The Appeal highlights WHOs conflicting positions about EMF risk. WHOs International Agency for Research on Cancer classified Radiofrequency radiation as a Group 2B "Possible Carcinogen" in 2011, and Extremely Low Frequency fields in 2001. Nonetheless, WHO continues to ignore its own agencys recommendations and favors guidelines recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). These guidelines, developed by a self-selected group of industry insiders, have long been criticized as non-protective ...
At workplaces, special regulations apply. Here the exposure limits for the general public can be exceeded. At European level, the Directive 2013/35/EU of the European Parliament and of the Council on the "minimum health and safety requirements regarding the exposure of workers to the risks arising from physical agents (electromagnetic fields)" came into force on June 26, 2013. The rules contained therein shall be implemented into national law by all EU Member States through corresponding laws, regulations or administrative provisions by July 1, 2016. The regulations are based on the recommendations of the International Commission on Non-Ionizing Radiation Protection (ICNIRP). In the directive, the following limits are specified in a number of tables for different frequency ranges from 0 Hz to 300 GHz: ...
Controversy over cell phones in trains. A letter from T. Hondou in the Journal of the Physical Society of Japan has been widely reported in newspapers. Hondou claims that the simultaneous use of a number of mobile phones in an area with a reflective boundary, such as a commuter train, could create a level of exposure to electromagnetic fields that could exceed the guidelines of the International Commission on Non-Ionizing Radiation Protection. Other experts dispute his conclusions. Some have pointed out that the author used calculations suited to far-field exposure rather than Specific Absorption Rate - appropriate for near-field exposure. In addition, it has been claimed that he underestimated the dissipation of electromagnetic fields that would occur in a train with many people inside..

Hundreds of studies have already demonstrated the severely deleterious health effects of living near radio and microwave broadcast towers. Also, review the information on irrelevance of present SAR standards. The United States Environmental Protection Agency (EPA) itself acknowledges that current Federal Communications Commission (FCC) radiation protection standards are inadequate and do not account for all possible harmful effects of RFR, in particular the non-thermal effects that are of particular relevance to the radiation utilized by WiFi. In a July 16, 2002 letter from Norbert Hankin of the EPAs Center for Science and Risk Assessment, Radiation Protection Division to Janet Newton, President of The EMR Network, Mr. Hankin writes: "The FCCs current exposure guidelines, as well as those of the Institute of Electrical and Electronics Engineers (IEEE) and the International Commission on Non-Ionizing Radiation Protection, are thermally based, and do not apply to chronic, non-thermal exposure ...
OTTAWA -- An international study which debunks research linking cellphones to cancer risks received major funding from wireless manufacturers.. The World Health Organizations International Agency for Research on Cancer classified radio frequency emitted by wireless devices as possibly carcinogenic, but a panel of international scientists recently published a study challenging these findings.. The International Commission on Non-Ionizing Radiation Protection - composed of scientists from Britain, the United States and Sweden - said evidence is mounting against the hypothesis cellphones may cause cancer despite the findings of IARC.. But in the studys conflict of interest disclaimer, the panel acknowledged it received support from the wireless industry to conduct the research. A number of organizations, including the Mobile Manufacturers Forum, were cited as sources of funding.". Kristy Kirkup reports for the Toronto Sun July 6, 2011. [2]. ...
SAR values were several orders of magnitude lower than the limit of the International Commission on Non-Ionizing Radiation Protection (ICNRIP) (0.4 W/kg average SAR). There was a significant difference in comet assay parameters between the exposed and the control group suggesting, in the authors view, that "MW had an impact on DNA damage in peripheral blood lymphocytes of workers." In addition, micronucleus test parameters were significantly increased in the exposed group as compared to the control. The concentration of glutathion was decreased and the concentration of MDA was increased in the exposed group as compared to the control group, suggesting oxidative stress in workers exposed to MW. Conclusion. In the authors view, the results of this study "suggest that pulsed microwaves from working environment can be the cause of genetic and cell alterations and that oxidative stress can be one of the possible mechanisms of DNA and cell damage indicating that some biological effects are likely to ...

The Bureau also provides radiation protection and safety advice to other federal departments, such as Industry Canada, Transport Canada, Solicitor General, the Labour Programme of Human Resources and Social Development Canada, etc., ...
Non-ionizing (or non-ionising) radiation refers to any type of electromagnetic radiation that does not carry enough energy per quantum to ionize atoms or molecules that is, to completely remove an electron from an atom or molecule.[1] Instead of producing charged ions when passing through matter, the electromagnetic radiation has sufficient energy only for excitation, the movement of an electron to a higher energy state. The region at which radiation becomes considered as "ionizing" is not well defined, since different molecules and atoms ionize at different energies. The usual definitions have suggested that radiation with particle or photon energies less than 10 electronvolts (eV) be considered non-ionizing. Another suggested threshold is 33 electronvolts, which is the energy needed to ionize water molecules. The light from the Sun that reaches the earth is largely composed of non-ionizing radiation, since the ionizing far-ultraviolet rays have been filtered out by the gases in the atmosphere, ...
This Presidential Report from the National Council on Radiation Protection and Measurements (NCRP) has been prepared at the request of the Food and Drug Administration (FDA). FDA has the responsibility for regulating the manufacture of electronic products that emit ionizing and nonionizing radiation and is working with the Transportation Security Administration (TSA), which has the responsibility of providing security measures for transportation activities. The FDA asked the NCRP for advice on radiation protection issues concerning exposure to ionizing radiation from radiation-producing devices used for non-medical security purposes. These devices, particularly x-ray scanning systems, are being evaluated by various agencies (e.g., U.S. Customs Service and TSA) for use in security screening of humans. The use of such scanning devices involves a broad societal decision that needs to be made through appropriate procedures by the authorities utilizing the x-ray producing electronic products (and ...

Ionizing radiation has enough energy to remove tightly bound electrons from atoms, thus creating ions. This is the type of radiation that people usually think of as radiation. We take advantage of its properties to generate electric power, to kill cancer cells, and in many manufacturing processes. Nonionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons. Examples of this kind of radiation are sound waves, visible light and microwaves. ...

To review the potential optical radiation hazards from infrared eye-tracking systems when exposure durations are continuous throughout the day. Emphasis is placed upon the use of eye-tracking for gaze-based communication for severely disabled persons, which requires exposure of the eyes throughout a day over many years. Although there exist exposure guidelines from the International Commission on Non-Ionizing Radiation (ICNIRP) for infrared exposure and a CIE Standard (S-009) for photobiological safety of lamps and lamp systems, the lengths of exposure employed in this type of interface technology for disabled users may exceed the durations envisioned in the current exposure guidelines and standards. Abnormalities in the eye behaviour of severely disabled users may also require special treatment in safety standards ...
Many items and compounds that produce ionizing and non-ionizing radiation are regulated by Federal, State and International Governments due to their hazardous nature and need for control via licensing or registration. Other forms of non-ionizing radiation may have safety guidelines published by non-governmental scientific bodies such as, but not limited to, the American National Standards Institute (ANSI), the International Committee of Non-Ionizing Radiation Protection (ICNIRP) and the American Conference of Governmental Industrial Hygienists (ACGIH). A Radiation Safety Office resides within the Research Safety Bureau in Environmental Health and Safety; part of the Division of Law Enforcement and Safety. The Office is staffed by the Radiation Safety Officer (RSO) for the University, and two Environmental Health Managers that are responsible for maintaining licenses and registrations for the University to legally possess and use hazardous forms of ionizing radiation that are controlled by the ...

The risks to public health of NIR, whether in the form of UV light, radio waves from wireless devices, or electric and magnetic fields associated with electrical power systems, is currently a cause of great concern among members of the public and lawmakers. But in order to separate established science from speculation and make informed decisions about how to mitigate the risks of NIR and allocate precious resources, policymakers, manufacturers, and individuals need a comprehensive source of up-to-date information based on the current scientific evidence. Written by a team of experts in their fields, this book is that source. Among other things, it: Summarizes scientific findings on the safety of different forms of NIR and the rationale behind current standards Describes devices for monitoring NIR along with the established and potential hazards of each form Explores proper protections against UV light and lasers, RF radiation, ELF fields and other forms of NIR Discusses how to avoid injuries ...
Cordell E Logan. Quantum physics seeks to describe the tiniest particles that make up matter. These particles do not behave with the predictability of linear equations. A quantum of electromagnetic energy is regarded as a discrete particle having zero mass, no electric charge, and an indefinitely long lifetime.. Biophotons are characterized by a high degree of order, and can be described as a biological laser light that is capable of interference not achievable by ordinary incoherent light. The high coherency lends the biophoton wave with the capacity of creating order and transmitting information while chaotic, incoherent light simply transmits energy. Electromagnetic signals can be called biophotons.. The biophoton field is a rigidly structured field of information and regulation that combines the single parts of an organism in a holographic manner at the speed of light. It coordinates single cells with other cells. Research has indicated that the biophoton wave is emitted from the chromatin ...
Personally, I think it morally imperative to possess as much accurate information regarding EMFs/RFRs/ELFs, plus the coming 5G millimeter waves, so we can prepare ourselves for battles extraordinaire-literally and figuratively, especially if or when big tech and microwave providers and platforms have standardized consensus science experts testify, and the engaging way state and federal regulatory agencies buy into USA being Number 1 in tech, as currently is being steamrolled over many of us in various cities around the country..

1. Scientists with strong Industry ties no longer tolerated as "experts" on International Panel.. It is well know that too many "experts", who advise international agencies such as IARC (International Agency for Research on Cancer) and ICNIRP (International Commission for Non-Ionizing Radiation Protection), have strong industry connections. These agencies are the ones that set standards and establish what is and what isnt harmful based on the "best available" research. That dominance by "industry experts" is beginning to crumble ever so slowly.. A TV documentary on French television took a jab at the shenanigans that go on behind the scene. An excellent summary is available at Microwave News.. IARC, an arm of the World Health Organization (WHO), responds to criticism that too many of its expert panel have strong industry ties. One member, Anders Ahlbom, was removed from the RF Cancer Panel that met in Lyon France during the week of May 23, 2011. For a list of participants click here.. Other ...
There are two basic types of radiation: ionizing and non-ionizing. Examples of non-ionizing radiation include microwaves and electromagnetic fields. Types of ionizing radiation include gamma, beta and x-rays. Radiation therapy treatments involve one or more of these three types of ionizing radiation.. Ionizing radiation cant be detected with any of the five human senses. Because of this, special instruments, such as Geiger counters and ionization chambers, are used to detect radiation and to measure radiation levels. Exposure to radiation doesnt cause people to glow in the dark or make them radioactive.. Everyone is exposed to radiation everyday. Most of this non-occupational radiation exposure comes from natural sources. The table below lists sources and average exposures from both natural and man-made sources of radiation:. ...
The International EMF Scientist Appeal was initially signed by 190 scientists from 39 nations. These scientists have collectively published over 2,000 peer-reviewed papers on the biological or health effects of non-ionizing radiation, part of the EMF spectrum that includes Extremely Low Frequency fields (ELF) used for electricity, or Radio Frequency radiation (RFR) used for wireless communications.. First, we invite you to view Dr. Martin Blanks three-minute video announcing the Appeal. Dr. Blank has had over 30 years of experience conducting EMF research at Columbia University and is a past president of the International Bioelectromagnetics Society. In his own words, Dr. Blank gives a compelling explanation of the major health crisis we are facing due to increasing levels of environmental pollution from growing and expanding EMF sources.. ...
This chapter reviews sources, health effects, and policies for limiting human exposure to ionizing and non-ionizing radiation. Technological developments involving exposure to electromagnetic fields bring social and economic benefits to large sections of society but the health consequences of these developments can be difficult to predict and manage. Biological effects and our knowledge of the health effects of these forms of energy varies: For ionizing radiation, ultraviolet radiation, and power frequency fields numerous state-of-the art epidemiologic and toxicologic investigations, covering a variety of endpoints, have been undertaken. While numerous studies of static and radiofrequency fields have been completed, much of the key research is yet to be done; and for intermediate frequencies, only scant information is available.Of numerous health effects that have been studied in relation to various aspects of radiation, cancer has received the most attention and appears to be an outcome with the
There are few industries these days that put the welfare of those affected by their policies or toxins above the profit to be made by following those policies and creating those toxins. It is now commonplace for industries to hire PR people -spin doctors- to respond to the publics concerns, and We Energies has an exceptional crew at work in this capacity.. It is true, as We Energies Customer Services Vice-President Joan Shafer states, that the radiation from their radiowave-transmitting "smart" meters is allowable under present FCC regulations concerning non-ionizing radiation. However, the present FCC regulations were based on inaccurate assumptions and have not been updated as these assumptions were proven false. The regulation is in about the same place as regulation re negative effects of cigarette smoking or asbestos was 30 or 40 years ago.. In just a few decades, with the explosion of wireless signals of radio and TV broadcasts, radar, military applications, microwave towers and cell ...

This article demonstrates a step towards awareness-raising of the public on the issue of the long-term effects of non-ionizing radiation. It has been scientifically shown that wireless gadgets, high-voltage power lines and certain household appliances emit waves having detrimental health effects, especially on children. We must cease spreading the impression that certain damaging biological effects are generated by "fear" of waves. Electrosmog can cause, among others, infertility and cancer in man, blindness in calves, damage to trees, and the disappearance of bees ...
Silicon pixel detectors are at the core of the current and planned upgrade of the ATLAS experiment at the LHC. Given their close proximity to the interaction point, these detectors will be exposed to an unprecedented amount of radiation over their lifetime. The current pixel detector will receive damage from non-ionizing radiation in excess of 10(15) 1 MeV n(eq)/cm(2), while the pixel detector designed for the high-luminosity LHC must cope with an order of magnitude larger fluence. This paper presents a digitization model incorporating effects of radiation damage to the pixel sensors. The model is described in detail and predictions for the charge collection efficiency and Lorentz angle are compared with collision data collected between 2015 and 2017 (,= 10(15) 1 MeV n(eq)/cm(2)).. ...

Optical coherence tomography (OCT) is a recently developed imaging technologythat has stimulated considerable interest in the fields of medicine, biology, andmaterial science. The unique capability of OCT to noninvasively explore microstructurewithin turbid media using nonionizing radiation has opened the door to applicationssuch as optical biopsy, surgical guidance, studies of developmental biology,and quality control of advanced composites in situ.. The technological innovations that have led to the current success of OCT aremanifold and have been published in the scientific literature of optical communications,optical engineering, applied physics, and biomedical engineering. Similarly, theapplications of OCT have been separately described in the publications of the relevantfields. The diversity of these publications has led to a need for a comprehensivehandbook describing OCT and detailing the advances. The aim of this book, then, isto address this need and to serve as a repository for ...
Title:1950 MHz Electromagnetic Fields Ameliorate Aβ Pathology in Alzheimers Disease Mice. VOLUME: 12 ISSUE: 5. Author(s):Ye Ji Jeong, Ga-Young Kang, Jong Hwa Kwon, Hyung-Do Choi, Jeong-Ki Pack, Nam Kim, Yun-Sil Lee and Hae-June Lee.

Keywords:Alzheimers disease mice, β-amyloid, BACE1, microarray, radiofrequency electromagnetic field.. Abstract:The involvement of radiofrequency electromagnetic fields (RF-EMF) in the neurodegenerative disease, especially Alzheimers disease (AD), has received wide consideration, however, outcomes from several researches have not shown consistency. In this study, we determined whether RF-EMF influenced AD pathology in vivo using Tg-5xFAD mice as a model of AD-like amyloid β (Aβ) pathology. The transgenic (Tg)-5xFAD and wild type (WT) mice were chronically exposed to RF-EMF for 8 months (1950 MHz, SAR 5W/kg, 2 hrs/day, 5 days/week). Notably, ...
Questions continue to arise about cell phones and their contribution to certain cancers. Even the National Cancer Institute (NCI) has raised some concern about extensive cell phone use. The NCI explains that cell phones emit radio frequency energy in the form of non-ionizing radiation. In other words, a cell phone basically lets off radio waves which are absorbed by the nearest tissues of the body. If a person carries a phone in their pocket all day long, energy can be absorbed into the persons side and midsection.. How does this energy affect the cells over time?. Does this constant exposure disrupt cellular processes, especially when held up to the brain?. While the NCI says that a cell phones non-ionizing radiation has not been proven for carcinogenic activity, other studies may prove otherwise.. More than 15 hours of cell phone use per month may triple brain cancer risk. French scientists are now reporting on a new cohort study showing how extensive cell phone use can increase ones risk ...
youtube]http://www.youtube.com/watch?v=_bBbQv5KBms[/youtube]. http://www.emfnews.org. 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 ...
Most animals will only consume food in its natural, unprocessed state, but humans actually go out of their way to render food nutritionally worthless before eating it. Think about all the prepackaged and processed foods we purchase and consume annually.. Its no wonder the state of our health is in dire straits. Microwaves are a source of electromagnetic energy (a form of nonionizing form of radiation) electronically generated. When penetrating the aliments, they trigger an inner rotation of the water molecules inside the food. This rotation triggers a friction between the molecules and the result is a rapid growth in temperature.. Microwave ovens work physically, biochemically and physiologically, producing ions and various free radicals, which destroy viruses and bacteria, but not toxins and microtoxins. The experts have concluded that food cooked in microwaves loses between 60% and 90% of its vital energy and, at the same time, the structural disintegration processes accelerates. Also, the ...
TY - JOUR. T1 - Magnetic resonance imaging of anatomic and dynamic defects of the pelvic floor in defecatory disorders. AU - Fletcher, Joel Garland. AU - Busse, R. F.. AU - Riederer, Stephen J. AU - Hough, David M. AU - Gluecker, T.. AU - Harper, C. M.. AU - Bharucha, Adil Eddie. PY - 2003. Y1 - 2003. N2 - OBJECTIVE: Endoanal ultrasound identifies anal sphincter anatomy, and evacuation proctography visualizes pelvic floor motion during simulated defecation. These complementary techniques can evaluate obstructed defecation and fecal incontinence. Our aim was to develop a single, nonionizing, minimally invasive modality to image global pelvic floor anatomy and motion. METHODS: We studied six patients with fecal incontinence and seven patients with obstructed defecation. The anal sphincters were imaged with an endoanal magnetic resonance imaging (MRI) coil and endoanal ultrasound (five patients). MR fluoroscopy acquired images every 1.4-2 s, using a modified real-time, T2-weighted, single-shot, ...
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 ...
The first point I should make is that they used radiation at 918MHz (similar to a GSM mobile phone in this respect) but it was neither pulsed nor modulated, so it cannot be regarded in any way as being equivalent to real mobile phone or Wifi radiation.. Unmodulated radiation is less biologically active. The non-thermal effects of unmodulated radio frequency radiation are normally much weaker than modulated radiation and could even produce the opposite effect (this is called radiation hormesis, which has been studied mostly in relation to ionizing radiation, but it probably also applies to non-ionizing radiation).. Radiation hormesis. It is argued that living cells and organisms perceive the damaging effects of the radiation and put themselves into "repair mode". This includes boosting enzymes needed for cellular growth and regeneration and also triggering inflammation to increase the blood supply to the affected region. Provided these measures are successful, there may be no observable adverse ...
Now that we understand EMFs a bit better as well as the potential sources, what if any, is the potential impact on human health? Unlike the ionizing part of the electromagnetic spectrum which we clearly understand to damage DNA and cellular structure, there is very little chatter about non-ionizing radiation. Back in the late 1970s, you might remember that researchers found that children living close to power lines had an increased incidences of leukemia.[1] Additional epidemiological studies have found a doubling of risk for childhood leukemia with high residential exposure to ELF-EMFs.[2]. Considering that Wi-Fi networks, cell phones, and lap tops are virtually everywhere now, the impact of these fields on human health does merit precise and unbiased research. There is research being done but it is scarce and doesnt receive much attention. The National Institute of Environmental Health Sciences is conducting a large animal study to examine the impact of cell phone radiation to examine ...
With nearly 30 years of risk assessment experience, Gradient scientists bring sound science to the health risks and potential environmental impacts of both radiation and chemical exposures. Whether in the context of litigation, supporting environmentally sound site closure, or addressing public concerns, Gradient uses human health risk assessment to assess radioisotope concentrations in environmental media and evaluate the potential for cancer or other health risks. We place these risks in proper perspective compared to background radiation as an important element of risk communication. Moreover, Gradient scientists help draw the important health-risk distinctions between exposure to ionizing versus non-ionizing radiation (e.g., power-line electric and magnetic fields, cell phones, and radio waves).. Example Publications:. Goodman, JE; Nascarella, MA; Valberg, PA. 2009. "Ionizing radiation: A risk factor for mesothelioma." Cancer Causes Control 20:1237-1254.. Valberg, PA; Van Deventer, TE; ...
