Living under/near the transmission line (150 kV line)

Dear friends, I've some questions here.
1. If we live under/near 150 kV transmission line, will it give us negative effect for our health?
2. How much the safe value of Electric Fields and Magnetic Fields so that they would not give us negative effect
3. How far is the safe distance (minimum distance) from our house to the 150 kV transmission line so that the 150 kV line would not give negative effect to our health?
Thanks for your attention

Mercury rectifier. Doesn't that say it all?

Those older rectifiers were not hermetically sealed but had ion pumps to keep vacuum. Any idea where the fumes went?

QB,

The fact that BC Hydro bought some houses doesn't prove anything regarding EMF hazards.

This anecdotal "evidence" is not meaningful data. Some people get sick and die, others live to be 100. Humans are hard-wired to look for patterns and correlations. That helped keep our ancestors alive. But a lot of these correlations are meaningless.

To Skogsgurra:

No problems of being funny or even greedy. It is a free world. Take your pick QB is a stupid or a stubborn guy. No problems.

I just offered my two cents here and some real cases that I have no answers. I wish I should have done another Ph.D on the potential impacst between cancer and power system EMF. However, that will require me to start in a Medical school first.

 
Perhaps I wasn't clear enough. Mercury rectifiers work with a pool of mercury and a rarefied atmosphere in which the arcs burn.

Mercury (Hg) is very bad to animals and especially bad for reproduction organs.

I didn't mean to say you were either stupid or stubborn. All I wanted to point out is that if a young female person works in a mercury polluted environment, the first thing to suspect isn't the electric or magnetic field for which no correlation with reproduction deficiencies is known.

Isn't the proven bad effect on reproduction a much more plausible explanation?

Hi Gunnar Englund
Thanks for telling me that "Mercury (Hg) is very bad to animals and especially bad for reproduction organs."

Hi David:
NC Hydro can not prove anyting either. In a word some people believe something and other don't
 
just make sure your house is outside of the fall zone of the transmission line/pole/tower. . .

that is the only factual answer as to the risk of living near such rights of ways!
 
I found out that the grass within the wind farms were shorter than the grass outside. I could not tell the reasons from electrical aspects or maybe the wind farms I have been to are special cases because the soil under that two wind farms are just not as good as the these of the other parts.They are in different locations. people always say wind farms is the most clean energy in the world now.
More Occam’s razor type discourse here. I too have been to MANY wind farms, and your observation is not without basis. But I came to a totally different, and in my opinion, more plausible explanation. Raptors, a major natural check and balance to rodent overpopulation, get killed in very high numbers by rotating windmill blades, especially the 3 blade smaller varieties. With fewer surviving raptors, the rodents eat more of the grasses, not just the seeds, as their population explodes rapidly. My conclusion was formed by seeing countless little field mice and prairie dogs scurrying around everywhere I walked. If EM fields were affecting the grass length, shouldn’t it have been affecting the rodents too? If not first? Same base observation, different conclusion based on evidence at hand, not pre-conceived ideas. Like the mercury rectifiers, a much more likely explanation.

I might be mistaken, but in one of the previous discussions I've been involved in on this very subject, someone had pointed to an epidemiological study on electric power line workers, a group that is disproportionately more exposed to HT lines and their magnetic fields, and there was no conclusive evidence of any increase rates of anything, including cancer. I'll see if I can find it.

RE: Mercury AND magnetic fields.

With a previous employer, we had a DeNora process (mercury cell) chlor-alkali unit. It used mercury, nice, shiny, elemental mercury by the ton, with the inevitable leaks. The input current for the cell line was 300 kA at 350 VDC. the magnetic field was strong enough to pull ferrous hand tools into the bus from six feet away.

We could find no 'off the shelf' technology to measure magnetic fields of this magnitude.

I worked there ten years. I'm perfectly normal except for the tendency to emit a soft bluish glow in the presence of electricity.
