Tykhenko O. Methodological and technological fundamentals of workers protection from exposure to electromagnetic fields by the means of metal and composite screening materials

The dissertation to obtain the academic degrees of the Doctor of technical sciences on the specialty 05.26.01 – occupational safety. State Higher Education Establishment "Donetsk National Technical University", Pokrovsk, 2021. The dissertation is devoted to solving the scientific and practical problem of increasing the electromagnetic safety of workers by determining the conditions of maximum efficiency of metal shielding materials, development and implementation of highly effective composite materials for shielding electromagnetic fields of wide frequency range and regulatory requirements in the industrial environment. The analysis of the existing approaches to ensuring electromagnetic safety of workers is carried out. It is established that the most effective means of reducing the levels of electromagnetic fields in the production environment is their shielding with innovative composite materials that can be used for the manufacture of individual and collective protection. The amplitude-frequency dependences of the shielding coefficients of magnetic and electromagnetic fields of the most common frequencies and frequency ranges were studied, and methodological bases of application of metal electromagnetic screens made of crystalline and amorphous alloys were developed. The conceptual foundations of protective clothing design for personnel servicing electrical equipment and radio engineering objects. The algorithms for the processes of design, testing and implementation of protective screens and shielding constructions are provided, which will increase the efficiency of implementation of labor protection measures for shielding magnetic and electromagnetic fields.
