A program is presented to compute fallout fission product absorption in an expanding, cooling, uniform field of gas and fallout particles where the rate of fission product absorption is controlled by fission product surface concentrations as given by Henrys law constants and diffusion of these fission products into the fallout particles. The calculations are made a nuclide chain at a time, employing nuclear device and fission product parameters. Program output includes average concentration versus particle size for each absorbed fission product at a pre-selected lower temperature and the amount of that fission product in the gas phase, with an option for the calculation of fission product radial profiles versus particle size.
