ABOUT CALCULATION OF THE DETERMINISTIC EFFECT OF PROTEINURIA IN EMPLOYEES OF ENRICHMENT PLANTS OF NUCLEAR INDUSTRY

Abstract

In this paper, we consider the impacts of gaseous uranium hexafluoride used at concentrating plants of the nuclear industry on the human body. The appearance of uranium hexafluoride in the air of the working premises is accompanied by hydrolysis and the formation of substances that can enter the human body and bring atoms of uranium and fluorine. The article describes the method of the determination of the working conditions preventing the development of occupational diseases in employees. The method is based both on the calculation of the number of toxic substances entering the human body in routine working conditions and comparison of this number with the threshold values for different deterministic effects. The proteinuria (protein content in urine) is selected as the considered deterministic effect. We used the published statistics on the threshold of the daily release from the human body toxic substances, long-entering the body in small doses and seem to be responsible for the occurrence of urologic diseases. The calculation was performed in the framework of a complex model describing the air pollution with products of hydrolysis of uranium hexafluoride entering of toxic substances in the human body, in working premises, as well as the passing of uranium and fluorine through the body. This model constructed by the authors of this article was described in previous publications. To ensure that the theoretical methods give the same results as the experimental, the results obtained by the standard method for employees of one of the enterprises of nuclear industry were compared with the data obtained using the theoretical method under the same working conditions. The considered theoretical method can complement and enrich the existing experimental methods for the identification of the onset of occupational diseases based on the sampling of different biomaterials from the employees working at enterprises.
