actually there may be already cable running below ground, just that you don't see it.
Yup. Even if you can see no power lines in your area, there may be underground cables much closer than you imagine.
Moreover, Power Line EMF may not be your greatest danger
Suppose that you are being exposed to a 1.0 mG EMF from living next to a power transmission line.
Its also possible that your exposure from the computer monitor you are now using could be 2.5 mG, and from your TV perhaps another 2.0 mG, and from your bedside clock-radio, another 1.0 mG.
