The Impact

В работе рассматривается метод синтеза математических моделей прогнозирования и диагностики заболеваний, провоцируемых воздействием электромагнитных полей радиочастотного диапазона, позволяющий контролировать текущее состояние человека с целью дальнейшего принятия решений о возможной коррекции функций организма в случае необходимости. С учетом неполного и нечеткого описания исследуемого класса заболеваний в качестве базового математического аппарата выбраны технология мягких вычислений и, в частности, методология синтеза гибридных нечетких решающих правил, хорошо зарекомендовавшая себя при решении задач с аналогичной структурой данных и типом неопределенности. Предлагаемый метод синтеза позволяет учитывать мультипликативный эффект воздействия на организм человека электромагнитных полей (ЭМП) различной модальности и интенсивности с учетом других эндогенных и экзогенных факторов риска. С учетом того, что для достаточно мощных ЭМП радиочастного диапазона определены предельно допустимые уровни с известными последствиями, а для низкоинтенсивных ЭМП указаны лишь тенденции возможных заболеваний в основном на качественном уровне, предлагаются две различные ветви синтеза соответствующих решающих правил. Для мощных и стабильных ЭМП предлагается использовать модификацию известных моделей, полученных для промышленных энергосетей. Для оценки влияния низкоинтенсивных, нестабильных ЭМП радиочастотного диапазона на организм человека предлагается использовать нечеткие табличные модели и ряд чувствительных к действию ЭМП радиочастотного диапазона индикаторов. К таким индикаторам относятся состояние внимания, памяти, мышления, а также динамика изменения энергетического состояния биологически активных точек (БАТ), связанных с исследуемой патологией, и общесистемных БАТ Taking into account the incomplete and fuzzy description of the studied class of diseases, the basic mathematical apparatus was chosen as a soft computing technology, and, in particular, the methodology for the synthesis of hybrid fuzzy solving rules, which has proven itself well in solving problems with a similar data structure and type of uncertainty. The proposed synthesis method allows us to take into account the multiplicative effect of electromagnetic fields (EMF) of different modality and intensity on the human body, taking into account other endogenous and exogenous risk factors. Taking into account that the maximum permissible levels with known consequences are defined for sufficiently powerful EMF of the radio frequency range, and only trends of possible diseases are indicated for low-intensity EMF, two different branches of synthesis of the corresponding decisive rules are proposed at the qualitative level. For powerful and stable EMF, it is proposed to use a modification of known models obtained for industrial power grids. To assess the impact of low-intensity, unstable RF EMF on the human body, it is proposed to use fuzzy tabular models and a number of indicators sensitive to the action of RF EMF. These indicators include the state of attention, memory, thinking, as well as the dynamics of changes in the energy state of biologically active points (BAP) associated with the studied pathology and system-wide BAP

Significant Intensity

Numerous studies of domestic and foreign researchers show that long-term exposure to electromagnetic fields (EMF) of artificial radio frequency range have negative effects on the human body. At the same time, if the effects of EMF of significant intensity are sufficiently well studied and regulated by the relevant sanitary norms and rules and state Standards, the harmful effects of low-intensity EMF are confirmed by many researchers, but there are practically no quantitative estimates of their impact on human health in combination with other exogenous and endogenous factors. In real conditions, the human body is often exposed to combined, combined and mixed EMF effects of various frequency ranges of different intensity, which cause a multiplicative effect, leading to an increased risk of occurrence and development of a number of socially significant diseases, especially when they are long-term exposure

Harmful Effects

In recent years, there has been a massive distribution of mobile phones and Wi-Fi networks. In this regard, concerns about their potential effects on living organisms, including humans, are increasing. Despite earlier assumptions about the absence of harmful effects of short-term exposure to radio frequency electromagnetic fields emitted by mobile phones and Wi-Fi networks, there is now increasing evidence of the potentially harmful effects of electromagnetic fields on the human body through the induction of oxidative stress and damage to DNA structure. It is assumed that prolonged exposure to electromagnetic fields can cause the development of various pathological conditions in the human body, including oncological diseases, impaired cognitive functions and sleep, etc. This review analyzes and summarizes existing studies indicating various negative effects of radio frequency electromagnetic fields on human and animal cells. Since there is a large amount of conflicting data on the effect of electromagnetic fields on the human body, only further research can provide an answer to the possible negative effects of mobile phones and Wi-Fi networks usage.

Different Levels

Despite the fact that there are still conflicting opinions about the damage caused by modern wireless communication technologies, most scientists report on the negative biological effects of low-intensity radio frequency electromagnetic radiation at different levels of the organization of live nature. There is no doubt that there is a need not only for a sanitary and hygienic assessment of man-made electromagnetic effects on humans, but also for an environmental assessment for biota. The purpose of the study was to assess the potential environmental risk of electromagnetic impact in the centimeter range on natural ecosystems. The initial data were the authors' own results in the field of radiobiology of non-ionizing radiation, as well as published of other researchers. The article analyzes the biological effects of radio frequency electromagnetic fields detected in organisms of different systematic groups and levels of organization. The data on the non-thermal biological effects of electromagnetic fields indicate a high sensitivity of different species to this factor. The analyzed research results emphasize the need to take into account the features of non-thermal effects of electromagnetic radiation on biota, since these radiations can have a negative impact on different hierarchical levels in natural ecosystems.
