Turn off the breaker to the room, use candles and use wind up clocks!

Thanks!!
Please do not take this wrong, but I have been involved in numerous EMF investigations both commercial and residential, most commercial were because some equipment did not function properly particular old CRT monitors when exposed to high levels of EMF. 99.9% of the residential EMF investigations I have done the homeowner was just a tad nuts to down right freaking fruit cakes.

But they paid me and in SOME cases I was able to resolve the issue other cases I referred to a firm we work with that builds shields.

Can I add my voice to this without offending?
We live in a time when all manner of facts are in dispute and called false.
I have studied and practised electrical engineering for 35 years now, and I think that a fair bit of what I call knowledge of this field is able to be verified.
Here is my take on the EMI from power lines and their effect on health:
  1. Some studies have shown some negative health effects from power line fields. Many others, however, have found no such link,
  2. As far as we can tell, low-frequency fields do not cause chemical changes, they simply do not have enough energy to do this.
  3. As far as has been observed, exposure to very high levels of electromagnetic fields, such as might be experienced during a routine CT scan in your nearest hospital, does not lead to negative health outcomes.
I could elaborate, but the bottom line is that I do not think that anyone has anything to worry about from electric power lines and their electromagnetic fields.
Just my take on this, mind. I might be mistaken.
Comments, anyone?

BUT In the face some all the stories that were coming out year ago when I built my house (I built 3) I wired them in a "EMF" friendly manner. I figured err on the side of MAYBE and when the houses were going to be sold it MIGHT be a selling point.

Made no difference, 1st house sold to a single guy that could care less, 2nd house was taken by the county eminent domain and 3rd I lost to the ex.

Just adding that most of those studies that I saw that did see any negative effects were along high tension distribution lines. Don't forget that they don't use a neutral, but instead multiple sets of 3 phase wiring. Extremely high voltage and current.....

The question now is, was the results of those findings because of:
* the weak rotating magnetic fields;
* or the sometimes significant leakage current through ground;
* or the fact that these neighborhoods are typically the poorest, as the lines tend to lower property values?

All are usually ignored in such studies. I've always been sceptical of studies before I read them. Statistics is just math, how you apply it requires quite a brains of said topic.

Otherwise your post was well written.

Cheers!

No, you cannot. These days people tend to be either on one side of an issue or the other. There are very few who take a neutral position and are open to weigh the facts from both sides and then form an opinion based on those facts. If you promote your position, you have already offended everybody who is of the other opinion.

Here on Long Island there was a group who demanded the government investigate what they called "cancer clusters." Their position was there was some outside or artificial reason, be it pollution, power lines, or whatever, causing an unusually high number of cancer cases in particular areas.

They showed a map of Long Island and mapped out where people had cancer or died from cancer, and a casual look did indeed show that the cases were clustered in some specific locations. (No idea how they got the addresses of people who had cancer.)

After doing tests like air quality, soil samples, groundwater samples, EMF samples there were no answers and nothing pointed to the reason. Until a State official pointed out by demonstration that randomness does not mean that when you throw 100 marbles on a map that they each go their separate ways and evenly distribute themselves all over the map. Some end up here and there, but others tend to "cluster."

Further analysis showed that many of the clusters were simply high intensity neighborhoods where the lots were only 1/8 acre, and therefore the people were clustered and there was a much higher population per sq.mile, and there was little clustering in neighborhoods with 1 acre or 2 acre zoning where there were simply fewer people per sq.mile. But the incident of cancer per 100 people was the same.

So until someone came up with a reasonable explanation, the cancer cluster activists thought their theory was bulletproof, nobody could convince them otherwise, and anybody who would dismiss their theory was an enemy. (Many of them were convinced polluted groundwater was the cause therefore past industry was to blame and there would be a lot of $$$ to recoup)

We also live in a time that people dismiss any fact that doesn't cater to their preconceived ideas.

Re: Is aluminum tape around power cables for EMF reduction unsafe?


Totally anecdotal, but I grew up in a house that backed onto 3 x 2 circuit 115kv distribution lines. spent a better part of my youth playing under them - we had the biggest backyard in the world. All good so far (65), same with my brother, dad lived to a ripe old age.

Part of the problem with 'city-folk' up here is they want all the modern conveniences but don't want any generator sites near them and howl like hell if the utility tries to increase line capacity.

I lived in Loudoun county VA, at one time the fastest growing county in America. When I moved there it was rural and population around 52,000, the population now exceeds 260,000 a few years back DOMINION POWER wanted to install new 115kv lines along their right away. The screaming and crying from all the newbies was heard state wide, My stance was you move here want AC and heat, most of the new houses have heat pumps and electric backup, not to mention lights.

They lost in court, the final karma was the guy that lead the battle ended up with a substation in his back yard.

Not a total loss. The sub-station is certified non-GMO and gluten-free.

Thanks for all the input, both the informative and the amusing.

FWIW I'm removing the tape as we speak...

Thanks!!

Re: Is aluminum tape around power cables for EMF reduction unsafe?


In the OP, you mentioned that you painted the ceiling with Y-Shield (emf shielding) paint. Without arguing the efficacy of shielding paint, I find it curious that you would only paint the ceiling to shield cellular phone signals. Cel signals are emitted from relative low-height towers that generally radiate outwards. In fact, most sources of emf are emitted from close proximity to the earth's surface. Shielding the ceiling would only provide a barrier from emissions from satellites, aircraft, etc.
