According to the authors there is no evidence of a causal association between wireless phone use and brain tumours. Because of likely biases a small increased risk cannot be ruled out.

Abstract

We systematically reviewed the existing literature on the safety of the use of smartphone, mobile phone/Internet, and Wi-Fi by people with epilepsy (PWE), according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Scopus, MEDLINE, and Google Scholar from the inception to April 9, 2021 were searched. These key words were used “epilepsy” OR “seizure” AND “Mobile Phone” OR “Cell Phone” OR “Smartphone” OR “Wi-Fi” OR “Electromagnetic” OR “Radiation.” The primary search yielded 7766 studies; 33 studies were related. In total, 19 manuscripts were based on animal/computational studies and 14 articles reported human investigations. Among animal studies, 10 articles suggested detrimental effects by electromagnetic fields (EMFs) on brain function/seizure activity, while nine studies negated this hypothesis. Among human studies, seven studies suggested detrimental effects by EMFs on brain function/seizure activity, while seven studies negated this hypothesis. None of the studies provided a good level of evidence. In one human study, all seven patients with epilepsy and abnormal EEG during the sham exposure, had an increase in the number of epileptic events with exposure to mobile phone radiation. In another study of the detrimental effects of smart technology device overuse among school students, an association was found between reporting seizures and the hours of smart technology device use. While high-quality evidence on the safety of the use of smartphone, mobile phone/Internet, and Wi-Fi in PWE is lacking, prudent use of these technologies, including using wired hand-free sets or other exposure-reducing measures is recommended.

Abstract

The continuously increasing usage of cell phones has raised concerns about the adverse effects of microwave radiation (MWR) emitted by cell phones on health. Several in vitro and in vivo studies have claimed that MWR may cause various kinds of damage in tissues. The aim of this study is to examine the possible effects of exposure to low-intensity MWR on DNA and oxidative damage in the livers of rats. Eighteen Sprague-Dawley male rats were divided into three equal groups randomly (n = 6). Group 1 (Sham-control): rats were kept under conditions the same as those of other groups, except for MWR exposure. Group 2: rats exposed to 1800 MHz (SAR: 0.62 W/kg) at 0.127 ± 0.04 mW/cm² power density, and Group 3: rats exposed to 2,100 MHz (SAR: 0.2 W/kg) at 0.038 ± 0.03 mW/cm² power density. Microwave application groups were exposed to MWR 2 h/day for 7 months. At the end of the exposure period, the rats were sacrificed and DNA damage, malondialdehyde (MDA), 8-hydroxydeoxyguanosine (8-OHdG), and total oxidant-antioxidant parameter analyses were conducted in their liver tissue samples. It was found that 1800 and 2100 MHz low-intensity MWR caused a significant increase in MDA, 8-OHdG, total oxidant status, oxidative stress index, and comet assay tail intensity (P < 0.05), while total antioxidant status levels (P < 0.05) decreased. The results of our study showed that whole-body exposure to 1800 and 2100 MHz low-intensity MWR emitted by cell phones can induce oxidative stress by altering oxidant-antioxidant parameters and lead to DNA strand breaks and oxidative DNA damage in the liver of rats.

Abstract

Exponential increase in mobile phone uses, given rise to public concern regarding the alleged deleterious health hazards as a consequence of prolonged exposure. In 2018, the U.S. National toxicology program reported, two year toxicological studies for potential health hazards from exposure to cell phone radiations. Epigenetic modulations play a critical regulatory role in many cellular functions and pathological conditions. In this study, we assessed the dose-dependent and frequency-dependent epigenetic modulation (DNA and Histone methylation) in the hippocampus of Wistar rats. A Total of 96 male Wistar rats were segregated into 12 groups exposed to 900 MHz, 1800 MHz and 2450 MHz RF-MW at a specific absorption rate (SAR) of 5.84 × 10^-4 W/kg, 5.94 × 10^-4 W/kg and 6.4 × 10^-4 W/kg respectively for 2 h per day for 1-month, 3-month and 6-month periods. At the end of the exposure duration, animals were sacrificed to collect the hippocampus. Global hippocampal DNA methylation and histone methylation were estimated by ELISA. However, DNA methylating enzymes, DNA methyltransferase1 (DNMT1) and histone methylating enzymes euchromatic histone methylthransferase1 (EHMT1) expression was evaluated by real-time PCR, as well as further validated with Western blot. Alteration in epigenetic modulation was observed in the hippocampus. Global DNA methylation was decreased and histone methylation was increased in the hippocampus. We observed that microwave exposure led to significant epigenetic modulations in the hippocampus with increasing frequency and duration of exposure. Microwave exposure with increasing frequency and exposure duration brings significant (p < 0.05) epigenetic modulations which alters gene expression in the hippocampus.

Abstract

The use of mobile phones is based on radiofrequency (RF) waves, and the devices act as transmitters and receivers of non-ionizing energy. The micronucleus test was developed to identify increases in the occurrence of mutations in cells exposed to various agents. This systematic review with meta-analysis adhered to the following protocol: defining the objective, outlining the search method (PICO model), conducting the search, identifying literature, selecting articles, and extracting data. The study aimed to answer the following research question: Does non-ionizing radiation emitted by mobile phones have genotoxic and/or cytotoxic effects on the oral epithelium? The search for evidence published 2009-2019 was conducted in the MEDLINE, PubMed, Scopus, LILACS, Google Scholar, PROSPERO, and Cochrane Library databases. The following inclusion criteria were defined: investigations of effects on the oral mucosa related to RF; investigations of cytotoxic and/or genotoxic effects; investigations involving humans; and investigations using cells exfoliated from the oral epithelium. Investigations related to the parotid gland were excluded. The search strategy found 464 articles; after application of the eligibility criteria, 358 abstracts were analyzed and 351 abstracts excluded. After 7 full texts were reviewed, 1 study was excluded. The 6 included studies were classified as level 5 quality of evidence (observational studies). The meta-analysis included 2 studies that compared the frequency of micronuclei on the side exposed to RF electromagnetic fields (RF-EMFs) to that on the unexposed side. The studies evaluated presented a low degree of evidence, but the meta- analysis indicated that no genotoxic effects are associated with mobile phone use. However, observations of other nuclear abnormalities in some studies suggest the occurrence of cytotoxic effects caused by exposure to the RF-EMFs emitted by mobile phones. More studies are necessary to prove or refute this association.

Abstract

The radiofrequency electromagnetic fields (RF-EMFs) produced by widely used mobile phones are classified as possibly carcinogenic to humans by International Agency for Research on Cancer (IARC). Current data on the relationship between exposure to RF-EMFs generated by commercial mobile phones and brain cancer are controversial. Our studies show that this controversy may be caused by several parameters. However, it seems that the magnitude of exposure to RF-EMFs plays a basic role in RF-induced carcinogenesis. There is some evidence indicating that, in a similar pattern with ionizing radiation, the carcinogenesis of non-ionizing RF-EMF may have a nonlinear dose-response relationship. In this paper, the evidence which supports a nonlinear J-shaped dose-response relationship is discussed.

The monograph “Mobile phone and health” has been published, author Yuri Borisovich Zubarev, corresponding member of the Russian Academy of Sciences, Doctor of Technical Sciences, member of the RNKZNI

Monograph by Corresponding Member of RAS Yu.B. Zubarev is a special edition because of the author’s unique scientific and practical experience, which allows him to comprehensively consider the topic. Yuri Borisovich is well known to specialists in the field of radiobiology and hygiene of non-ionizing radiation, since it was he who ordered the sanitary standards for radio frequencies that were published in 1984 and 2003. It is these SanPiNs that today determine approaches to the electromagnetic safety of cellular communications and other radio transmission facilities.

But, first of all, Corresponding Member of the Russian Academy of Sciences Yu.B. Zubarev is known in the telecommunications industry – as the deputy minister of communications in charge of science in the industry, and as the director of the Radio Research Institute. He stood at the origins of the creation of federal mobile communication systems for general and special purposes, for which he was awarded the high award of the Government of the Russian Federation.

The monograph analyzes the application of the electromagnetic field in radio communications, in particular in mobile communications. The author examines the history of the development of sanitary standards for radio frequencies in our country, analyzing the issue from the point of view of the state customer of these SanPiN. Yuri Borisovich notes an important feature of the procedure for developing the maximum permissible levels of radio frequencies – under his leadership, the creation of sanitary standards preceded the development of fundamentally new radio transmitting means or went in parallel with the creation of new technology. The State Program for the Study of the Bioeffects of Radio Frequencies, adopted in 1984, made it possible to conduct biomedical research with promising modulation methods and a method for organizing complex electromagnetic signals, which provided a scientific groundwork that is relevant even for analyzing the biological effects of a 5G signal.

A significant section of the book is devoted to the prospects for the development of mobile communications. The opinion of Yuri Borisovich, as the ideologist of the scientific and technical foundations of this popular technology, is extremely important for understanding the possible consequences of electromagnetic pollution for the health of the population of our country, and also allows you to analyze and choose the optimal measures to create a healthy environment. Special attention of Yu.B. Zubarev pays attention to methods of protecting children and pregnant women, believing that their health is a task of state importance in the Russian Federation.

The monograph was reviewed by the founding member of the RNKZNI, Doctor of Medical Sciences, Professor Yu.P. Paltsev and Doctor of Technical Sciences E.P. Arzumyan, Chief Researcher, MNITI CJSC.

Abstract

Background: Prenatal adverse effects of radiofrequency electromagnetic fields (RF-EMF) exposure on nervous system are an issue of major concern.

Objective: Thus, in this study we evaluated the membrane current flow properties of Purkinje neurons after maternal exposure to 900 MHz pulsed RF-EMF.

Material and methods: In this experimental study, during all days of pregnancy, rats in the EMF-exposed group were exposed to 900 MHz pulsed-EMF radiation for 6 h per day. The effects of RF-EMF exposure on the electrophysiological properties of the Purkinje cerebellum neurons from male pups were evaluated by whole-cell patch clamp recordings in current and voltage clamp modes. In voltage-clamp experiments, the holding potential was -60mV, and a depolarizing voltage step (1000 ms duration) was applied from -60 to +50 mV in 10 mV increments at 2s intervals.

Results: The exposure group demonstrated reduced spontaneous firing associated with upward and rightward shift in I/V curve compared to the control rats. Moreover, the peak amplitude of the current for the exposure pups also revealed a significant decrement. The reversal potential was +40 mV and +20 mV for the control and RF-EMF groups, respectively and showed significant differences between the two groups.

Conclusion: The decrease in ion’s conductance could be attributed to the observed decrease in the voltage onset of the inward current, peak amplitude and voltage shift.

In 2015, the city of Berkeley passed an ordinance requiring cell phone retailers to advise consumers, in a flyer at the point of sale, that keeping a cell phone in their pocket or near their body could expose them to wireless radiation above Federal Communications Commission safety levels. Councilmembers understood that manufacturers deceptively hide this federally mandated information deep within user manuals or in the phone that few ever see. The council also understood that cell phones are allowed to be tested for compliance away from the body— not as used.

A survey of Berkeley residents found overwhelming support for Berkeley’s ordinance. Eight-five percent of residents never saw recommendations from manufacturers about how to best protect against overexposure to cell phone radiation and 82% want this information at the point of sale.

America’s trade association representing the wireless communications industry (CTIA) challenged this ordinance all the way to the United States Supreme Court twice and lost every step of the way. Now this well-funded industry, along with support from the FCC, is again fighting to prevent the public from simple truthful information. Despite losing, the industry has now asked a federal court in California to rehear the case. Industry is repeating its failed argument that the FCC claims cell phones are safe no matter how used. A federal district court hearing is set in San Francisco for Thursday, July 23, on this motion.
