If you want something fun to do walk under them at night with a flouresent light tube and for some reason it just glows. That should give you a fair idea.

Yes, it is safe. In October 2000, Discover magazine listed the twenty greatest engineering blunders of the past 20 years. EMF's made the list. Below is the article's text, along with a link to the magazine's online version of the article. Currents That Don't Kill The Clinton administration estimates that American taxpayers have paid $25 billion to determine that power lines don't do anything more deadly than deliver power. In 1989, Paul Brodeur published a series of articles in The New Yorker raising the possibility of a link between electromagnetic fields and cancer. Eight years later, after several enormous epidemiological studies in Canada, Britain, and the United States, the danger was completely discounted. "All known cancer-inducing agents act by breaking chemical bonds in DNA," says Robert Park. "The amount of photon energy it takes is an ultraviolet wavelength. So any wavelength that is longer cannot break chemical bonds. Visible light does not cause cancer. Infrared light is still longer, radio waves longer still. Power-line fields are preposterous. The wavelength is in miles."

As long as your house is about 200 to 500 m away, you are safe. As to all the discussion about radiation, remember that power lines are only providing triphase current at 60 Hz.
It isn't radiating power away. the power line length comes no where near half a wavelength. Power companies would not want this wastage - they'd rather get it to your home and charge you for the power... Current is kept as low as possible to reduce active power loss (resistance in the cable). That's why we have step down transformers close to the home so that the current is at it's highest just before it hits your house. The magnetic field produced is related to amount of current flowing. You are receiving a higher magnetic field from the electricity flowing in your home than you would from a high voltage power line. Also the magnetic field strength would drop inversely as the square of the distance, so the magnetic field strength from the power line would be 0.0025% (200 m away) of the strength if you stood underneath it.
In fact for those of you using cell phones, you get a higher dose of radiation from them than from power lines. Plus your brain is in the path of a near field coupling magnetic field. Lots of radiation pouring directly into your brain!

Very safe. They do not emit radiation (as in x-rays, etc) - they emit magnetic fields which is why fluorescent tubes illuminate when close. If you get away from electric towers because of the magnetic fields, you have to stay away from cars (wiring and their ignition emits fields), away from cell phones, TVs, computers, hair dryers, and vitrually anything else electric or electronic. Plus, the entire surface of the planet is bombarded with low power microwave frequencies from satellites (have Direct TV?), radio transmitters, cell phone repeaters, radar from TV stations and air ports, etc. If you are going to worry about one, worry about them all.

Not, really. It won't kill you or anything, but would you believe that all of the radiation they produce is really good for you. Then again, with all of the radiation we are constantly exposed to nowadays, we live longer, are generally more healthy (besides all of the different cancers, most likely caused by the excess radiation), and are evolving even further.

I have heard high incidence of leukemia(blood Cancer).I can't wait to see what my cell phone is doing to my head.When the owners manual has a vague warning.Maybe,I should invent Rad.head shield.

That's been debated for years.
All the studies... done and published by the power companies, suggest they are NOT dangerious.
But keep in mind... my dentist provides CANDY to their children clients. So what does THAT tell ya?

Not all that safe, because of the radiation emitted. It is a health risk.

they emit a field, but data isn't quantitative. can't say for sure, but it's probably not good thing to do for a long time
