On Function of Distribution of Uranyl-Fluoride Aerosol Particles under Condition of Everyday Production Activities at Sublimate and Concentrating Plants of Atomic Industry

It is shown that if in the process of aerosol systems creation, which accompanies the hydrolysis of hexafluoride of uranium in the atmosphere of working rooms of concentrating plants, the lognormal radius distribution of aerosol particles appears, then it maintains even in the case when particles are already involved into the process of forming a sediment on production surfaces under the influence of Earth’s gravitation field. It is proved for the case when hexafluoride of uranium appears in the working room air during everyday production activities. A continuity equation is solved for the system of gas and aerosol products of hydrolysis. The specific (by radiuses of aerosol particles) concentration of molecules of the substance under interest in the composition of aerosol particles having a certain radius is calculated as well as a function of radius distribution of aerosol particles. A conclusion is made on the distribution function form for various values of a coefficient of air exchange in the working room.
