A "dirty bomb" is one that generates and/or leaves behind it a great deal of long-term radiation. No 'dirt' is required. A "clean bomb" is a type of bomb that just goes bang and blows stuff apart. An example of a clean bomb is the neutron bomb. A neutron bomb kills only living things like grass, trees, animals, and persons. It does little or no harm to buildings, cars, houses, and subways. They are harmed only if they are close to the explosion. The radiation and harmful products of a dirty bomb may cover dozens, hundreds, thousands, and millions of square miles -- and, indeed, the entire globe.
