In the article, with the aim of assessing professional risks associated with X-ray radiation during the production of titanium ingots, the logical-graphical risk analysis method known as Event Tree Analysiswas used. Event Treeis modeled on the basis of inductive procedure of evaluation of possible causes of X-rays having harmful effects on the body of workers during production of titanium ingots in electron beam furnace, as well as causes of harmful effects on the body of workers in this production. The mathematical dependence of X-ray radiation on electric and magnetic fields has been established. The analysis of data and graphical representation of the dependency demonstrates a clear connection between X-ray radiation and the levels of electric and magnetic fields. The results obtained confirm that an increase in the intensity of these fields leads to an increase in X-ray radiation. In this regard, the upper level of the Event Treeas a factor of increased levels of electric and magnetic field intensity confirms the importance of taking these factors into account in risk assessment and forecasting of working conditions. To verify the accuracy of the model, validation was performed using statistical data. Graphical analysis showed a correlation between the intensity of electric and magnetic fields and the level of X-ray radiation, which was confirmed by the obtained dependence. A brief description of the named production is presented. Information is provided on the effect of X-ray radiation on the employees body. The main conclusions highlight the need to use modern personal protective equipment to minimize professional risks. A comparative analysis of the choice of personal protective equipment (PPE) was carried out using the current approach according to intersectoral standards and a new risk-based approach. To improve working conditions in the workplace, it is recommended to use the following PPE as relevant protection against X-ray exposure: helmet, safety glasses, filter masks, insulating protective suit.
