Mathematical Description of Processes of Emerging and Depositing of Hydrolysis Products of Gaseous Uranium Hexafluoride UF6 in Flat Layer and in Tube

A problem of estimation of doses of toxic substances - uranium and fluorine in production conditions of handling uranium hexafluoride UF₆ is solved. The discussed mathematical model takes into account the diffusion motion of particles in gas phase and drift movement of aerosol particles under gravity. The movement is considered in a flat layer. Such a model is maximally approximated to the described physical process and allows one to estimate doses being received by a person through inhaling toxic substances and due to their deposition to the person’s skin.
