Question

Quizplus · Accepted Answer

A dirty bomb is a type of explosive device that combines low level nuclear material with conventional explosives. When detonated, the explosion disperses radioactive material into the surrounding environment, making the area contaminated and potentially uninhabitable for a period of time. The use of medical X-rays as a source of nuclear material is unlikely due to the low level of radioactivity they contain, but commercial low level nuclear material could be used. Neither anthrax nor chemical bombs would render an area uninhabitable in the same way as a dirty bomb.
