[On one term (translation of SAR) in the dosimetry of radiofrequency electromagnetic fields].

Uncertainties in the use of some terms in the dosimetry of radiofrequency electromagnetic fields are discussed. We have come to the conclusion that the term conventionally applied in the Russian literature to describe the absorbed energy is an incorrect translation of the international term "Specific Absorption Rate" (SAR). The main error in the Russian term is that the energy rather than the rate is absorbed. More precise Russian definition for this term is suggested by analogy with the dosimetry of ionizing radiation. In this case, the dimension of this parameter remains without any change.

[Mobile communication and health of population: estimation of danger, social and ethical problems].

Population lives under new electromagnetic conditions: constant round-the-clock compulsory chronic exposure of all groups of population to modulated wide spectrum of EMF RF during the work of base stations of mobile communication; daily and lifelong (from childhood) exposure of the brain to EMF RF of the mobile phone. Effects of exposure to EMF RF of low levels are presented. Results of research into chronic EMF RF exposure are absent. International recommendations and domestic guidelines do not take into account the changing conditions of EMF RF influence on the population: the brain has become a critical body, and children have been included in the risk group. Population actively continues to use mobile communication. In this situation estimation of the risks from mobile communication has become a social and ethical problem.

[Autoimmune processes after long-term low-level exposure to electromagnetic fields (the results of an experiment). Part 1. Mobile communications and changes in electromagnetic conditions for the population. Needs for additional substantiation of the existing hygienic standards].

Mobile communications provides a new source of electromagnetic exposure for almost the whole population of the Russian Federation. For the first time in the history of civilization the brain of mobile phone users was exposed to localized radiofrequency (RF) electromagnetic fields (EMF). Population exposure from the base stations is also considered to be specific. However, existing standards for limiting the exposure do not account for this special EMF source and may not ensure the absence of health effects. There was a need for reliable information that would extend databases used for development of new standards. As recommended by the World Health Organization an additional experiment was performed under the supervision of foreign experts, which showed changes in autoimmune status in rats after long-term low-level RF EMF exposure with an incident power density of 500 microW/cm2.

[Autoimmune processes after long-term low-level exposure to electromagnetic fields (the results of an experiment). Part 2. General scheme and conditions of the experiment. Development of RF exposure conditions complying with experimental tasks. Animal's status during the long-term exposure].

This paper describes the conditions for handling and exposure of experimental animals (Wistar rats) and methods used in the study of immunological effects of long-term low-level (500 microW/cm2) exposure to radiofrequency (2450 MHz) electromagnetic fields, performed under auspices of the World Health Organization.

[Autoimmune processes after long-term low-level exposure to electromagnetic fields (the results of an experiment). Part 4. Manifestation of oxidative intracellular stress-reaction after long-term non-thermal EMF exposure of rats].

This paper presents the results of the study of the effects of long-term low-level exposure of rats to microwaves. Rats were exposed in far field to 2450 MHz continuous wave fields providing an incident power density at the cages of 500 microW/cm2 for 7 hours daily for a total of 30 days resulting in a whole-body SAR of 0.16 +/- 0.04 W/kg. Three groups ("EMF-exposure", "sham-exposure" and cage-control) were formed, each consisting of 16 rats. Circulating antibodies (IgA, IgG and IgM) directed against 16 chemical substances were evaluated in coded serum from each group of rats by enzyme multiplied analysis (ELISA test). An increased amount of compounds resulting from interaction of amino acids with nitric oxide (NO) or its derivatives (NO2-Tyrosine, NO-Arginine, NO-Cysteine + NO-Bovine Serum Albumin, NJ-Methionine + NO-Asparagine + No-Histidine, NO-BTrypnohan + NJ-Tyrosin), fatty acids with small chains, hydroxylated fatty acids, palmitic/myristic/oleic acid, AZE (product of oxidation of fatty acids) was found in blood serum from EMF-exposed rats. As a rule, antibodies to conjugated antigens were seen for IgM, rarely seen for IgG and were completely absent for IgA. The levels of antibodies were higher on day 7 after the exposure compared to those on day 14 after the exposure.

[Autoimmune processes after long-term low-level exposure to electromagnetic fields (the results of an experiment). Part 5. Impact of the blood serum from rats exposed to low-level electromagnetic fields on pregnancy, foetus and offspring development of intact female rats].

This study evaluated possible adverse effects of injection of blood serum from rats exposed to microwaves at a power density of 500 microW/cm2 on pregnancy and foetal and offspring development in intact female rats. The study was performed with 59 pregnant Wistar rats. In utero mortality, embryo and foetal body weights and placenta weight were used for the evaluation of embryo and foetal development. Generally accepted integral and specific parameters were used for the evaluation of postnatal development of offspring during the first 30 days of life. It was shown that intra peritoneal injection of blood serum from IMF exposed rats (chronic 30-day RF exposure at 500 microW/cm2) to intact rats on the 10th day of pregnancy resulted in adverse effects on foetal and offspring development. Total mortality (in utero + postnatal) as well as delay in offspring development was higher in this group.

[Autoimmune processes after long-term low-level exposure to electromagnetic fields (the results of an experiment). Part 3. The effect of the long-term non-thermal RF EMF exposure on complement-fixation antibodies against homologenous tissue].

This paper presents the results of the study of immunological effects of long-term low-level exposure of rats to microwaves. Rats were exposed in the far field to 2450 MHz continuous wave fields providing an incident power density at the cages of 500 microW/cm2 for 7 hours daily for a total of 30 days, resulting in a whole-body SAR of 0.16 +/- 0.04 W/kg. Effects of the exposure on immunological parameters in the brain and liver of rats were studied using Complement Fixation Test at low temperature (4 degrees C). Three groups ("EMF-exposure", "sham-exposure" and cage-control) were formed, each consisting of 16 rats. On the 14th day after the 30-day exposure, titers of antibodies against brain tissue were 0.69 +/- 0.08 in the cage-control group, 0.89 +/- 0.05 in the sham-exposed group and 1.19 +/- 0.07 in the EMF-exposed group. The appearance of antibodies against liver antigens was less. The increase in titres of antibodies against brain homogenates in the sham-exposed and EMF-exposed groups could be explained by the stress-reaction of the animals and autoimmunization of organism.

[Dependence of the non-thermal radiofrequency electromagnetic field bioeffects on the typological features of electroencephalogram in humans].

In researches with participation of volunteers bioeffects of short-term non-thermal radiofrequency electromagnetic field (RF EMF) exposure were studied. The basic form of brain's reaction was the amplification of energy in a-range in electroencephalogram (EEG) spectra. Dependence of these changes, not only due to the changes of the exposure parameters, but also due to personal EEG typological features was shown. Moderate degree of the alpha frequencies domination in the background promoted development of reaction of a brain to the RF EMF exposure. To a lesser degree it was shown at hyperactivity of this range and, practically, was absent in the conditions of theta- or beta2-range domination in the EEG background with the open and closed eyes. The combination of RF EMF exposure and monotonous activity has authentically strengthened result, keeping the basic form of reaction (energy amplification in the alpha range of EEG spectrum) and dependence on EEG typological features.

[Anthropogenic EMF effects on the condition and function of natural ecosystems]. / Vozdeistvie antropogennogo élektromagnitnogo polia na sostoianie i funktsionirovanie prirodnykh ékosistem.

A review of Russian and foreign studies of EMF effects on living environment was made. Vast range of EMF frequencies and intensities affect on functions and condition of ecosystems. Even non-thermal EMF levels could cause reversible changes in physiological process regulation. Some changes were observed in animal behavior such as motive activity, spatial orientation, reduction of ability to form a conditioned response. Some animal species (some insects, birds, reptiles) use electromagnetic fields for spatial orientation during migration. Biological communities are very sensitive to EMF effects and could become the biological indicators of electromagnetic pollution.
