On August 24, 2010, Mr. Barrie Trower, a British physicist who was a microwave weapons expert and who worked for the Royal Navy and the British Secret Service, gave a talk at the University of Toronto about the health effects of WiFi and other forms of microwave radiation.

Mr. Trower came out of retirement because he was concerned that the microwave frequencies and intensities to which children are exposed in schools are similar to those used for microwave weapons.  He provided Dr. Havas with a copy of a talk he gave to the King of Botswana earlier this year (April 2010) and that document can be viewed here.

The talk at U of T was well attended with standing room only (well over 250 in the audience). There were 7 video cameras trained on Mr Trower while he spoke. His talk will be made available within the next couple of weeks.

After giving a presentation that lasted well over one hour, the questions continued for an additional hour showing the interest in this topic.

Mr. Trower received a standing ovation and applause broke out numerous times during this talk.

April 2010. When the students of Mountain View Elementary School in Ontario Canada started to complain about headaches in the classroom, a few mothers thought something must be wrong with the building because their children did not experience these symptoms at home.

After close examination of the school by concerned parents, they learned that a ultra high powered wireless WiFi system was installed to blanket the entire school to provide internet access.  The school’s computer classroom only contained 6 computers and the parents felt that it was simpler to provide a cabled system using ethernet connections, or a less powerful local WiFi system to service that one room and then shut it off when not in use – like a lightbulb is shut off to conserve energy.

Unlike cellphones – the dangers of WiFi come from the fact that it’s always on – pulsing away sending out microwave carrier signals 24 hours a day even is no one is online – and it’s not just coming from the schools transmitters situated on the ceilings.

Apple intends to market the iPad as a digital textbook reader and this portable wireless device is equipped with a very powerful WiFi transmitter – in this case you are holding the iPad WiFi transmitter in your hand and the microwave radiation is going right into your body.

APPLE  FACE TIME

We have all seen the new iPhone adds that show two people communicating via video over their phone.  This is only accomplished via the use of the iPhone’s built in WiFi. The cellular DATA connection is not fast enough for high quality video, but the WiFi feature of the phone will easily allow for video communication.  Once again – you are holding the WiFi transmitter in your hand.  You can now video-talk on the phone via WiFi.

The kids have learned that texting is safer than talking – but they have not considered that the WiFi pulse digital radiation is going directly into their hand. Now imagine a scenario where hundreds if not thousands of students are using their WiFi equipped iPhone or iPad with a connection to the schools high powered industrial grade WiFi system. All of the students and teachers will be bathed in a sea of pulsing microwave radiation – always on 24 hours a day. It’s not your average home setup.

The part that I find very unusual is that the school’s teachers and parents have tried to keep cell phone towers off of their properties and now the IT departments are bringing a similar microwave system right inside their school.  This is what some parents are worried about.

Several complaints and alternatives were presented to the school board by parents but these were met with deaf ears. The IT department had assured the trustees that there was no proof that WiFi caused any health effects and it was determined that the WiFi would remain turned on.

But the parents refused to accept that conclusion and pressed for action. Worried about the media campaign that was starting to unfold, the Simcoe County District School Board brought in Tony Muc, who was the Scientific Officer (Microwave) at Health Canada (Government Agency; Government Administration industry) from July 1971 — September 1975 (4 years 3 months) when the standards were being developed. He worked in the Radiation Protection Bureau – biological effects of microwaves; writing and revising regulations for microwave devices; surveys and research on health and safety.

He told the trustees –  ” I firmly believe that the science developed over the last 50 years… adequately supports the limits that are demonstrated in (Health Canada’s) Safety Code 6,” he said, referring to the section relating to electromagnetic fields (EMFs). Click Here to read news article.

“I’m going to continue to put my faith in science and I’m going to continue to use Wi-Fi. I’m going to continue to live in 2010,” said Innisfil trustee Donna Armstrong. “Wi-Fi is in that spectrum that the cells won’t be torn. It’s not fair for a body such as ours to make a scientific ruling. I’m relying on Health Canada.”

Robert Bradley, is the director of Health Canada’s consumer and clinical radiation protection bureau – and is also a member of the Canadian Wireless Telecommunications Association (CWTA) committee –  Bradley’s group provides research used in the publication of standards by Industry Canada.

But the concerned parents dug deeper and learned that the Toronto Star published a feature article addressing concerns from individuals that Robert Bradley is not acting in the public’s best interest when it comes to microwave radiation from wireless technologies.

WiFi uses microwaves and those limits are addressed by Canada’s Safety Code 6 standards that are based on the “thermal effect”, the limits where the heating of human tissues occur, which originated from naval military radar research over 40 years ago. Realizing that this new pulsed digital WiFi technology was developed after radar, and the WiFi limits are not based on human biological effects (the symptoms of radio-wave illness) that occur well below the current safety limits, the parents pressed on even further and brought their plight to the health officials in Ottawa that regulate Health Canada.

The parents also brought microwave specialist Barrie Trower to Canada to give a lecture at the University of Toronto to explain the dangers of microwave radiation such as Wifi. This generated an enormous amount of publicity for their cause on radio and TV and the story became front page news.

WHEN WILL THE PUBIC KNOW THE TRUTH?

Hearings were held in late April to re-examine Safety Code 6 limits and the outcome of these hearings will probably determine the fate of the students at Mountain View school and all children in Canada that attend schools that are blanketed by WiFi or WiMAX wireless technologies.

It’s just one more case where the wireless industry, the former electrical engineers who now regulate it and the IT technicians who refuse to even suggest or practice the precautionary principal – to err on the side of caution and install a safer, faster, secure and more reliable network using fiber optic technology proposed by Google and adopted by countries like Japan and Universities such as Lakehead in Thunder Bay Ontario.

It’s enlightening to see their determination to make a change in public policy but at the same time –  disheartening to realize that these parents need to go to this extreme to present their point to the school board.

July 28, 2010.  Researchers prove damage occurs in the mobility and DNA fragmentation of sperm if near the WiFi transmitter. 24/07/2010 | Romina Martoglio.  From Lavoz.com

Assumptions are well known that the electromagnetic waves radiated by cell phones, microwave ovens, computers and electrical appliances may cause adverse health effects. In fact, the World Health Organization (WHO) has formed a special division for researchers studying the effect of electromagnetic radiation.

As for the effect of these radiations on the reproduction of human beings, some scientific studies have suggested that electromagnetic waves generated by cell phones may affect sperm quality. On the other hand, it is proposed that the use of laptops (Laptop) could affect sperm production due to increased temperature in the testes to be used on the legs.

A group of researchers from Cordoba, members of Nascentis reproductive medicine center, decided to analyze the effect of laptops on the sperm, and concluded that the use of laptop mobility result in damage and fragment the DNA of these cells, to the point that might affect male reproductive capacity.

“We have found that exposure to the laptops connected to Wi-Fi, mobility decreases and increases the damage to the sperm DNA. Although these studies were performed in vitro, our results suggest it could be a cause of low fertility” says Conrado Avendaño.

While we need further research, our first advice is that people avoid using the laptop on your lap, ESPECIALLY if they are connected to Wi-Fi”, states Sánchez Sarmiento..

The direction of this research was provided by Conrado Avendaño, a biochemist specializing in Andrology. He was accompanied by a team of Ariela Mata, a specialist in Reproductive Biology and Chief of the Laboratory of Embryology, Cesar Sanchez Sarmiento, medical director, Andrew Juarez Villanueva, head of Gynecologic Endoscopy and Valeria Martinez, laboratory specializing in Andrology and Embryology.

For this study, they evaluated semen samples from healthy donors with no history of recent illnesses. Each sample was divided into two portions which were placed in separate rooms at a controlled temperature. One of the fractions was incubated near a laptop connected to the Internet via Wi-Fi, thus, to mimic the situation in which men place the machine on their legs.

“After four hours of incubation of sperm under two different conditions, we found that in the group exposed to the laptop, a large percentage of sperm was affected,” said Conrado Avendaño.

Results. There are three factors that were examined to study the sperm quality: if the sperm were alive, if they moved and if the sperm DNA was intact. “The study showed that exposure to these devices did not cause the death of sperm,” said Avendano.

Meanwhile, the analysis of mobility, it was found that in the group exposed to WiFi radiation, there was less sperm that are moving faster and an increase in the amount of stationary sperm.

“This is a sobering if you take into account that the sperm are moving progressively to finally be able to reach the egg and fertilize it, and then form an embryo,” said César Sánchez Sarmiento.

Finally in terms of sperm DNA integrity, was found through a study known as “Tunnel”, which both groups of spermatozoa had a significant difference. “In the fraction exposed to radiation had a significant increase in sperm with fragmented DNA (broken),” said Avendano. Sánchez Sarmiento argues that the importance of this aspect is that reproductive medicine has proven that “one of the causes of changes in fertilization and embryonic development is therefore the break in the DNA molecules of the sperm.”

July 22, 2010:  Peterborough Examiner. Adding light to heat of WiFi debate.

Are microwaves, emitted by WiFi and mobile phones, safe? Why is this question so controversial and why can’t scientist agree on the answer?

Let’s take a closer look at the WiFi debate. Microwave radiation was first used for radar

during the Second World War and exposure was restricted to military personnel. The original guidelines were based on the ability of a 70 kilogram male to dissipate heat. The effects of microwave exposure -cataracts, reduced sperm viability, headaches, and tinnitus -were assumed to be due to heating.

Today we use microwaves to talk to and text our friends (mobile phones) and to share data (WiFi). We are all exposed, including young children who are the most vulnerable among us. Canada’s guidelines are still based on a heating effect despite numerous scientific studies documenting adverse effects that are non-thermal and potentially life threatening.

So the WiFi debate hinges on the question, “Is heating the only adverse effect of microwave exposure?”

The current heat-based Health Canada guideline for microwaves is 1,000 microWatts/cm2. Levels of microwave radiation are unlikely to exceed that guideline in most Canadian environments and so we have nothing to worry about. Right? Wrong!

Let’s take a look at the other side of the debate.

Some countries have much lower guidelines than Canada. The guidelines in Russia and in Salzburg, Austria are 1% and 0.01% (respectively) of our federal guidelines. These countries do not follow the U.S. military assumption from the 1950s that, “damage associated with heating is the only possible effect of microwave radiation.”

Scientific studies document biological and health effects well below the thermal guideline at levels to which we are currently exposed in the classroom and in our homes and offices.

These effects include difficulty sleeping, fatigue, chronic pain, skin problems, difficulty concentrating, poor short-term memory, dizziness, nausea, tinnitus, depression, anxiety, irritability as well as cancers and reproductive problems..

Even Health Canada (Safety Code 6 1999) acknowledges that sensitivity to radiation varies and that, “Certain members of the general public may be more susceptible to harm from RF [radio frequency] and microwave exposure.”

During the past 10 years various countries and institutions (including Toronto Public Health) have issued warnings about the use of cell phones (which are still more prevalent than WiFi) and scientists and medical doctors worldwide have signed at least 10 Resolutions and Appeals, asking that regulatory agencies revise their guidelines downward to take into account the non-thermal effects of this radiation.

It takes time for policy to catch up to the science, especially when maintaining the status quo has financial benefits for both the government and for the multi-billion dollar wireless industry. We knew that cigarette smoking was unhealthy back in the 1950s but it took several decades to develop the political will to acknowledge this and limit smoking in public places.

The same is happening with microwave radiation. The user of the technology has the greatest exposure but those who are near the antennas that communicate with WiFi computers or with mobile phones are exposed to “second hand radiation” that is also dangerous.

Do we really want to risk the health of students and teachers for the convenience of wireless technology when wired technology does the same job without microwave exposure?

I, for one, would like to err on the side of caution, especially in schools where the health of children is at stake.

February 2010. Lakehead University hosted a public lecture during their ‘Research and Innovation Week’ and invited Drs. Henry Lai (University of Washington), David Fancy (Brock University) and Magda Havas (Trent University) to address the Thunder Bay audience about wireless exposure and the possible health effects. Read what Thunder Bay News Watch has to say about the event.

Dr. Lai spoke about the “Biological effects of non-ionizing electromagnetic fields” and mentioned studies showing genetic and molecular effects, changes in the blood brain barrier, changes in calcium flux. He said electromagnetic energy can affect the nervous system, the cardiovascular system, the immune system, as well as hormones and reproduction, and it can generate behavioural changes and subjective symptoms. He showed that radio frequency radiation induces oxidative stress in cells by way of the Fenton Reaction that involves iron, hydrogen peroxide and the production of hydroxy free radicals leading to cellular damage. The free radicals can lead to functional changes, cell death, or cancer. These are some of the mechanisms leading to the symptoms described in the literature.

Drs. Lai and Singh were the first to show DNA damage in rats exposed to cell phone radiation. The comet assay is one of the most sensitive tests that shows fragmentation of DNA. The fragments resemble a comet and hence the name.

At least 60 peer-reviewed papers report biological effects at very low intensities of radio frequency radiation but these are all of short exposure. Long-term exposure data are scarce. What these long-term studies show are the following:
1. effects differ based on exposure duration.
2. some effects occur only after either prolonged or repeated exposure but not after short-term exposure.
3. some effects disappear after prolonged or repeated exposure (due to habituation).
4. an organism becomes more sensitive after repeated exposure.

Dr. Lai reviewed the scientific literature dealing with the biological effects of cell phone radiation. He found that results were dependent on source of funding. Sixty-seven percent (67%) of the non-industry funded studies showed an effect of cell phone radiation while only (28%) of the studies funded by industry reported similar results. Huss et al. 2007 came to the same conclusion and stated that “The interpretation of the results from existing and future studies of the health effects of [radio frequency] radiation should take sponsorship into account.”

Dr. David Fancy spoke about “Electrosensitivity: a first person perspective”. Dr. Fancy’s sensitivity lead him on a journey that took him through periods of great illness to good health. He now provides information to those with sensitivity on how to cope and how to recover their health. David Fancy is an inspiration to those who suffer from electrohypersensitivity because he found a way, not only, to desensitize his body but also to improve his health. Dr. Fancy comments on the role of the WHO and other government agencies regarding EHS. Click here to down load his presentation as a pdf.

Dr. Magda Havas spoke about “Electrosmog and Electrosensitivity” and presentation some of her studies showing how radio frequency radiation can affect the heart (rapid or irregular heart rate) and the blood (rouleaux formation blood cell stick together like a stack of coins); how exposure to compact fluorescent lighting can cause skin rashes; and how dirty electricity may conribute to higher blood sugar among diabetics and tremors among those with multiple sclerosis.

Based on an estimate of 3% of the population with severe sensitivity and another 35% with moderate to mild sensitivity, as many as 1 million people in Canada may be severely affected by electrosmog and another 12 million may have mild to moderate symptoms when exposed to this type of radiation. If these values are even close to the real values, we have an emerging human health crisis that is escalenting according to Hallberg and Oberfeld (2006), who state that the prevalence of electrohypersenstivity (based on self-diagnosis) may reach 50% of the population by 2017.

While not all students at Lakehead are pleased with the decision to limit WiFi on campus (yes limit as some places, like the student pub, are allowed to have WiFi), students at other institutions would welcome studying in a wireless-free zone. Dr. Havas quoted from an email sent to her in November 2009 from a student at Carleton College in Northfield Minnesota who experiences seizures on campus after extended exposure to WiFi. He would like to know how to convince his college to remove WiFi.

The organizers of this event invited industry representatives, scientists affiliated with other universities who hold different views on this subject, as well as scientists from Health Canada to give presentations but all invitations were declined. Why are these people unwilling to appear in public to present their perspective on this issue? How can we have an open debate if one side is not willing to participate. Isn’t this what we value about democracy and isn’t this one of the important roles of a university to provide a forum for free and open discussions about things that matter?

Dr. Fred Gilbert, President of Lakehead University, has taken an unpopular stance regarding wireless technology because he does not think it is as safe as some would like us to believe. He has provided fibre optic connections in place of wireless routers for student and staff access to the internet. The National Library in France has done the same thing.

Interestingly, fibre optics provide much faster and more secure service than wireless and may very well be the ideal form of interconnectivity in places where there is a high volume of traffic and where security and speed are important. See Google offers alternative to WiMax. Fibre optics also has the advantage of not contributing to electrosmog and not making people ill. Here we have an example where the best technical solution (fibre optics) is also the best for our health. It doesn’t get better than this.

February 2010. Google is planning to launch an experiment that we hope will make internet access safer, better, and faster for everyone. They plan to test ultra-high speed broadband networks in one or more trial locations across the country. Their networks will deliver Internet speeds more than 100 times faster than what most Americans have access to today, over 1 gigabit per second, fiber-to-the-home connections. They’ll offer service at a competitive price to at least 50,000 and potentially up to 500,000 people.

From now until March 26th, they are asking interested municipalities to provide them with information about their communities through a Request for information (RFI), which they will use to determine where to build their network.

If you are a school IT administrator or community and are thinking of going WIFI – think again – Fibre Optics are the best way to go. Do it once and do it right and perhaps Google can give you a helping hand. Click here to learn more.

To: Open letter to Librarians, Library Administrators and Visitors to Libraries.

From: Dr. Magda Havas, BSc, PhD, Trent University, Peterborough, Canada.

ALERT: WiFi Hotspots in Libraries may be Harming Staff and Visitors and may Prevent Access to those with Medical Implants.

While a growing number of libraries are installing WiFi hotspots for their visitors and staff, they seem not to be reading the literature on this topic related to health effects, interference with medical implants, speed of data transmission, and data security issues.

WiFi uses a microwave frequency of 2.45 GHz. This is the same frequency used in many mobile phones (cell and cordless) and these microwave frequencies have been linked to various illnesses including cancer, reproductive problems, chronic fatigue, chronic pain, skin disorders, sleep disorders, cognitive dysfunction, tinnitus, dizziness, nausea, etc. That is one reason why the France National Library (BNF) decided to give up WiFi in 2008.

Based on reports of genetic alternations in human cells at WiFi frequencies (a study conducted at the University of Chicago, Department of Medicine by Lee et al. 2005) and on an increasing number of scientific reports documenting ill effects of microwave exposure (including The Bioinitiative Report) the safer route is to provide wired rather than wireless access to the internet.

While it might take years of exposure to develop cancer (as has been shown in mobile phone studies) changes in gene expression occurred within a matter of a few hours for cultured human cells under controlled laboratory conditions. Lee and colleagues noticed that 221 genes altered their expression after a 2-hour exposure and 759 genes after a 6-hour exposure at levels below thermal effects, on which guidelines are based. If it doesn’t heat your tissue it is assumed to be safe, according to federal guidelines in many countries. However, scientific studies are showing that this ‘thermal effect assumption’ is no longer valid.

Another consideration is that some people with medical implants may be adversely affected because of radio frequency interference (RFI) and may not be able to visit libraries unless the WiFi service is turned off during their stay. This violates the Americans with Disabilities Act and similar acts in other jurisdictions.

Dr. Gary Olhoeft, Professor of Geophysics at the Colorado School of Mines, brought this to my attention last November at a presentation he gave in Golden Colorado organized by the EMR Policy Institute. Not only is he an expert when it comes to electromagnetic interference (EMI) but he is also one of 20 million Americans who has a medical implant. In his case the implant is a deep brain stimulator to control tremors due to Parkinson’s Disease. Malfunctions of deep brain stimulators may constitute a medical emergency and can be fatal. According to Dr. Olhoeft, interference may prevent normal therapeutic function, reset or reprogram the device, bring damaging energy into the device or body, and cause injury including death.

Medical implants include cardiac pacemakers/defibrillators, neurostimulators, infusion pumps for diabetics, artificial hearts, metal rods to support broken bones, spinal stimulators, and hearing aids.

In addition to WiFi there are a growing number of devices that can cause electromagnetic interference (EMI) including: cell phones, CB or ham radios, TV and radio transmitting antennas, theft detectors and security gates (airports, schools, stores, libraries), power lines, electric arc welding equipment, electricity substations and generators, cardiac defibrillators, diathermy equipment and MRI (magnetic Resonance Imaging).

The France National Library replaced WiFi not only because of health concerns but because wired service can handle a larger volume of data transmission more rapidly, something that is essential for a large library with many researchers, and because it is a more secure and reliable way of transmitting data. The France National Library is not the first and will not be the last replacing WiFi terminals with wired terminals.

The purpose of this open letter is to alert libraries considering WiFi to investigate the feasibility of using wired terminals and for those libraries with WiFi to consider replacing them with wired service. Ignoring these issues of interference with medical devices and potential health effects will not make the problems go away.

As Aldous Huxley said, “Facts don’t cease to exist just because they are ignored.”

From: Dr. Magda Havas, B.Sc., Ph.D., Trent University, Peterborough, Canada.

Re: ALERT: Wireless routers in schools may be harming students and staff

Very little research has been published on the health effects associated with wireless routers used in schools and on the effects of cell phones on children. Studies have focused entirely on adults and these studies are showing an increased risk of several types of tumors, including tumors of the brain, the eye, the nerve leading to the ear, and the salivary gland with mobile phone use. These tumors appear on the same side of the head used to listen to the cell phone and appear after 10 years of moderate to heavy cell phone use. One of the most recent studies by Hardell and colleagues (2009) reported that the highest risk was for those who started using a mobile phone before the age of 20.

Other studies are finding an increased cancer rate for those who live within 300 to 400 meters of cell phone antennas. The cancer rates are higher and the cancers grow more rapidly than in populations further from these antennas.

This is particularly disturbing for the following reasons:

1. Younger children are beginning to use cell phones and they are much more sensitive to this radiation than adults.

2. Tumors are developing in adults at a much faster rate than expected with cell phone use and this is likely to be even faster for children whose cells are dividing.

3. A growing number of schools are installing wireless routers for internet access. The same frequencies are used for wireless routers in schools as are used for mobile phones (cell and cordless phones). These frequencies are between 2.4 and 6 GHz in North America. Consequently children are receiving a double dose of microwave radiation from both wireless routers and mobile phones.

4. Some of these children may be exposed to wireless routers at home as well and they may be living near cell phone antennas giving them around the clock microwave exposure.

Studies also are documenting reproductive problems for men who use cell phones. There is a decrease in sperm density, motility, and viability. While sperms are produced every few months, females are born with all of their egg cells and are much more vulnerable to damage as a result. To date there have been no studies on the effects of microwave radiation from mobile phones and wireless computers on egg cells and reproductive success in women.

The purpose of this open letter is to alert those who are responsible for the health and safety of children to think twice before installing wireless microwave technology in schools and exposing students and staff to radiation that could be potentially harmful.’

December 2009. If you are a student who is sensitive to electromagnetic energy or who does not want to be unnecessarily exposed to microwave radiation then this is definitely one university you should consider attending.

Lakehead University has opted for a fibre-optic network rather than a wireless network to provide access to the internet for students attending the campus in both Thunder Bay and Orillia, Ontario, Canada.

This is the first university in North America that has opted for the precautionary principle and that places the health and safety of students and staff above the convenience of wireless technology. Despite this policy students have access to the world wide web and have adequate cell phone access as well. What they don’t have is unnecessary exposure to microwave radiation.

We look to universities to provide leadership in society and this is one university that does just that. Despite lucrative, multi-year contracts offered to universities by cell phone providers for erecting cellular antennas on campus property, Lakehead has refused to place their students and staff at risk. In their policy report, effective November 10, 2009, they state “Cellular communications antennae will not be placed on University Property.”

If you study or work on a university campus and if you have wireless access or see antennas on campus property, ask your administrators to guarantee the safety of these installations in writing. If they refuse, then these installations should be removed and replaced with a fibre-optic network that will be faster, more secure, and safer than wireless. If your university won’t allow asbestos insulation to be used then they shouldn’t allow wireless technology to proliferate either because both are harmful to human health.

Open Letter to Parents, Teachers, School Boards Regarding Wi-Fi Networks in Schools and Cell Phone Antennas near Schools

by Magda Havas, 2009

It is cheaper but is it safer?

More and more schools are providing internet access in schools but, instead of going to a wired system, they are opting for the less expensive wireless networks, which generate microwave radiation.

Is this exposure to microwave radiation safe and should children be exposed? What are the immediate and long-term biological and health effects and where are the studies documenting the safety of this exposure?

After decades of research that established the harmful effects of asbestos,school boards are having it removed from school buildings at considerable cost. Will wireless internet and cell phone antennas on school property experience the same fate? Read the open letter and decide for yourself. Click here for pdf.
