PJ:

The neutron bomb was actually a very "clean" bomb as oppesed to a "dirty" bomb. It was designed to release a strong burst of neutrons (in the form of radiation) which would kill organic life, but it was designed to have very little blast effect which would destroy property and very little fallout and secondary radiation which owuldcontaminate property. It never went beyond the design stage and, perhaps never even got to the design stage. It was never oeprational.

Actually you would never have had a "big" neutron bomb. In order to have the killing power without the blast and vaporization which would result in fallout, they would have had to remained realtively small bombs.
