Diary of Unknown Symptoms

Mystery of the Internal Vibration

Entry for February 15, 2006


I’m at my second day of googling the effects and symptoms of electromagnetic hypersensitivity. I come across an article written by Corky Adams in the Toronto Star. After reading the article my jaw dropped to the floor. I couldn’t believe what I was reading.

A study from Trent University had determined that Oshawa had the second highest levels of electromagnetic fields in a study of sixty communities.

Charting the hidden force at street corners

There’s a steadily growing conviction among some researchers that electromagnetic fields can promote bad things such as cancer, miscarriages, depression, Lou Gehrig’s disease and, possibly, Alzheimer’s disease. But there’s all-too-scanty knowledge of how much exposure people get in the course of a day.

To help bridge this knowledge gap, Magda Havas, who teaches in the Faculty of Environmental and Resource Studies at Trent University in Peterborough, has taken readings on the main streets of 60 Ontario communities ranging in size from Toronto (2.3 million people) to Burk’s Falls (1,000).

She found that 49 of the communities (82 per cent) had readings above the level that is associated with childhood leukemia. The worst of all the communities, by far, was Kingston, followed by Oshawa, London, Peterborough, and Toronto.

Burk’s Falls had the lowest readings, followed by Cambridge, Newmarket, Madoc, Perth and Bradford.

Pinpointing sources is important, because it is the accumulated exposure, collected at different places from different sources during the course of a day, that determines health impacts.

Havas is quick to point out there is no proof, as yet, that electromagnetic fields directly cause illnesses. But there is plenty of evidence showing they are associated with illnesses and can promote them.

Her work on Main Street, Ontario, should be a wake-up call to public utilities and other businesses generating electromagnetic fields, such as banks and cellphone companies, which one day could face lawsuits from people claiming compensation for impaired health.

No doubt aware of potential liability, the California Public Utilities Commission ordered a study eight years ago on the effects of electromagnetic fields. Slated to cost $11.2 million, it is the most extensive study ever done and is about to be released. According to the London Sunday Times, the study will suggest hundreds of thousands of people may be at risk.

The strength of magnetic fields is measured in milliGauss (mG), after the German mathematician Karl Friedrich Gauss (1777-1855). According to federal government guidelines in Canada, a cumulative, 24-hour exposure of up to 1,000 milliGauss is safe.

However, Havas says, this guideline is ridiculous. Studies have established that a 24-hour exposure in the range of 2-4 mG doubles the incidence of childhood leukemia. A daily exposure of 16 mG has been shown to triple the risk of miscarriage during the first 10 weeks of pregnancy. When breast cancer cells are exposed to 12 mG, their growth rate increases.

To put this in context, kitchen appliances, measured at a distance of 30 centimetres, can run from 0.1 to 30 mG. In offices, photocopy machines emit up to 4 mG, fluorescent lights up to 3 mG and computer terminals up to 0.6 mG. Power drills can generate up to 4 mG and power saws up to 30 mG.

In Kingston, Havas monitored 36 street corners on Princess St. between Division and Ontario Sts. Her mean reading was 47 mG. In Toronto, the mean reading for 108 street corners on Yonge St. between Bloor and Front Sts. was 19.2 mG. In Oshawa, the mean on Simcoe St. was 29.5 mG; in London on Dundas St., 22.9 mG; and in Peterborough on George St., 20.8 mG.

That’s not good news for sidewalk cafes, street vendors, couriers and people living over stores. Her study is published in The Science Of The Total Environment 298 (2002) at pages 183-206. The study is good news in terms of raising awareness and that’s crucial to any health issue.
