A description of the role played by diffusion, ion drift and nuclear recoil in the process of deposition of thoron daughters on solid surfaces is presented. Such a description and the origin of "surface located" and "recoil injected" form of deposit is supported by the results of experiments in which the kinetics of ion drift of 216 Po(ThA), yields of 208 Tl(ThD) recoil emission from thoron daughter deposits and not dissolved fractions of the activity of the daughter were measured.
