Electricity substations take electricity from power lines and transformer lines to transform it from high to low voltage and distribute to the consumers. These substations generate low frequency electromagnetic fields similar to those emitted from over head power lines and electrical appliances at home. The present study is focused on assessing the potential bioeffects of Extremely Low Frequency Electromagnetic Fields (ELF-EMFs) on melatonin level and oxidative stress biomarkers, in subjects occupationally exposed to 132 kV high voltage substation in Hyderabad, India. These subjects are involved in maintenance and installation of power line distribution at electricity transmission network. The ELFEMFs exposed subjects (n = 142) included the electric utility workers, who were compared with age, and socioeconomic status matched controls (n = 151). The subjects were professionally categorized based on their job titles, with different exposure levels, as administrative workers (low exposure),
Workplace exposure to very low frequency electromagnetic fields may be linked to a doubling in risk of developing the most common form of motor neurone disease -- amyotrophic lateral sclerosis, or ALS for short -- suggests research published online in Occupational & Environmental Medicine.
All organisms are probably exposed to different types of electromagnetic fields (EMFs). This study is an attempt to evaluate the effect of extremely low-frequency EMFs (50 Hz) on some growth parameters and survival rate of common carp fingerling. The fry (n = 120, averaged 16.76 ± 0.88 g in initial weight) was exposed to ELF-EMF at four intensities of 0.1, 0.5, 1 and 2 mT only once for 2 h and then reared for 60 days. The obtained results revealed that all growth indices were significantly (p | 0.05) improved by increasing in the EMFs intensity. 2 mT treatment indicated the highest final weight (43.95 ± 0.27 g), weight gain (6.83 ± 0.10 g), weight gain rate (20.94 ± 0.13 %), daily growth rate (0.38 ± 0.00 g day-1), specific growth rate (1.26 ± 0.01 % day-1) and the lowest food conversion ratio (p | 0.05). Survival rate had significantly (p | 0.05) increased in all exposed treatments compared to the control group. In conclusion, ELF-EMF can enhance the growth indices and survival rate of common

Radiofrequency electromagnetic fields are absorbed by the body and may subsequently provoke various effects. The strength of the energy absorption depends on the strength and the frequency of the electromagnetic fields, but also on the properties and structures of the biological tissue. Forces and heating due to radiofrequency electromagnetic fields are clearly proven and physically defined.

Loomis DP, Savitz DA, Ananth CV.. Department of Epidemiology, University of North Carolina School of Public Health, Chapel Hill 27599-7400.. BACKGROUND: Previous epidemiologic studies have suggested that exposure to electric or magnetic fields in occupational and residential environments may cause cancer. Recent experimental findings provide some support for the hypothesis that exposure to extremely low-frequency electromagnetic fields reduces the pineal glands nocturnal production of the hormone melatonin, thereby increasing susceptibility to sex hormone-related cancers such as breast cancer.. PURPOSE: Our purpose was to assess the evidence that cancer of the female breast might be associated with exposure to extremely low-frequency electromagnetic fields.. METHODS: Records of women who had breast cancer as the underlying cause of their death (ICD-9 174) and control subjects (four per case) were selected from computer files of U.S. mortality data for the years 1985-1989. Women 20 years and ...

Exposure assessment is the determination or estimate of the magnitude, frequency of occurrence, and rate of exposure of an individual or a group to an environmental agent. The agents of interest in this case are the electric and magnetic fields (EMF) in the extreme low-frequency range that includes the power frequency of 50/60 Hz. There are an increasing concern that exposure to EMF may be associated with biological and health effects. This concern has prompted numerous measurement projects and the development of instrumentation, methodologies, and exposure models and simulations. This paper identifies the status of EMF exposure assessment research related to occupational exposures. It draws the recent results to emphasize the unique aspects of EMF exposures in the home and utilities environments, and highlights the research needs. The intensities of electromagnetic fields have been measured under power transmission and distribution lines, at substations and industrial plants and near various ...

The use of electromagnetic field in the treatment of diseases has already been known for centuries. Low hazard, wide applicability, good clinical effect and the relatively low cost enable the electromagnetic field therapy to be widely used. The biological effect of the electromagnetic field is based on inter alia, analgesic, anti-inflammatory, osteogenetic and regenerative actions, which are associated with the changes in cellular signal transmission, action on biological membranes, ion transport processes, protein synthesis, cell proliferation and apoptosis. In addition, the electromagnetic field increases quantity of collagen content elevating its density and a more regular arrangement. Furthermore, it induces the activation of glutathione peroxidase and intensification of the process of erythropoiesis leading to better use of oxygen in the tissues around the wound. The electromagnetic field is used in rehabilitation of patients with diseases of skeletal, nervous and respiratory systems. ...
Several studies have shown that low frequency electromagnetic field has biological and therapeutic potential on the human body, however, to very limited extent on the heart. In the current study cardiac patients suffering from exercise-induced-angina will undergo two consecutive stress tests, one test after being exposed for 30 minutes to the magnetic field and the other test after being exposed to placebo (magnetic field not operated). The order of which the magnet will be operated will be randomly assigned for the patients so a group of patients will be exposed to the magnetic field at their first stress test and another groups of patients will be exposed to the magnetic field at their second stress test. During resting period, and while the patients are subjected to the magnetic field, a 12 lead electrocardiogram (ECG) will be monitored. Thereafter the magnetic field and frequency will be turned off and the patients will be subjected to graded exercise stress test during which they will be ...
Purpose : A great deal of evidence has confirmed that electromagnetic fields can affect the central nervous system and are effective in gene expression as well as development, differentiation, cell proliferation, and apoptosis of embryonic neural cells.

Young adult long-term study: Beneficial cognitive effects of chronic EMF exposure were observed in both Tg and NT mice. EMF exposure had essentially no effect on oxidative markers in the hippocampus of Tg mice, and the changes in oxidative markers in NT mice can be interpreted as a decrease in oxidative stress. No effect of EMF exposure on any oxidative markers was observed in the cerebral cortex tissue of either NT or Tg mice. An increase in levels of soluble Aβ in both hippocampus and frontal cortex was detected in EMF-exposed Tg mice. Aged adult long-term study:No effect of EMF exposure on cognitive performance of cognitively impaired Tg mice was observed during the initial 5 months of EMF exposure, while NT mice showed improved performance on cognitive testing 5 months after exposure initiation. After 8 months of EMF exposure the cognitive performance of EMF-exposed Tg mice was considerably better. Exposed NT mice continued to show better cognitive performance compared to the control NT ...

A novel exposure system for double-blind human electromagnetic provocation studies has been developed that satisfies the precision, control of fields and potential artifacts, and provides the flexibility to investigate the response of hypotheses-driven electromagnetic field exposure schemes on brain function, ranging from extremely low frequency (ELF) to radio frequency (RF) fields. The system can provide the same exposure of the lateral cerebral cortex at two different RF frequencies (900 and 2140 MHz) but with different exposure levels at subcortical structures, and also allows uniform ELF magnetic field exposure of the brain. The RF modulation and ELF signal are obtained by a freely programmable arbitrary signal generator allowing a wide range of worst-case exposure scenarios to be simulated, including those caused by wireless devices. The maximum achievable RF exposure is larger than 60 W/kg peak spatial specific absorption rate averaged over 10 g of tissue. The maximum ELF magnetic field ...
Microwave and other low frequency electromagnetic fields (EMFs) have been shown to act by activating voltage-gated calcium channels (VGCCs) with most biological effects being due to elevated intracellular calcium, consequent nitric oxide (NO) elevation and either peroxynitrite or NO signaling. This, the role of excessive intracellular calcium in microwave effects, the greater biological effects of pulsed fields and some 20,000 papers on microwave biological effects show that the current international safety standards do not predict biological hazard. Such standards are based on the false assumption that the predominant effects of microwave and other low frequency EMF exposures are due to heating. A whole series of biological changes reportedly produced by microwave exposures can now be explained in terms of this new paradigm of EMF action via VGCC activation, including: oxidative stress; single and double stranded breaks in cellular DNA; therapeutic effects; blood-brain barrier breakdown; ...

Physiological effects have been observed in a human subject in response to stimulation of the skin with weak electromagnetic fields that are pulsed with certain frequencies near 1/2 Hz or 2.4 Hz, such as to excite a sensory resonance. Many computer monitors and TV tubes, when displaying pulsed images, emit pulsed electromagnetic fields of sufficient amplitudes to cause such excitation. It is therefore possible to manipulate the nervous system of a subject by pulsing images displayed on a nearby computer monitor or TV set. For the latter, the image pulsing may be embedded in the program material, or it may be overlaid by modulating a video stream, either as an RF signal or as a video signal. The image displayed on a computer monitor may be pulsed effectively by a simple computer program. For certain monitors, pulsed electromagnetic fields capable of exciting sensory resonances in nearby subjects may be generated even as the displayed images are pulsed with subliminal intensity.. ...
Right-handed healthy adult subjects aged 18-60 years were recruited to participate in an fMRI study. Exclusion criteria included claustrophobia, nerve damage to the hand, analgesic use on the day of the study, alcohol use on the day of the study and the inability to lie still for an hour, as well as any other MRI exclusion criteria (e.g. cardiac pacemakers). Subjects were blinded to their condition of sham versus pulsed magnetic field exposure.. Subjects were given acute thermal pain with a Medoc TSA-II (Medoc, Israel). A 1.6 × 1.6 cm Peltier thermode probe was attached to the hypothenar region of the right-hand and heated under computer control (heat stayed on for 21 s, off for 24 s, with 3 s ramps in between). Each subject underwent a test prior to the fMRI to determine their individual pain tolerance. The target temperature was adjusted individually to attain a subjective pain rating of at least 7/10 on a verbal analogue scale (1-10). Subjects were asked to confirm that they could tolerate ...

To investigate the ability of prokaryotic microorganisms to activate strategies in adapting themselves to the environmental stress induced by exposure to extremely low frequency electromagnetic fields (ELF-EMF), cultures of Escherichia coli ATCC 700926 exposed at 50 Hz EMF (0.1, 0.5, 1.0 mT), and the respective sham-exposed controls were studied for: the total and culturable counts, the viability status, the antimicrobial susceptibility pattern, the morphological analysis, the genotypical and transcriptional profile.. Exposed samples and controls displayed similar total and culturable counts, whereas an increased cell viability was observed in exposed samples re-incubated for 24 h outside of the solenoid compared to the corresponding controls. An exposure to 50 Hz EMF of 20-120 min produced a significant change of E. coli morphotype with a presence of coccoid cells also aggregated in clusters after ...
About 50 epidemiological reports about possible associations between cancer morbidity and exposure to electromagnetic fields (EMFs) were published between 1979 and 1994. The majority of them (60‐75 per cent) documented a slight (1.5 to twofold) but significant increase in the incidence of certain rare forms of neoplasms (leukaemia, lymphoma, brain tumours). A limited support for carcinogenic potencies of EMFs is provided from cellular studies, but the effects appear to be generally weak, transient and difficult to replicate. Concludes that the available evidence associating cancer and EMF exposure is too tenuous to be convincing but too consistent to be ignored. Further progress needs better quantification of exposure levels and conditions, evaluation of dose‐effect relationships and liability to confounding carcinogenic factors that may influence morbidity rates in the investigated populations.
http://www.emfnews.org/qlinks.html. Qlink Pendant. Home Radiation Protection. Envi Headsets. Electromagnetic Field Meter. MOBILE phones are an integral part of modern telecommunications. The effect of mobile phone radiation on human health has always been a controversial subject. Now, neuroscientists from Bochum have for the first time explained the effects of high frequency electromagnetic fields (HEFs) derived from mobile phones.. They proved that extremely high-powered electromagnetic fields (EMFs) indeed influence learning processes on the synaptic level within the brain, independent from other factors like stress.. Scientists of the Department of Neuroanatomy and Molecular Brain Research (Professor Dr. med. Rolf Dermietzel) in cooperation with the Chair of. Electromagnetic Theory of the University of Wuppertal, performed the new study on rats.. For the experiment, rats were placed into differently powered non-thermal HEFs in the UMTS (Universal Mobile Communication System) operating range. ...
Due to their different physical properties, the various ranges of the electromagnetic spectrum have different effects on biological organisms. In the process, the energy of the individual photons is particularly significant. It increases constantly with increasing frequency.. Electromagnetic fields belong to "non-ionising radiation". In contrast to ionising radiation, the photons of non-ionising radiation do not have enough energy to ionise atoms and molecules, that is, to "eject" electrons from the shells and to produce positively charged particles (ions) as a result. Among other things, this means that - in contrast to X-radiation - their energy is too low to cause direct damage to genetic material and for being directly involved in the development of cancer.. However, electromagnetic fields can cause health damage in other ways:. ...
Objective: To investigate the effects of a pulsed electromagnetic field (EMF) on articular cartilage matrix biosynthesis with regard to age and cartilage damage using a matrix depleted cartilage explant model.. Methods: Cartilage explants were obtained from metacarpophalangeal joints of calves and adult cows. After depletion of the extracellular matrix by trypsin digestion, samples were maintained in serum-free basal medium with and without the addition of interleukin 1β (IL1β). Half the samples were subjected to an EMF for 24 minutes daily; the other half were left untreated. Undigested and untreated explants served as negative controls. After 7 days, biosynthesis of matrix macromolecules was assessed by [35S]sulphate incorporation and values were normalised to hydroxyproline content.. Results: The EMF increased matrix macromolecule synthesis in undigested, untreated explants (p,0.009). In matrix depleted samples the EMF had no stimulatory effect on proteoglycan biosynthesis. IL1β ...
For years, retired Maj. David Underwood has noticed that whenever he drove under power lines and around other electromagnetic fields, he would feel a buzz in what remained of his arm. When traveling by car through Texas open spaces, the buzz often became more powerful.. "When roaming on a cellphone in the car kicked in, the pain almost felt like having my arm blown off again," said Underwood, an Iraq War veteran who was injured by an improvised explosive device (IED). His injuries have resulted in 35 surgeries and the amputation of his left arm. Shrapnel from the IED also tore part of his leg and left him with more than 100 smaller wounds. "I didnt notice the power lines, cellphones on roam or other electromagnetic fields until I first felt them in my arm.". Until a recent study led by researchers at The University of Texas at Dallas was published online last month in PLOS ONE, there was no scientific evidence to back up the anecdotal stories of people, such as Underwood, who reported aberrant ...

Some water systems use minerals and/or other substances to chemically alter the waters pH values or kill bacteria. Such chemical processes are highly unstable. Chemical processes through electrolysis can also be used to ionize water introducing substances such as copper, silver, zinc and other metal alloys into water. Although many systems claims that this alkalinizes and creates various health benefits, the effect is identical to drinking lime in tap water, which leads to cellular aggregation or dehydration. Chemical-based water systems are restricted to working on water only.. During the process of activation the subtle low frequency electromagnetic field is imprinted into the water. It closely resembles the natural geomagnetic field found near healing water springs. This is a non-chemical, bio-safe process of water activation. According to Molecular Resonance Effect Thechnology developed and patented by American scientist Igor V. Smirnov, Ph.D. MRET activated water is beneficial for ...

Worldwide expansion of mobile phones and electromagnetic field (EMF) exposure has raised question of their possible biological effects on the brain and nervous system. Radiofrequency (RF) radiation might alter intracellular signaling pathways through changes in calcium (Ca(2+)) permeability across cell membranes. Changes in the expression of calcium binding proteins (CaBP) like calbindin D28-k (CB) and calretinin (CR) could indicate impaired Ca(2+)homeostasis due to EMF exposure. CB and CR expression were measured with immunohistochemistry in the hippocampus of mice after EMF exposure at 835 MHz for different exposure times and absorption rates, 1 h/day for 5 days at a specific absorption rate (SAR)=1.6 W/kg, 1 h/day for 5 days at SAR=4.0 W/kg, 5 h/day for 1 day at SAR=1.6 W/kg, 5 h/day for 1 day at SAR=4.0 W/kg, daily exposure for 1 month at SAR=1.6 W/kg. Body weights did not change significantly. CB immunoreactivity (IR) displayed moderate staining of cells in the cornu ammonis (CA) areas and ...
We aimed to review the findings of exposure assessment studies done in European countries on the exposure of the general public to low frequency electric and magnetic fields (EMFs) of various frequencies. The study shows that outdoor average extremely low frequency magnetic fields (ELF-MF) in public areas in urban environments range between 0.05 and 0.2 µT in terms of flux densities, but stronger values (of the order of a few µT) may occur directly beneath high-voltage power lines, at the walls of transformer buildings, and at the boundary fences of substations. In the indoor environment, high values have been measured close to several domestic appliances (up to the mT range), some of which are held close to the body, e.g., hair dryers, electric shavers. Common sources of exposure to intermediate frequencies (IF) include induction cookers, compact fluorescent lamps, inductive charging systems for electric cars and security or anti-theft devices. No systematic measurement surveys or personal
Introduction: To date, occupational exposure assessment of electromagnetic fields (EMF) has relied on occupation-based measurements and exposure estimates. However, misclassification due to between-worker variability remains an unsolved challenge. A source-based approach, supported by detailed subject data on determinants of exposure, may allow for a more individualized exposure assessment. Detailed information on the use of occupational sources of exposure to EMF was collected as part of the INTERPHONE-INTEROCC study. To support a source-based exposure assessment effort within this study, this work aimed to construct a measurement database for the occupational sources of EMF exposure identified, assembling available measurements from the scientific literature. Methods: First, a comprehensive literature search was performed for published and unpublished documents containing exposure measurements for the EMF sources identified, a priori as well as from answers of study subjects. Then, the ...

When we listen to government, telecom and power industry spokesmen speak about the possible health effects of exposure to electromagnetic fields, it seems they would prefer us to believe that there is no cause for concern.. Or at worst, there is controversy in the research about whether EMF exposure has any negative biological or health effects. They may cite study after study where no effect was detected. They may cite statistics about how many such negative correlation studies exist. And they may come to the conclusion that EMF exposure is safe.. Oddly, the facts they cite may be correct, but their conclusions are not.. In all examples of EMF, the energy field causes a change in everything it encounters.. EMF is a broad term which includes electric fields generated by charged particles, magnetic fields generated by charged particles in motion, and radiated fields such as TV, radio, and microwaves.. Electric fields are measured in units of volts per meter or V/m. Magnetic fields are measured in ...

Effects of electromagnetic fields (EMFs) on the incidence of breast cancer (BC) have been proposed by a number of epidemiological studies. The molecular mechanism of the impact of EMFs on cells is not yet clear, although changes in gene expression have been reported in various cellular systems. In t …
The aim of this cross-sectional study was to investigate the association between exposure to various sources of radiofrequency electromagnetic fields (RF EMFs) in the everyday environment and sleep quality, which is a common public health concern. We assessed self-reported sleep disturbances and daytime sleepiness in a random population sample of 1,375 inhabitants from the area of Basel, Switzerland. Exposure to environmental far-field RF EMFs was predicted for each individual using a prediction model that had been developed and validated previously. Self-reported cordless and mobile phone use as well as objective mobile phone operator data for the previous 6 months were also considered in the analyses. In multivariable regression models, adjusted for relevant confounders, no associations between environmental far-field RF EMF exposure and sleep disturbances or excessive daytime sleepiness were observed. The 10% most exposed participants had an estimated risk for sleep disturbances of 1.11 (95% ...
A network of low frequency electromagnetic detectors has been operating in Central Italy for more than three years, consisting of identical instruments that continuously record the electrical components of the electromagnetic field, ranging from a few Hz to tens of kHz. These signals are analyzed in real time and their power spectrum contents and time/frequency data are available online. To date, specific interest has been devoted to searching for any possible electromagnetic features which correlate with seismic activity in the same region. In this study, spectral analysis has evidenced very distinct power spectrum signatures that increased in intensity when strong seismic activity occurred near the stations of the 2009 LAquila earthquake. These signatures have revealed horizontally oriented electric fields, between 20 Hz to 400 Hz, lasting from several minutes to up to two hours. Their power intensities have been found to be about 1 μV/m. Moreover, a large number of man-made signals and meteorologic
Bioelectromagnetics (BEMs) is the study of the effect of electromagnetic fields on biological systems [1]. Though electromagnetic fields have sometimes been associated with potential for harm to the body, there are many BEM instruments and devices re-emerging in the 21st century, based on high voltage Tesla coils, that apparently bring beneficial health improvements to human organisms. The Tesla coil class of therapy devices constitute pulsed electromagnetic fields (PEMF) that deliver broadband, wide spectrum, nonthermal photons and electrons deep into biological tissue. Electromedicine or electromagnetic healing are the terms applied to such developments in the ELF, RF, IR, visible or UV band. With short term, non-contacting exposures of several minutes at a time, such high voltage Tesla PEMF devices may represent the ideal, noninvasive therapy of the future, accompanied by a surprising lack of harmful side effects. A biophysical rationale for the benefits of BEM healing a wide variety of ...
Background: The influence of electromagnetic fields on the health of humans and animals is still an intensively discussed and scientifically investigated issue (Prakt Tierarzt 11:15-20, 2003; Umwelt Medizin Gesellschaft 17:326-332, 2004; J Toxicol Environment Health, Part B 12:572-597, 2009). We are surrounded by numerous electromagnetic fields of variable strength, coming from electronic equipment and its power cords, from high-voltage power lines and from antennas for radio, television and mobile communication. Particularly the latter causes controversy, as everyone likes to have good mobile reception at anytime and anywhere, whereas nobody wants to have such a basestation antenna in their proximity ...
On January 13, 2016, was published in the journal PLoS ONE an article ?Anthropogenic Radio-Frequency Electromagnetic Fields Elicit Neuropathic Pain in an Amputation Model? by Bryan Black, Rafael Granja-Vazquez, Benjamin R. Johnston, Erick Jones, and Mario Romero-Ortega.. Claims made by the authors made some headlines in the news media. Unfortunately, the article is not worthy any attention and should be immediately retraced and returned to the authors for additional experiments. It is simply a case of bad science.. The major problem with the article is the radiation dosimetry and temperature measurement of the skin.. The authors claim that exposing rats to level of RF-EMF mimicking levels emitted by cell towers, the temperature of the skin of the animals increased by 2.1oC (!!!). This would mean, for humans, rise of skin temperature from the normal 36.6oC to some 38.7oC. This should be occurring, according to the study, in response to cell tower radiation ? meaning just walking through the city ...

Word Heath Organisation (WHO) outlined in 2005 recommendations, how to treat people suffering from the functional impairment electrohypersensitivity in its document "Electromagnetic fields and public health". Unfortunately the reduction of electromagnetic fields was not considered as a treatment option. The aim of the current study was to shield the computer user from the emitted electromagnetic irradiation and fields and to correlate that to the subjective symptoms reported by electrohypersensitive volunteers. The irradiation of the shielding cabinets was recorded. They housed either separate computer screens or whole laptops. When the volunteers had used the shielding cabinet for 1-7 years, they were able work with their computers whole working day, Those who had used the shielding cabined for 2-3 months were partially symptom free. The person who had used the cabinet only for 1 week reported some alleviation of her nausea. In conclusion: it seems that reducing the electromagnetic irradiation ...

In shifting positions around an atomic nucleus, an electron generates energy and emits a magnetic resonance of specific frequency. Thus, the magnetic resonance field frequency of the various body tissues and organs is a product of the individual atomic, molecular and cellular frequencies specific to the molecules that constitute the particular tissue or organ. PEMF therapy therefore confuses the specific inherent magnetic resonance and temporarily modifies it in each atom, molecule, cell, and thus, tissue and organ. From the perspective of biophysics, physiological markers represent a level of "order or disorder" in the magnetic resonance of a normal atom that correlates to internal and external factors. The Pulsed Electro-Magnetic Fields generated by PEMF therapy devices provide sufficient energy to affect the magnetic resonance of the atom as the electron is energized. When a disruption in the magnetic resonance occurs, the magnetic resonance of the electrons at the atomic level also exhibits ...
WEDNESDAY, March 29, 2017 (HealthDay News) -- On-the-job exposure to electromagnetic fields may double the risk of developing amyotrophic lateral sclerosis (ALS), a degenerative disease of the nervous system, a new study suggests.. Electric company linemen, welders, sewing machine operators and airplane pilots are all people in occupations that could boost the chances of getting the always-fatal disease, said senior researcher Roel Vermeulen.. "Essentially, these are jobs where workers are placed in close proximity to appliances that use a lot of electricity," said Vermeulen, an associate professor of environmental epidemiology at Utrecht University in the Netherlands.. However, even people holding these jobs still have a low overall risk of ALS, said neurologist Dr. Catherine Lomen-Hoerth, director of the ALS Center at the University of California, San Francisco Medical Center.. Only one in 100,000 people will get ALS -- sometimes called Lou Gehrigs disease -- during their lives, so even a ...

A magnetic field measurement apparatus includes an irradiation portion, a gas cell, a measurement unit (polarization separation unit, light receiving portion, signal processing circuit), and a magnetic shield. The magnetic shield is formed in a elongated hollow shape having openings at both sides thereof. The gas cell, in which gaseous atoms are sealed, is disposed in a hollow area of the magnetic shield. The irradiation portion irradiates irradiation light including linearly polarized light adjusted so that the vibration direction of an electric field coincides with the axis direction of the magnetic shield onto the gaseous atoms sealed in the gas cell along a direction perpendicular to the axis of the magnetic shield. The measurement unit measures a rotational angle of a polarization plane of the irradiation light that has been irradiated by the irradiation portion and passed through the gaseous atoms.
National Grid had applied for Development Consent for a new power line to enable the connection of the proposed new Hinkley Point C nuclear power station. The application was considered by the Planning Inspectorate who made a recommendation to the Secretary of State, and on 19 Jan 2016, the Secretary of State accepted that recommendation and granted Development Consent (subject to various conditions).. In the course of considering the application, EMFs were looked at in depth. National Grid provided information in its Environmental Statement, the Inspectorate asked several Written Questions, and EMFs were a major part of one of the issue Specific Hearings.. The conclusions of the Planning Inspectorate on health and wellbeing including EMFs was:. ...
Dr Cecconi said that little had been done to study the potential role for ELF-EMF on the development of mammalian reproduction so their study was designed to see whether ELF-EMF could affect ovarian follicle development in mice.. They exposed isolated mouse ovarian follicles that were at the pre-antral development stage for five days to ELF-EFM at 33Hz or 50Hz frequencies. On day five, only around a third of the follicles exposed to 33Hz and half of those exposed to 50Hz developed antral cavities compared with 80% of controls.. "We dont know yet why this happens but our results indicate ELF-EMF may affect the regulatory mechanism controlling the somatic (non-germ) cells in the follicle.". Dr Cecconi said that more research would be needed to discover exactly how ELF-EMF was impairing the physiological process. It was also important to undertake research to see whether ELF-EMF exposure produced a similar effect on human ovarian follicles.. "At this stage we have no idea whether the same effect ...

Tiny electrical currents exist in the human body due to the chemical reactions that occur as part of the normal bodily functions, even in the absence of external electric fields. For example, nerves relay signals by transmitting electric impulses. Most biochemical reactions from digestion to brain activities go along with the rearrangement of charged particles. Even the heart is electrically active - an activity that your doctor can trace with the help of an electrocardiogram.. Low-frequency electric fields influence the human body just as they influence any other material made up of charged particles. When electric fields act on conductive materials, they influence the distribution of electric charges at their surface. They cause current to flow through the body to the ground.. Low-frequency magnetic fields induce circulating currents within the human body. The strength of these currents depends on the intensity of the outside magnetic field. If sufficiently large, these currents could cause ...
The aim of the present study was to assess whether exposure to the combination of an extremely low frequency magnetic field (ELF-MF; 60 Hz, 1 mT or 2 mT) with a stress factor, such as ionizing radiation (IR) or H2O2, results in genomic instability in non-tumorigenic human lung epithelial L132 cells. To this end, the percentages of G2/M-arrested cells and aneuploid cells were examined. Exposure to 0.5 Gy IR or 0.05 mM H2O2 for 9 h resulted in the highest levels of aneuploidy; however, no cells were observed in the subG1 phase, which indicated the absence of apoptotic cell death. Exposure to an ELF-MF alone (1 mT or 2 mT) did not affect the percentages of G2/M-arrested cells, aneuploid cells, or the populations of cells in the subG1 phase. Moreover, when cells were exposed to a 1 mT or 2 mT ELF-MF in combination with IR (0.5 Gy) or H2O2 (0.05 mM), the ELF-MF did not further increase the percentages of G2/M-arrested cells or aneuploid cells. These results suggest that ELF-MFs alone do not induce ...
However, it is the opinion of ICNIRP that the scientific literature published since the 1998 guidelines has provided no evidence of any adverse effects below the basic restrictions and does not necessitate an immediate revision of its guidance on limiting exposure to high frequency electromagnetic fields…..With regard to non-thermal interactions, it is in principle impossible to disprove their possible existence but the plausibility of the various non-thermal mechanisms that have been proposed is very low. In addition, the recent in vitro and animal genotoxicity and carcinogenicity studies are rather consistent overall and indicate that such effects are unlikely at low levels of exposure. Therefore, ICNIRP reconfirms the 1998 basic restrictions in the frequency range 100 kHz-300 GHz until further notice ...
EMF Dangers. Did you know that sleeping with an electric blanket might actually increase your chances of breast cancer? There are hidden dangers in our electrical appliances most of us dont suspect.. Today I wanted to share with you the hidden dangers of EMFs and then give you some tips on how to reduce your exposure.. What Is EMF?. Electric and magnetic fields (EMF) are areas of energy that surround any electrical device. EMFs are produced by electrical appliances, power lines and electrical wiring.. Electric fields are easily shielded or weakened by walls and other objects, however, magnetic fields are not. Since magnetic fields are more likely to penetrate the body, they are the component of EMFs that are usually studied in relation to cancer.. How Are EMFs Related to Breast Cancer?. It begins with the hormone known as melatonin, which is secreted by the pineal gland.. Melatonin is known to play a major role in cancer prevention and longevity. One of its primary functions is to regulate ...
The evaluation of the exposure from mobile communication devices requires consideration of electromagnetic fields (EMFs) over a broad frequency range from dc to GHz. Mobile phones in operation have prominent spectral components in the low-frequency (LF) and radio-frequency (RF) ranges. While the exposure to RF fields from mobile phones has been comprehensively assessed in the past, the LF fields have received much less attention. In this study, LF fields from mobile phones are assessed experimentally and numerically for the global system for mobile (GSM) and universal mobile telecommunications system (UMTS) communication systems and conclusions about the global (LF and RF) EMF exposure from both systems are drawn. From the measurements of the time-domain magnetic fields, it was found that the contribution from the audio signal at a normal speech level, i.e., -16 dBm0, is the same order of magnitude as the fields induced by the current bursts generated from the implementation of the GSM ...
Magnetic resonance imaging (MRI) has become an important diagnostic tool with an ongoing dynamic development towards application of increasing static magnetic flux densities and consequently, exposures to electromagnetic fields (EMF) of increasing radio frequencies (RF). This raises particular concern metallic implants could lead to excess tissue heating and consequently, to thermal tissue damage. In thorax surgery the intersected sternum is reconnected by metallic sutures (cerclages). To investigate whether patients with such implants can be accepted for MRI and whether there may be limitations with regard to static magnetic fields, by numerical anatomical and thermal modelling MRI induced tissue heating was assessed for magnetic flux densities 1.5 T, 3 T, 4 T and 7 T. Results show that overall tissue temperature increased with increasing RF EMF frequency. However, even for setting MRI exposure parameters at maximum permissible level partial body heating remained marginally affected and even at local

Our finding of large-diameter colloid droplets in the cytoplasm of thyrocytes, several droplets within the same cell and droplets in close proximity to small lysosomes in rats exposed to power-frequency EMF points to increased stimulation of follicular cells with TSH. The clear sign of this stimulation at the light microscopic level was an increase in the follicular epithelium height and a reduction in the colloid mass, which was supported by the stereological quantification results. Activation index of the thyroid gland, derived from the calculated values of the volume density of follicular epithelium and the volume density of colloid, is a stereological parameter used for correlation to the level of plasma TSH. Based on experimental studies on rats involving TSH measurements in peripheral blood and stereological analysis of thyroids, Kalisnik (Kalisnik, 1981) was able to show a positive correlation between the thyroid activation index and the plasma TSH. In this respect, we found that the ...

Electromagnetic fields are able to promote axonal regeneration in vitro and in vivo. Repetitive transcranial magnetic stimulation (rTMS) is used routinely in neuropsychiatric conditions and as an atraumatic method to activate descending motor pathways. After spinal cord injury, these pathways are disconnected from the spinal locomotor generator, resulting in most of the functional deficit. We have applied daily 10 Hz rTMS for 8 weeks immediately after an incomplete high (T4-5; n = 5) or low (T10-11; n = 6) thoracic closed spinal cord compression -injury in adult rats, using 6 high- and 6 low-lesioned non-stimulated animals as controls. Functional recovery of hindlimbs was assessed using the BBB locomotor rating scale. In the ...
The rapidly pulsed magnetic gradient fields used in magnetic resonance imaging (MRI) studies generate electric fields in the body. As the induced electric field (E) is proportional to the rate of change of the pulsed magnetic field (B), pairs of positive and negative E pulses are produced with a duration t_r equal to the rise and fall times of the trapezoidal B pulses and separated by a delay t_d arising from the plateau of the trapezoid. The effects of these electric fields have long been a matter of concern, and have been addressed with many modeling studies and experiments on human subjects. Previous studies on the effects of electromagnetic fields on the nervous system have generally focussed on unwanted peripheral nerve stimulation (PNS) during full-body MRI, or on intended electromagnetic stimulation of cortical areas by coils placed on the scalp.. Modeling studies have shown how the E field can generate action potentials (APs) in axons near the surface of the body. Generally, the fields ...
Abstract: Electromagnetic fields (EMFs) inhibit the formation and differentiation of neural stem cells during embryonic development. In this study, the effects of prenatal exposure to EMF on the number of granule cells in the dentate gyrus of 4-week-old rats were investigated. This experiment used a control (Cont) group and an EMF exposed (EMF) group (three pregnant rats each group). The EMF group consisted of six offspring (n=6) of pregnant rats that were exposed to an EMF of up to 900 megahertz (MHz) for 60 min/day between the first and last days of gestation. The control group consisted of five offspring (n=5) of pregnant rats that were not treated at all. The offspring were sacrificed when they were 4 weeks old. The numbers of granule cells in the dentate gyrus were analyzed using the optical fractionator technique. The results showed that prenatal EMF exposure caused a decrease in the number of granule cells in the dentate gyrus of the rats (P,0.01). This suggests that prenatal exposure to ...
Ambient man-made electromagnetic fields (EMFs), across a range of frequencies, are a serious environmental issue. Yet most environmentalists know little about it, perhaps because the subject has been the purview of physicists and engineers for so long that biologists have lost touch with electromagnetisms fundamental inclusion in the biological paradigm. All living cells and indeed whole living beings, no matter what genus or species, are dynamic coherent electrical systems utterly reliant on bioelectricity for lifes most basic metabolic processes. It turns out that most living things are fantastically sensitive to vanishingly small EMF exposures. Living cells interpret such exposures as part of our normal cellular activities (think heartbeats, brainwaves, cell division itself, etc.) The problem is, man-made electromagnetic exposures arent "normal." They are artificial artifacts, with unusual intensities, signaling characteristics, pulsing patterns, and wave forms, that dont exist in nature. ...
A device for manipulating a molecule in vivo relative to a target tissue in three dimensions includes a support and at least one member affixed to and extending away from the support. The member has at least two discrete and separately activatable electrodes. The electrodes are configured to establish a first electromagnetic field between selected electrodes sufficient to manipulate a molecule relative to a target tissue. The electrodes are further configured to establish a second, typically higher-level, electromagnetic field sufficient to cause transient permeability of a cell membrane within the target tissue. A third electromagnetic field may also be applied to cause further translation of the molecule into an electropermeabilized cell and/or manipulated with respect to the tissue. Thus three-dimensional manipulation of the molecule relative to the target tissue is effected to optimize a desired positioning thereof, such as entry into a cell.

The United Kingdom Childhood Cancer Study, a population-based case-control study covering the whole of Great Britain, incorporated a pilot study measuring electric fields. Measurements were made in the homes of 473 children who were diagnosed with a malignant neoplasm between 1992 and 1996 and who were aged 0-14 at diagnosis, together with 453 controls matched on age, sex and geographical location. Exposure assessments comprised resultant spot measurements in the childs bedroom and the family living-room. Temporal stability of bedroom fields was investigated through continuous logging of the 48-h vertical component at the childs bedside supported by repeat spot measurements. The principal exposure metric used was the mean of the pillow and bed centre measurements. For the 273 cases and 276 controls with fully validated measures, comparing those with a measured electric field exposure |/=20 V m(-1) to those in a reference category of exposure |10 V m(-1), odds ratios of 1.31 (95% confidence interval 0
Proton radiography is a useful diagnostic of high energy density (HED) plasmas under active theoretical and experimental development. In this paper, we describe a new simulation tool that interacts realistic laser-driven point-like proton sources with three dimensional electromagnetic fields of arbitrary strength and structure and synthesizes the associated high resolution proton radiograph. The present tools numerical approach captures all relevant physics effects, including effects related to the formation of caustics. Electromagnetic fields can be imported from particle-in-cell or hydrodynamic codes in a streamlined fashion, and a library of electromagnetic field "primitives" is also provided. This latter capability allows users to add a primitive, modify the field strength, rotate a primitive, and so on, while quickly generating a high resolution radiograph at each step. In this way, our tool enables the user to deconstruct features in a radiograph and interpret them in connection to ...
McCraty explains in "The Energetic Heart". "The heart generates the largest electromagnetic field in the body. The electrical field as measured in an electrocardiogram (ECG) is about 60 times greater in amplitude than the brain waves recorded in an electroencephalogram (EEG)." The heart electromagnetic field extends up to several feet away from the body in a 360-degree radius. These are the conclusion of a paper recently published on the Journal of Medical Hypothesis: "Although in physiology the heart is often referred to as a simple piston pump, there are in fact two additional features that are integral to cardiac physiology and function.. First, the heart as it contracts in systole, also rotates and produces torsion due to the structure of the myocardium. Second, the heart produces a significant electromagnetic field with each contraction due to the coordinated depolarization of myocytes producing a current flow. Unlike the electrocardiogram, the magnetic field is not limited to volume ...
