Purpose. Determining the levels of environmental pollution by electromagnetic sources and providing recommendations on how to prevent the impact of negative factors on human health. Design/methodology/approach. Particular attention is paid to the spread of electromagnetic fields within the urban system of Kremenchuk, namely from household sources, which include cellular communications and WiFi wireless communications. These products have recently become extremely widespread, without taking into account their total impact on the environment and human health. Therefore, the authors tried to conduct experiments both in the homes of city residents and in their leisure cities. Determination of levels of pollution by electromagnetic sources is carried out using numerical values of energy flux density in μW/cm2, for this purpose is carried out using direct instrumental measurement with the device ATT-2592. This device is designed to determine the level of the electromagnetic background, the principle of which is based on the isotropic method of measurement. Conclusions. An algorithm for organizing observations of the level of background characteristics of the electromagnetic field (EMF) within the urban system is proposed. Limitations/consequences of research. The proposed algorithm is universal and can be used in various fields of production and management to determine the levels of environmental pollution by electromagnetic sources. Practical consequences. An algorithm for determining the levels of environmental pollution by electromagnetic sources within the urban system has been developed. Originality/meaning. According to the study, there is no acute negative impact on the health of residents of a certain group in the urban system, however, the issues of chronic negative impact remain relevant due to the fact that 8% of families surveyed WiFi router is located at a distance of 1 m from the child's bed.
