materials in populated economic districts, such as lower Manhattan. The point is to cause great economic and social disruption disproportionate to the actual radiological effects—and well beyond the physical destruction from the conventional bomb components.
Society’s irrational fear of radiation makes the dirty bomb an ultimate weapon of terror. But it is a psychological weapon, not a nuclear one. The public should not be any more afraid of a dirty bomb than they are of an ordinary car bomb.
