This article discusses the problem of registration (including biological detection) and protection from microwave electromagnetic radiation. To consider the method of integral biological and instrumental recording of the intensity of microwave electromagnetic radiation and to evaluate the method of protection using a passive multifrequency re-emitter generator with a radio holographic antenna (trade mark EQVILUM). A series of experiments were carried out to determine the number of double-strand breaks in DNA (DS DNA) by the foci of γH2AX repair proteins, to assess proliferative activity and clonogenic ability after 3 hours of exposure to microwave electromagnetic radiation with a frequency radiation of 1200 MHz both with shielding and without it on a culture of human lung fibroblasts (MRC5 line). It is shown that no changes in the level of DS DNA were revealed in experimental cells, however, a decrease in the clonogenic ability of irradiated cells without shielding was observed against the background of their high proliferative activity. The mechanisms of the observed cellular effects formation are unclear and we suppose that they can be associated with both a change in the metabolism of irradiated cells and with the triggering of certain intracellular mechanisms initiated by electromagnetic radiation (EMR). This study made it possible to identify effective ways of integral assessment of the biological effects of microwave electromagnetic radiation as well as ways of protection against it. A film microcircuit – an autonomous module of a passive multi-frequency re-emitter generator with a radio holographic antenna (EQVILUM trademark) has shown its high efficiency in protection against man-made microwave electromagnetic radiation and can be recommended as an additional means of effective protection.","PeriodicalId":169108,"journal":{"name":"Biomedical Radioelectronics","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132583078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study has no analogues neither in Russian nor in foreign publications and is currently exclusive. Objective – to determine the patterns of manifestation of contra- and ipsilateral effects, using individual changes in indicators of a simple auditory-motor response obtained as a result of longitudinal observations. The analysis of changes in the parameters of a simple auditory-motor reaction was carried out during mono-presentation of a sound signal on the left and on the right in 145 children and adolescents aged 7-14 years (470 measurements), who were under observation for 2 or more years, depending on changes in the mode of use mobile phone. Further, 48 cases were excluded (change in the lateralization of use, for example, the respondent brought the phone to both the right and the left ear, “changed” the leading ear, etc.). Three variants of changes in the mode of using MP in the longitude period (gradient of time change) were established: an increase in time (the group \"less–more\"), a decrease in time (group \"more–less\") and no changes. For each group, 4 variants of changes in the parameters of SAMR were revealed in the dynamics of observations along the longitude: decrease in SAMR indicators on the left (left ear) and increase in the right (right ear); decrease in indicators on the left and increase on the right and synchronous decrease or increase in indicators on the right and left. An assessment of the strength of the correlation was carried out (a linear Pearson correlation coefficient was used and an assessment of the statistical significance was carried out): between changes in the gradient of changes in the time of MP usage and SAMR, as well as changes in the lateralization of effects (changes in the frequency of occurrence of ipsi- and contralateral effects). The multivariance of changes in SAMR indicators and lateralization of effects was revealed depending on the mode of MP use. The proposed approach to the analysis of changes in a simple auditory-motor reaction and daily time of using a mobile phone makes it possible to suggest some mechanisms of changes in the parameters of the auditory analyzer in response to the duration of exposure to electromagnetic radiation from a mobile phone. The presence of contralateral effects of changes in SAMR parameters can serve as an assessment of the “capture” of the brain structures of children and adolescents by MP electromagnetic radiation. The results obtained once again prove the level of negative impact on the auditory system of children and adolescents.
