damage and has the potential to kill far more people than a dirty bomb ever could.
Conceptually, a dirty bomb (or radiological dispersion bomb) is a very simple device. It's a conventional explosive, such as TNT (trinitrotoluene),
packaged with radioactive material. It's a lot cruder and cheaper than a nuclear bomb, and it's also a lot less effective. But it does have the
combination of explosive destruction and radiation damage.
High explosives inflict damage with rapidly expanding, very hot gas. The basic idea of a dirty bomb is to use the gas expansion as a means of
propelling radioactive material over a wide area rather than as a destructive force in its own right. When the explosive goes off, the radioactive
material spreads in a sort of dust cloud, carried by the wind, that reaches a wider area than the explosion itself.
