Abstract
A theoretical study has been made of droplet formation in hot vapour gradually cooled under admixture of air containing particles. Spontaneous nucleation, condensation on existing droplets, and coagulation are treated as simultaneous phenomena. Spontaneous nucleation takes place initially, but gives way to condensation on existing droplets. For nuclear ground explosions, site particles are present in the admixed air. Bomb debris is therefore composed of one particle group developed from spontaneous nucleation and another group strongly affected by admixed particles. Only the latter group contains particles large enough to produce close-in fallout. Its radioactivity size distribution is approximately the admixed particle-number size distribution weighted by linear size raised to a power between 1·1 and 1·5.
