Декларируемое увеличение пространственной плотности излучающих периферийных (пользовательских, оконечных и т. п.) устройств (ПУ) мобильной связи до 0,1 ПУ/м2 в сетях 4G (LTE), до 1,0 ПУ/м2 в сетях 5G (NR) и до 10 ПУ/м2 в перспективных сетях 6G может быть причиной недопустимого роста электромагнитного фона и соответствующих вынужденных рисков для здоровья населения. Предложена методика оценки вклада излучений этих устройств в уровень антропогенного электромагнитного фона, создаваемого системами мобильной (сотовой) связи. Методика основана на анализе электромагнитной нагрузки на территорию, создаваемой стационарными и подвижными источниками излучения систем мобильной связи и определяемой территориальной плотностью мобильного трафика, его асимметрией в нисходящей и восходящей передаче данных, степенью концентрации ПУ в окрестности точки наблюдения, спектральной эффективностью радиоканалов мобильной связи, размерами зоны обслуживания базовых станций и рядом других характеристик. Приведены расчетные данные, свидетельствующие о том, что в местах концентрации излучающих ПУ образуемая ими составляющая электромагнитного фона может оказаться преобладающей, многократно превышая вклад излучений базовых станций и определяя фактический уровень вынужденных рисков для здоровья населения, что требует учета в системе их гигиенического нормирования.

The declared increase in spatial density of user (terminal, peripheral, etc.) radiating equipment (UE) of mobile communications up to 0.1 UE/m2 in 4G (LTE) networks, up to 1.0 UE/m2 in 5G (NR) networks and up to 10 UE/m2 in promising 6G networks may cause an unacceptable increase in electromagnetic background and in corresponding forced risks to public health. The paper proposes a method for assessing the contribution of UE radiations to the level of anthropogenic electromagnetic background created by mobile communications. This method is based on the analysis of the electromagnetic loading on the area created by stationary and mobile radiation sources of mobile communications and determined by the area density of mobile traffic, its asymmetry in downlink and uplink data transmission, the degree of UE concentration in the observation point vicinity, the radio channels spectral efficiency, the size of base stations service areas and other characteristics. The calculated data are given, indicating that in places of UE concentration, the component of electromagnetic background formed by UE radiations may be predominant, many times exceeding the contribution of base station radiations, and determining the actual level of forced risks to public health, which requires consideration in the system of their hygienic rationing.
