Inhaler injection and injection through skin of toxic substances in a human organizm under regular industry conditions at factories of nuclear industry

We consider the process of leakage of uranium hexafluoride in air of a factory shop on a factory of nuclear industry. We propose a mathematical model describing the appearance of products of hydrolyze and coagulation of $\mathrm{UF_{6}}$ in air of the shop. This model accounts the diffusion of molecules of gas and aerosol particles and drift of aerosol particles under the action of gravity and viscous forces. We estimate doses of toxic substances (uranium and fluorine) obtained by a person during a given time interval.
