Open Letter to Parents, Teachers, School Boards. Regarding Wi-Fi Networks in Schools - May 5, 2009
by Dr. Magda Havas, Associate Professor, Trent UniversityI am a scientist who does research on the health effects of electromagnetic radiation and I am becoming increasingly concerned that a growing number of schools are installing Wi-Fi networks and are making their school grounds available for cell phone antennas.
You will be told by both the federal government (Health Canada and Industry Canada) as well as by the Wi-Fi provider that this technology is safe provided that exposures to radio frequency radiation remain below federal guidelines.
This information is outdated and incorrect based on the growing number of scientific publications that are reporting adverse health and biological effects below our Safety Code 6 guidelines (see www.bioiniative.org) and the growing number of scientific and medical organizations that are asking for stricter guidelines to be enforced.
For these reasons, it is irresponsible to introduce Wi-Fi microwave radiation into a school environment where young children spend hours each day.
FACT:
1. GUIDELINES
Guidelines for microwave radiation (which is what is used in Wi-Fi) range 5 orders of magnitude in countries around the world. The lowest guidelines are in Salzburg, Austria, and now in Liechtenstein. The guideline in these countries is 0.1microW/cm2. See short video (
http://videos.nextup.org/SfTv/Liechtenstein/AdoptsTh...). In Switzerland, the guideline is 1 and in Canada it is 1,000 microW/cm2! Why does Canada have guidelines that are so much higher than other countries?
Canada's guidelines are based on a short-term (6-minute) heating effect. It is assumed that if this radiation does not heat your tissue it is "safe." This is not correct. Effects are documented at levels well below those that are able to heat body tissue (Analysis of Health and Environmental Effects of Proposed San Francisco Earthlink Wi-Fi Network, 2007). These biological effects include increased permeability of the blood brain barrier, increased calcium flux, increase in cancer and DNA breaks, induced stress proteins, and nerve damage. Exposure to this energy is associated with altered white blood cells in school children; childhood leukemia; impaired motor function, reaction time, and memory; headaches, dizziness, fatigue, weakness, and insomnia.
2. ELECTRO-HYPER-SENSITIVITY
A growing population is adversely affected by these electromagnetic frequencies. The illness is referred to as "electro-hyper-sensitivity" (EHS) and is recognized as a disability in Sweden. The World Health Organization defines EHS as: ". . . a phenomenon where individuals experience adverse health effects while using or being in the vicinity of devices emanating electric, magnetic, or electromagnetic fields (EMFs). . . EHS is a real and sometimes a debilitating problem for the affected persons, while the level of EMF in their neighborhood is no greater than is encountered in normal living environments. Their exposures are generally several orders of magnitude under the limits in internationally accepted standards."
Health Canada acknowledges in their Safety Code 6 guideline that some people are more sensitive to this form of energy, but they have yet to address this by revising their guidelines. Symptoms of EHS include sleep disturbance, fatigue, pain, nausea, skin disorders, problems with eyes and ears (tinnitus), dizziness, etc. It is estimated that 3% of the population are severely affected and another 35% have moderate symptoms. Prolonged exposure may be related to sensitivity and for this reason it is imperative that children's exposure to microwave radiation (Wi-Fi and mobile phones) be minimized as much as possible.
3. CHILDREN'S SENSITIVITY
Children are more sensitive to environmental contaminants and that includes microwave radiation. The Stewart Report (2000) recommended that children not use cell phones except for emergencies. The cell phone exposes your head to microwave radiation. A wireless computer (Wi-Fi) exposes your entire upper body and if you have the computer on your lap it exposes your reproductive organs as well. Certainly this is not desirable, especially for younger children and teenagers. For this reason we need to discourage the use of wireless technology by children, especially in elementary schools. That does not mean that students cannot go on the Internet. It simply means that access to the Internet needs to be through wires rather than through the air (wireless, Wi-Fi).
4. REMOVAL OF WI-FI
Most people do not want to live near either cell phone antennas or Wi-Fi antennas because of health concerns. Yet when Wi-Fi (wireless routers) are used inside buildings it is similar to the antenna being inside the building rather than outside and is potentially much worse with respect to exposure since you are closer to the source of emission.
Libraries in France are removing Wi-Fi because of concern from both the scientific community and their employees and patrons. The Vancouver School Board (VSB) passed a resolution in January 2005 that prohibits construction of cellular antennas within 1000 feet (305 m) from school property. Palm Beach, Florida, Los Angeles, California, and New Zealand have all prohibited cell phone base stations and antennas near schools due to safety concerns. The decision not to place cell antennas near schools is based on the likelihood that children are more susceptible to this form of radiation. Clearly if we do not want antennas "near" schools", we certainly do not want antennas "inside" schools! The safest route is to have wired internet access rather than wireless. While this is the more costly alternative in the short-term it is the least costly alternative in the long run if we factor in the cost of ill health of both teachers and students.
5. ADVISORIES
Advisories to limit cell phone use have been issued by the various countries and organizations including the UK (2000), Germany (2007), France, Russia, India, Belgium (2008) as well as the Toronto Board of Health (July 2008) and the Pittsburgh Cancer Institute (July 2008). While these advisories relate to cell phone use, they apply to Wi-Fi exposure as well since both use microwave radiation. If anything, Wi-Fi computers expose more of the body to this radiation than do cell phones.
6. PRECAUTIONARY PRINCIPLE
Even those who do not "accept" the science showing adverse biological effects of microwave exposure should recognize the need to be careful with the health of children. For this reason, we have the Precautionary Principle, which states: In order to protect the environment, the precautionary approach shall be widely applied by States according to their capability. Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost effective measures to prevent environmental degradation. In this case "States" refers to the School Board and those who make decisions about the health of children.
The two most important environments in a child's life are the home (especially the bedroom) and the school. For this reason it is imperative that these environments remain as safe as possible. If we are to err, please let us err on the side of caution.

Macular Degeneration Prevention
by Brenda Gill, NDThe macula is a portion of the retina in the back of the eye that is responsible for fine vision. Degeneration of the macula is the leading cause of severe visual loss in persons 55 years or older. This is a result of free radical damage similar to the type of damage that induces cataracts. The risk factors include aging, smoking atherosclerosis and hypertension.
Nutrients and herbs that may be helpful are:
Anthocyanidins - These are constituents that act as antioxidants. The strongest are found in bilberry extracts and ginkgo biloba. These plant extracts are more potent in their antioxidant and free radical scavenging activity than any other nutritional antioxidant. They also are more specific to the eye. Bilberry is also used for poor day and night vision, glaucoma and diabetic retinopathy. It also reinforces the collagen structures of the retina. Ginkgo is also used for insufficient blood flow to the brain. It helps prevent lack of oxygen and free radical damage to the retina and macula.
Vitamin C/vitamin E/selenium/zinc/beta-carotene are all antioxidants. Therefore, these are all important to have in the diet or as a supplement to minimize damage to the eye by free-radicals.
Lutein - This is another specific antioxidant, a type of carotenoid. These are found in high concentrations in kale, spinach and chard. They are also specific to the eye ad protect the retina from damage, especially from sunlight.
Foods - Avoid rancid foods and other sources of free radicals, such as deep fried foods. Increase legumes such as pinto, black, kidney, aduki and mung beans. These are high in sulphur-containing amino acids that decrease damage. Also, include veggies rich in carotenoids such as yellow veggies/red peppers/carrots. Of course, flavinoid-rich berries, such as cherries,blueberries, blackberries, raspberries and strawberries, are important to have as part of your food intake.
Water - As always, make sure you are flushing those free radicals through the system with 1/2 your body weight in ounces of water.
