About 500 nuclear weapons were exploded in the atmosphere worldwide prior to the nuclear test ban treaty, with a total yield expended of more than 400 Mt. Of greater relevance here, 100 airburst weapons with an average yield 20 of 10 kt were detonated over the Nevada test site (NTS). About 61 of these devices had a high enough yield to produce measurable radioactivity beyond the NTS Bouville et al., 2002). The tests were deliberately conducted in locally dry onditions, so that the debris would remain aloft as long as possible, decaying and dispersing before returning to the surface.
