Some of the population exposure pathways from radioactive releases are: external exposure from contaminated underlying surfaces; internal exposure from consuming contaminated food. The article examines the influence of dry and wet deposition factors during continuous release on population exposure along the indicated exposure pathways. A quantitative assessment of the ratio of contributions from dry and wet deposition to population exposure along these exposure pathways is given, depending on the main parameters and the distance from the source. It has been shown that under certain conditions, critical points on the terrain at which the total dose and the dose for each of the main exposure pathways reach a maximum may not coincide. Options for considering the identified fact in calculating limits for radioactive releases to air are proposed.
