Most of the nuclear fallout on a nuclear explosion is from detonating at or near ground level which turns the dirt and dust around there radioactive while blasting it high into the air. An air burst bomb only has the radioactive material that failed to explode in the bomb, and like someone else mentioned that is easy to deal with and isn't a real big problem in the first place unless you intentionally are making your bomb inefficient and dirty.
