The article is devoted to the problem of assessing the degree of influence of a complex of factors of various origins on the health of workers engaged in the production of titanium alloys. The focus of this study is to build a predictive regression model of multifactorial
effects on the formation of diseases of the circulatory system in workers. Two groups of factors are considered: non-industrial factors (behavioral and individual), and industrial (toxic substances, aerosols, mainly of fibrogenic action, electromagnetic fields (EMF),
increased noise and vibration, unfavorable microclimate parameters, etc.). A model for predicting the probability of developing diseases of the circulatory system of high quality with a coefficient of determination R2 = 0.82 is constructed. The model includes the combined effect of work experience in harmful working conditions, EMF, the presence of aluminum and its alloys in the air of the work area, as well as elevated temperatures. The use of the multiple linear regression method in the analysis of statistical relationships between the influencing risk factors and the morbidity of workers in specific professions has allowed us to identify the leading factors with the greatest contribution to the development of pathology and can be recommended for solving practical problems of occupational medicine.

HEALTH OF WORKERS UNDER CONDITIONS OF EXPOSURE TO NON-IONIZING ELECTROMAGNETIC RADIATION

A. M. Kononova

The article presents an analysis of the impact of non-ionizing electromagnetic radiation (NEMR) on the health of workers. The study identified the most common pathologies among workers exposed to NEMR and assessed the effectiveness of existing protection methods. Analysis of data obtained from various scientific studies allowed us to systematize information on the impact of NEMR on the human body and identify gaps in existing safety measures. The findings of the study indicate the need to optimize safety measures to improve working conditions and reduce the risk of developing diseases associated with exposure to NEMR.

SYSTEMIC APPROACH TO MANAGING PROFESSIONAL RISKS FROM IONIZING RADIATION

D. A. Pozdeeva

The article presents the theoretical foundations of the process of occupational risk management in workplaces with an ionizing radiation exposure factor. The place of a special assessment of working conditions in the process of identifying occupational risks is considered. A two-component model of factors influencing the level of professional risks of employees has been developed. An assessment of occupational risks by the Fine-Kinney method is proposed.

AUTOMOBILE LOAD ON RESIDENTIAL NEIGHBOURHOODS IN RUSSIAN CITIES

The aim of the study is to assess the impact of motor transport on the modern landscape of residential areas of urban development. In nine cities, that are large administrative centres, 50 sites with a total area of about 500 thousand m2 were surveyed. In each city, on 4-6 experimental sites, representing several multi-storey apartment buildings with a common courtyard, as well as the adjacent part of the street, the number of parking spaces and the number of parked cars were calculated, the areas occupied by organised and unorganised parking were estimated. According to the survey results, it is obtained that on average 37 % of cars are parked in yards and 10 % of cars on the adjacent street road network. From 3 % to 22 % of cars are parked in unorganised parking lots (on lawns, playgrounds, etc.). Car parking is associated with the formation of disturbed areas, which are a source of dust and surface sediment production. The presence of motor vehicles in the courtyards of Russian cities is a significant factor reducing the quality of the urban environment.
