How to protect yourself from Electromagnetic stress


I am a stressed man, and who can blame me? I have a kid on the way, trying to manage all my debts and at the same time I read and write about all the dangers radiation and EMF pose to us. In addition to this, I’m pretty sure all of the excess Electromagnetic energy being produced can’t be doing much good.
Let’s think about it for a minute, ten years ago, there was hardly any wireless technology out, the occasional phone and television remote being the only things that immediately pop into mind, as well as the few overhead power cables.

Now, let’s compare that to these days, we have Mobile phones, Mp3 Players and Laptops all of which are producing electromagnetic fields. A tangle of wires hang over our heads, telephone cables, power lines and the such, all leaking their own EMF’s. Towering telephone masts and Cell phone towers loom over us, showering us with radiation. In short, compared to then, there is so much more technology projecting waves that damage us on a cellular level.

I’m not sure about anyone else, but ten years ago, I felt much healthier and a lot less stressed (this may have been because I was 10 but who knows…) now a possible cause of all this is the aforementioned EMF, which constantly bombard our bodies. These fields actively attack our cells, damaging them on a molecular level, causing us to become fatigued, our metabolism to slow and lower our resistances to disease. And because of all this we become more and more stressed, so they key to alleviating this stress falls into making our bodies more resistant to the damage these EMF’s are unavoidably doing.

The most obvious way to combat the damage is to minimize the amount of time we expose ourselves to these EMF’s. By spending less time using our phones and other wireless electronics, we can decrease strength of EMF’s we are exposed to.
As an example, I play a lot of video games, mainly on the Xbox, so I was regularly holding onto a wireless controller for several hours on end, when I started to read about EMF’s however I immediately went out and bought a wired control. It wasn't much, but I did feel a very slight improvement in my health, whereas I used to feel run down after a couple of hours of playing, I now felt fine, well worth the money.
Another obvious way of minimizing the strength of the EMF’s, is to make sure you live far away from Cell phone towers and other powerful EMF producers, it may seem a trivial matter but it will make all the difference. In addition, by wearing magnetic jewellery you can help to counteract some EMF fields, a simple magnetic bracelet can make a world of difference.

You know how metal conducts electricity correct? Well
many of us have metal filling, and the EMF’s react with them the way you would expect it to. When the EMF passes through your body, the metallic fillings conduct trace amounts of the electromagnetic pulse, and does so repeatedly, gathering its own EMF overtime, producing it in your own mouth and I need not describe how that is damaging. If you can have these replaced with tooth-colored composite fillings, you should as it will lead to less damage from EMF overtime.

By improving your immune system your cells will naturally be more resistant to the damage the EMF’s will do. There are dozens of ways to improve your natural immune system, drinking lots of water and eating raw vegetables are both simple ways to give yourself a little boost. Upping your vitamin intake will help in more ways than one, as will taking several Probiotics over the course of a week.
To continue on the theme of Probiotics, the bodily stress caused by the EMF’s will cause your body to power through the good bacteria in your body, causing you to become more and more susceptible to diseases and illnesses, so by using Probiotics you can replenish the good bacteria at rate that should hopefully match the rate that the EMF’s cause them to die off.

When your body is regularly hit by powerful EMF’s it causes the micro-organisms in your body to produce an excess of neurotoxins as a response to the mass of minor infections your body has to start to defend itself against and due to the prior damage already caused, your body cannot cope with the mass of neurotoxins now flooding your system. So be sure to regularly purge your body of toxins, or the build up will cause further cell determination which in turn causes your body to create more neurotoxins, a never ending cycle.

Remember when your parents used to say, “Don’t sit to close to the TV, or your eyes will go square” well, they weren't far off. Newer televisions produce a much stronger EMF’s than older televisions, so sitting further away will cause the EMF produced by the TV to deal less damage to your body. The same idea also goes for computer screens, even now as I write this I’m leaning back in my chair, a kind of unconscious way of minimizing the damage done, other than sitting across the room of course.

As I mentioned in my previous post “Is an Apple that healthy?” your room should be one of the cleanest areas in your home, both physically and on a molecular level. So here are a few tips to decrease the amount of Radiation and the strength of the EMF’s in your room:

  • Remove any electrical wires than run under your bed.
  • Avoid having wireless devices in your room.
  • Substitute automatic electronic devices for manual non-electronic variants.
  • Swap any cordless phones for corded versions.

So with only a few alterations in your room, you can massively alter the strength of the EMF’s where you sleep. Never underestimate the damage that can be done whilst you sleep, because you aren't moving the EMF’s affect you far more directly, damaging the cells over the time you sleep.

With a few of these changes, you should be able to lessen the amount of EMF that effect you, which will be minimize the damage the done by the electromagnetic fields that run rampant across our landscapes. On a secondary note, there have been proven methods that can minimize or sometimes even neutralize EMF’s harmful effects, so in time, a more widespread way of neutralize the damage may become available. But until then, I hope the tips I have given you prove to be helpful!

Bees, Birds and Mankind. Destroying Nature by ‘Electrosmog’

"Today, unprecedented exposure levels and intensities of magnetic, electric, and electromagnetic fields from numerous wireless technologies interfere with the natural information system and functioning of humans, animals, and plants. The consequences of this development, which have already been predicted by critics for many decades, cannot be ignored anymore. Bees and other insects vanish; birds avoid certain places and become disorientated at others. Humans suffer from functional impairments and diseases. And insofar as the latter are hereditary, they will be passed on to next generations as pre-existing defects"  Ulrich Warnke

Cellphones and Brain Tumors - 15 Reasons for Concern


“In a world where a drug cannot be launched without proof that it is safe, where the use of herbs and natural compounds available to all since early Egyptian times are now questioned, their safety subjected to the deepest scrutiny, where a new food cannot be launched without prior approval, the idea that we can use mobile telephony, including masts, and introduce WiFi and mobile phones without restrictions around our 5 year olds is double-standards gone mad. I speak, not just as an editor and scientist that has looked in depth at all the research, but as a father that lost his beloved daughter to a brain tumour.”

An EBEA Report into the Exposure to high frequency electromagnetic fields, biological effects and health consequences (100 kHz-300 GHz)

This is a review of the scientific evidence on dosimetry, biological effects, epidemiological observations, and health consequences concerning exposure to high frequency electromagnetic fields.  ICNIRP was established to advance non-ionizing radiation protection for the benefit of people and the environment.

ICNIRP is a non-governmental organization in non-ionizing radiation in formal relations with the World Health Organization and the International Labour Office. It maintains a close liaison and working relationship with all international bodies engaged in the field of non-ionizing radiation protection, and interacts with radiation protection professionals worldwide through its close collaboration with the International Radiation Protection Association and its national societies.


Work is conducted in four standing committees - on Epidemiology, Biology, Physics and Optical Radiation - and in conjunction with appropriate international and national health and research organizations as well as universities and other academic institutions.

This is a link to a European BioElectromagnetics Association (EBEA) article about the Exposure to high frequency electromagnetic fields, biological effects and health consequences (100 kHz-300 GHz).

What is the International EMF Project?

What is the International EMF Project?

Background

Potential health effects of exposure to static and time varying electric and magnetic fields need scientific clarification. Electromagnetic fields of all frequencies represent one of the most common and fastest growing environmental influences, about which there is anxiety and speculation are spreading. EMF exposure now occurs to varying degrees to all populations of the world, and the levels will continue to increase with advancing technology. Thus, even a small health consequence from EMF exposure could have a major public health impact.
Concerns have been expressed that exposure to extremely low frequency (ELF) magnetic fields at power frequencies (50/60 Hz) could lead to an increased incidence of cancer in children and other adverse health effects. The evidence comes primarily from residential epidemiological studies. These studies suggest that children exposed to ELF magnetic fields have an associated increased risk of leukaemia.
Radio frequency (RF) fields are used to great benefits in many facets of everyday life, such as radio and TV transmission, telecommunications (eg mobile telephones), diagnosis and treatments of disease and in industry for heating and sealing materials. With the rapid introduction of mobile telecommunications devices, especially among the general public, there has been a focus on the problems associated with near field RF exposure to the head from the small radiating antenna of mobile phones. In addition, concerns persist that exposure to pulsed and amplitude modulated RF fields may cause specific health effects.
As societies develop, greater use of certain technologies leads to increasing exposure to static electric and magnetic fields. This is especially the case in industry, transport, power transmission, research and medicine. Possible health effects from static fields have never been properly assessed. Given the rapid expansion of medical devices and imminent introduction, potentially on a large scale, of magnetic levitation transport systems that use strong static magnetic fields, any health impacts need to be properly assessed.
As part of its charter to protect public health and in response to public concern over health effects of EMF exposure, the World Health Organization (WHO) established the International EMF Project in 1996 to assess the scientific evidence of possible health effects of EMF in the frequency range from 0 to 300 GHz. The EMF Project encourages focused research to fill important gaps in knowledge and to facilitate the development of internationally acceptable standards limiting EMF exposure.

Project objectives

Key objectives of the Project are to:
  • provide a coordinated international response to concerns about possible health effects of exposure to EMF,
  • assess the scientific literature and make a status report on health effects,
  • identify gaps in knowledge needing further research to make better health risk assessments,
  • encourage a focused research programme in conjunction with funding agencies,
  • incorporate the research results into WHO's Environmental Health Criteria monographs where formal health risk assessments will be made on exposure to EMF,
  • facilitate the development of internationally acceptable standards for EMF exposure,
  • provide information on the management of EMF protection programmes for national and other authorities, including monographs on EMF risk perception, communication and management, and
  • provide advice to national authorities, other institutions, the general public and workers, about any hazards resulting from EMF exposure and any needed mitigation measures.

Project activities

The mandate of the the International EMF Project is to assess the health and environmental effects of exposure to static and time varying electric and magnetic fields in the frequency range 0 - 300 GHz. For the purposes of the EMF Project, this range is divided into: static (0 Hz), extremely low frequency (ELF, >0-300 kHz), intermediate frequencies (IF, >300Hz to 10MHz), and radiofrequency (RF, 10 MHz-300 GHz) fields.
The EMF Project is located at the World Health Organization (WHO) headquarters in Geneva, Switzerland, since this is the only United Nations organization with a clear mandate to investigate detrimental health effects from exposure of people to non-ionizing radiation. The project is part of the Department of Public Health and Environment (PHE) in the Health Security and Environment (HSE) cluster.

Measuring Wireless Radiation

Measuring Wireless Radiation

To be really empowered when it comes to electromagnetic fields one has to learn to measure the location with a meter or detector. Otherwise, one is guessing what the exposures might be.

The very best way to measure would be with a microwave ‘spectrum analyzer’ that can tell you what your exposures are, with specificity regarding the exact frequencies present. A spectrum analyzer can cost tens of thousands of dollars so they are mostly used in industry and government. It is not a practical tool for most consumers, nor is it necessary. Instead, meters that measure composite power density are used, without the specific details of what frequencies are present. It is a very rare case when a spectrum analyzer will need to be brought in to identify and resolve a problem.

For the layman, the basic Electrosmog Meter is a handy choice for both detecting and measuring radiation in the lower end of the microwave band where cell towers transmit. Its bandwidth (range: 50MHz to 3.5 GHz) is too high to detect AM radio or amateur radio (except VHF and higher frequencies), and too low to detect 5.8 GHz cordless phones, radar, and higher frequency microwave transmissions. But it will detect cell phone, cell towers, TV, and FM radio transmissions, as well as microwave ovens.

A step up from the basic Electrosmog Meter is the newer 8 Gigahertz Electrosmog Meter that runs about $500. The advantage over the basic meter is it will pick up a much broader range of exposures, including portable phones on the high end as well as some new forms of Wi-Fi that operate at 5 Gigahertz (most are at 2.4 Gigahertz). The meter’s range is 10 MHz to 8 Ghz.

Several experts have compared the Electrosmog Meters with far more expensive European meters that run into the thousands of dollars, and find the Electrosmog Meters to be comparable, thus they are a real value in making microwave radiation measurement affordable to larger audiences.

The meters are fairly user-friendly once one is walked through the basics of how to use it.  We are confident school personnel can learn to use these meters if given a scale for a frame of reference in order to understand what the readings mean. There are several units of measurement to choose from. I personally use ‘microwatts per meter squared’ unit of measurement on the meter so I can compare the readings obtained with the scale prepared by the Institute for Bau Biologie & Ecology.

Many experts do not recommend the popular Trifield Meter for microwave measurements, although note the Trifield is considered very reliable for magnetic field measurements (except in high RF environments). When it comes to RF meters in particular, its best to buy a brand trusted by experts who use these meters in the course of their daily life and understand their reliability and quirks.

Detecting vs. Measuring

For simply detecting radio frequency radiation, instead of measuring it, an excellent meter is the Zapchecker 185, www.zapchecker.com. The Zapchecker, though only displaying relative readings, is highly sensitive and was developed for security personnel to detect hidden bugs and cameras. Its range is far broader than the TES-92 Electrosmog Meter. It also has a vibrate mode for undercover detection. Its very fast analog needle display and blinking LED light make EMF detection obvious and easy. For simply finding RF or MW sources so one can know to shield oneself from these sources it is a highly sensitive, excellent choice.

The Cheapest Way of Detecting Radiofrequency

It is possible to use a portable AM radio to detect some RF sources. First turn the radio dial between stations where there is no radio signal. Move about, and turn the radio antenna in all directions. When you hear static this means there is a source of radiofrequency present. As an experiment, place the AM radio near a Compact Fluorescent Bulb and listen to what happens. Next check out what happens near an operating cell phone or other items with a low frequency and high electric field. An AM radio can be a useful initial screen when no meters are available, but note it won’t pick up all sources, such as Wi-Fi, which is too high a frequency and not a strong enough electric field. Nonetheless, a simple inexpensive AM radio can be a good initial scout for microwave and RF fields on a low budget.

Australian Schools: Stop Exposing Children to Radiation from WiFi and 3G until long-term exposure is proven harmless

Why this is important
Australian school children are facing a massive health crisis if the government and education authorities continue to ignore the warnings on the potential long-term health effects from chronic exposure to electromagnetic radiation (EMR) from WiFi and 3G internet.
In 2011 the World Health Organisation’s (WHO) International Agency for Research on Cancer (IARC), classified this form of electromagnetic radiation as “possibly carcinogenic” - wireless technologies are now considered as a possible cancer causing agent.
In Australian schools children are being involuntarily exposed to low-intensity radiation for 6 hours a day, 5 days a week. This is unacceptable as there are safer wired options.
Many scientists and medical experts warn that environmental exposure to man-made EMR interferes with the body’s internal bioelectrical signals which may lead to "loss of wellbeing, disease and even death." (BioInitiative Report 2012)
There are no specific scientific studies on the long-term health effects of WiFi on children, yet this technology is being vigorously rolled out in schools without parental consent.
Based on the overall scientific evidence of harm, the Council of Europe have called for a ban on WiFi use in schools and urge governments to act swiftly.Some responsible governments and authorities overseas have banned or warned against WiFi use in schools. They have taken the precautionary approach in order to minimise children’s exposure to wireless radiation.
We need to urgently send a strong message to the Australian government urging them to do the same, and to put children’s health ahead of convenience and short term profits.
With each passing day of government inaction Australian children are increasingly exposed to the potential long-term health effects from EMR.Children are also most vulnerable as they absorb more radiation due to their thinner skulls, bones and developing cells.
Even the Australian Radiation Protection Nuclear Safety Agency (ARPANSA) states "research relating to children is limited and the possibility of harm cannot be completely ruled out."
Just like the case with smoking, the possibility of illness manifesting may not be known until after years of chronic, low-level exposure to wireless radiation. It could take another 15-20 years before we have conclusive scientific proof
As the debate intensifies between pro-industry experts and independent groups of scientists about evidence of biological harm, the fact remains that this convenient, yet untested wireless technology has not been proven to be harmless for long-term use.
Given the recent WHO reclassification and the overall scientific evidence of harm,we need to act now before the damage proves to be extensive and irreversible to our children and future generations.
Let’s urgently raise our voices and build an unprecedented petition calling on the Australian government to take an immediate precautionary approach to reduce children’s exposure to wireless radiation.
Stop the use of WiFi and 3G internet in schools until conclusive evidence proves low intensity, long-term exposure to be harmless.
Please sign this urgent petition and share it widely.

EMF: How close is too close?



E.M.F. Three little letters that strike terror into many hearts, but why?

Donna Shay, a Colorado citizen, asked Western to conduct an electric and magnetic field reading at her cabin that sits just outside a 115-kilovolt transmission line’s right-of-way. EMF readings determined about 1 milliGauss of exposure near her front door.

Mostly, it’s because we don’t understand electric and magnetic fields, or EMF.

The truth is people come into contact with these fields every day. EMFs occur naturally, like the magnetic field caused by currents deep inside Earth’s molten core. Manmade fields are also created by common appliances and equipment we depend on every day, like talking on a cell phone or heating up lunch in a microwave

At Western, our high-voltage transmission lines and substations give off EMF, which sometimes concerns landowners with lines over and near their property. To help allay concerns, Western’s electrical engineers will test landowners’ EMF exposures from our transmission lines on request. Rocky Mountain Electrical Engineer Ron Padget is one such engineer who helps landowners determine the EMF exposure on their property. “They’ve heard about EMF, but they don’t know what it is,” he said. “So when I do a reading of their property, I let them know the physics of [EMF] and the fact that we don’t know if it’s dangerous or not.

In fact, there is no official accepted “safe level” for EMF exposure; there is still considerable controversy and uncertainty surrounding the risks and long-term effects of EMF, but many sources defer to 1 milligauss.

There is also an important distinction between magnetic and electrical fields. Padgett explained, “Research shows electrical fields don’t have a harmful effect on humans, but researchers are still looking at the effects of magnetic fields.”
Electrical fields versus magnetic fields: What’s the difference?
Electric FieldMagnetic Field
Produced by voltage (amount of energy)Produced by current (flow of energy)
Easily shielded (weakened)Not easily shielded (weakened)
Measured in volts per meter (V/m)Measured in milliGauss (mG)
The World Health Organization is also conducting long-term studies into the effects of EMF, and you can learn more about EMF at the WHO’s EMF Project website.
Go the distance
To reduce exposure to EMF, distance is the key.
“While magnetic fields are not easily shielded by objects or barriers like walls, roofs and trees; the exposure drops significantly the farther you are from the source creating EMF,” said Padget. “It’s the inverse of the square rule. If you’re twice as far away from the source (like a transmission line) you only get a quarter of the exposure; it drops off very quickly.”
For example, if your exposure standing directly under a 230-kilovolt transmission line is 64 mG, then when you walk 52 feet away your exposure is only 16 mG; and if you stand 116 feet away then your exposure is only 4 mG.
Common EMF sources
  • Electric blankets: Topping the list for worst EMF exposure is electric blankets because although the output is small, their close proximity to people increases EMF exposure. You’re unlikely to cuddle with your hairdryer or nap under a transmission line.
  • Wireless electronics (cell phones, etc)
  • Power Lines
  • TVs and computers
  • Electric clocks
  • Hairdryers
  • Electric razors
  • Kitchen appliances
Check out other EMF sources and their exposure levels at the Environmental Protection Agency’s “EMF in Your Environment” booklet.
Prudent avoidance
While you can’t prevent EMF, you can limit your exposure by using what what the EPA calls “prudent avoidance.” In addition to not wrapping up in a plugged-in electric blanket, you might:
  • Move your motor-driven electric clocks or other electrical devices (like cell phones) away from your bed.
  • Stand away from an operating microwave oven or other appliances that use a lot of electricity.
  • Sit away from the TV and at least an arm’s length away from the computer screen and processing unit.
  • Decide to use a safety razor instead of an electric one.

New Report Warns of Health Risks from EMF, Radiation Exposure


BioInitiative 2012 Report

A new report by the BioInitiative Working Group 2012 says that evidence for risks to health has substantially increased since 2007 from electromagnetic fields (EMF) and wireless technologies (radio frequency – RF- radiation). The report reviews over 1,800 new scientific studies. Cell phone users, parents-to-be, young children and pregnant women are at particular risk.

This fifth BioInitiative 2012 Report was prepared by 29 independent scientists from 10 countries, holding medical degrees, PhDs, and MsC, MA or MPHs. The authors concluded: "There is now much more evidence of risks to health affecting billions of people worldwide. The status quo is not acceptable in light of the evidence for harm."

According to the report, everyone is exposed to two types of EMFs: 1. extremely low frequency electromagnetic fields (ELF) from, for example, electrical and electronic appliances and power lines and 2. radio frequency radiation (RF) from wireless devices such as cell phones and cordless phones, cellular antennas and towers, and broadcast transmission towers. Other sources of exposure include, electrical wiring, wireless handheld devices, cell towers, "smart meters", Wi-Fi, wireless laptops, wireless routers, baby monitors and other electronic devices.

Health topics include damage to DNA and genes, effects on memory, learning, behavior, attention, sleep disruption, cancer and neurological diseases like Alzheimer's disease. There appear to be risks for each of this from continued exposure.

The authors implore that new safety standards are urgently needed for protection against EMF and wireless exposures that now appear everywhere in daily life and specifically point out why the current standards are not adequate.

For example, "There is a consistent pattern of increased risk for glioma (a malignant brain tumor) and acoustic neuroma with use of mobile and cordless phones," says Lennart Hardell, MD, at Orebro University, Sweden. "Epidemiological evidence shows that RF should be classified as a human carcinogen. The existing FCC/IEE and ICNIRP public safety limits and reference levels are not adequate to protect public health."
A dozen new studies link cell phone radiation to sperm damage. Even a cell phone in the pocket or on a belt may harm sperm DNA, result in misshapen sperm, and impair fertility in men. Laptop computers with wireless internet connections can damage DNA in sperm.

Based on strong evidence for vulnerable biology in autism, EMF/RFR can plausibly increase autism risk and symptoms. "While we aggressively investigate the links between autism disorders and wireless technologies, we should minimize wireless and EMF exposures for people with autism disorders, children of all ages, people planning a baby, and during pregnancy," says Martha Herbert, MD, PhD.

Wireless devices such as phones and laptops used by pregnant women may alter brain development of the fetus. This has been linked in both animal and human studies to hyperactivity, learning and behavior problems.

According to David O. Carpenter, MD, co-editor, "The status quo is not acceptable in light of the evidence for harm."


The report is broken into 21 sections which clearly indicate the risks and include:
  • Statement of the problem
  • Existing Public Exposure Standards
  • Evidence of Inadequacy of the Standards
  • Evidence for Genotoxic Effects
  • Evidence for Effects on Immune Functions
  • Evidence for Effects on Neurology and Behavior
  • Evidence for Brain Tumors and Acoustic Neuromas
  • Evidence for Childhood Cancers
  • Evidence for Breast Cancer Promotion
  • Evidence for The Precautionary Principal
In 2012, the U.S. Government Accountability Office (GAO) called for a reassessment of exposure and testing requirements for mobile phones. The Environmental Working Group offers tips to limit exposure.
