timberland chocorua trail Couple adds Faraday cage to reduce electromagnetic fields
When patients leave family physician Rohini Kanniganti’s office in Boulder, they receive a high five. The invisible fields occur naturally as the result of the Earth’s magnetic pull, and are created in abundance from electric devices and pathways. But Michael Dubson, a senior instructor in the CU physics department says, “(Low frequency electromagnetic radiation) is harmless unless the intensity is so high that you begin to start heating. But there’s no chance that kind of radiation can cause cancer. There’s no evidence of that.”Cancer wasn’t Kanniganti and Plinke’s concern, though.”For us it was just a quality of sleep issue,” says Plinke, an environmental engineer. “I didn’t want to inundate our sleep with a lot of electromagnetic fields because it would just energize the brain. At least that made sense to me.”The Faraday cage was discovered by 19th century Michael Faraday. A Faraday cage essentially blocks external electrical fields from an enclosed space. It’s the same principle that keeps passengers safe from lightning strikes when they are in an automobile. The wire mesh was laid in the cement like flooring material, too. Most of the house is a cell phone dead zone. It’s not a bad thing, Plinke discovered, at least according to friends with chatty children.”A lot of parents have said, ‘Just for that purpose alone, it’s worth doing this,'” Plinke says. “‘If my daughter wasn’t locking herself in her room and talking to her friends forever (on a cell phone), I would pay any money.’ I just had to laugh.”Visitors to the home a warm, inviting dwelling with rounded walls, painted with earth tones and bathed in light have called it a quiet space, Plinke says. It’s not without noise the couple’s two children, Sitha, 6, and Roan, 4, often fill the home with laughter and loud noises children make. A plaque bearing the words “Ahimsa Platz” adorns the entryway. “Whenever I come back and sleep here, I wake up in the morning and think, ‘That was a good night’s sleep.'”But I’m a scientist, too. It’s anecdotal evidence. Who knows what is real and what is not real? It’s real to me anyway.”Kanniganti, too, says it’s difficult to test how vastly reduced electromagnetic fields in their home may or may not affect the family. At some point, though,
it’s not about empirical evidence; it’s about enjoying the experiment.”You have to take an evidence based approach, but even in the lack of evidence, you go for the quality of life,” she says.

Who knows what is real and what is not real? It’s real to me anyway.”6/2/2009 9:39:47 AMIt’s not Voodoo science. Just because you can’t see, smell, or hear it, doesn’t mean that it’s not capable of causing harm. 100 years ago, no one understood the harmful effects of radon gas but now we mitigate our homes against it regularly. When you sleep, your body produces melatonin, a hormone that your body uses to fight cancer. If you are regularly exposed to a high EMF (electro magnetic field) while asleep, your body will produce diminished amounts of melatonin and you are more susceptible to cancer as a result. This is particularly true for children. I believe that lowering EMF in the home will become more and more common in the future. Personally, I don’t believe that our bodies were designed to be exposed to high levels of EMF for long periods of time. While life without electricity would be next to impossible, there are steps that people can take to lower their home EMF if they are educated. The big power companies do not want people to know about this because it would cause them to have to spend millions of dollars moving power lines away from peoples’ homes. Let’s see what the science journals say in a few more years. In the meantime, I am happy that I have already taken steps to lower my home’s EMF as much as possible.6/2/2009 11:00:39 AMNo shielding for neutrons, cosmic rays, gravity pulses? I can’t believe this man is willing to live in such a death trap.6/2/2009 11:07:57 AM Thanks for the classic “But 100 years we did not know.”What we do know today, is that life expectancy is higher than ever. Except in third world places which have fewer cell phones, m’wave ovens etc. I was under the impression that EMFs attenuate at the square or cube of the distance from the source, so basically any EMF source more than a few feet away has to be high tension line powerful to have any effect. A nightly trip to the circuit breaker box to flip off the switch to their bedroom would do that far more effectively than a Faraday cage, assuming their heads aren’t adjacent to a wall of another room that has live wiring on another circuit. (I suspect the bulk of the relaxation effect they’re feeling is a result of the great sound and vibration insulation they now have, with double drywall everywhere, but I’m well known as a skeptical crank.) It’s interesting, and perhaps telling, that the only paragraph that describes electromagnetic /radiation/, rather than electromagnetic fields,
is the one that quotes the CU physics instructor. The two phrases describe the identical physical thing.
