Does living near or under high or low power transmission cables cause cancer in humans expecially children?
Answer:
As you correctly state, power lines can be divided into transmission lines (those high voltage lines mounted on large steel towers) and distribution lines (those like the ones that run in most streets mounted on wooden or concrete poles and connect directly to your home).
Transmission lines generate both strong electric fields and strong magnetic fields. whilst distribution lines generate weak electric fields, but can generate strong magnetic fields.
Human studies have consistently shown that there is no evidence that prolonged exposure to weak electric fields (such as those found in the home, around distribution lines or in most workplaces), results in adverse health effects. Whether chronic exposure to weak magnetic fields is equally harmless remains an open question. There is no evidence that these fields cause immediate, permanent harm.
However, laboratory studies on animals and cell cultures have shown that weak magnetic fields can have effects on several biological processes. For example, they may alter hormone and enzyme levels and the rate of movement of some chemicals through living tissue. By themselves, these changes do not appear to constitute a health hazard. In the long term, they may have an effect on the incidence of cancer or other adverse health effects. While most studies have produced inconclusive results or no increased cancer incidence in laboratory animals following exposure to EMFs, a few studies have indicated an increased incidence of cancer.
Nevertheless, the National Health and Medical Research Council has issued Interim guidelines on limits of exposure to 50/60 Hz electric and magnetic fields. These guidelines are aimed at preventing immediate health effects resulting from acute exposure to these fields. The recommended magnetic field exposure limit for members of the public (24 hour exposure) is 1,000 mG (0.1 milliTesla) and for occupational exposure (whole working day) is 5,000 mG (0.5 milliTesla).
As an indicative comparison, exposure levels to EMFs around the home are typically 0.1 - 2.5 mG. For homes near powerlines, these levels may be as high as 5 - 10 mG. Immediately under the powerline, magnetic field levels of 60 - 100 mG may be found.
Where does that leave one?? Well, personnally you wouldn't be able to pay me enough to live anywhere near HV Transmission lines (typically 220KV to 500KV) and certainly not with young children that are more susceptable to the possible effects of electromagnetic radiation.
Following are some additional sources that may be of interest.
Answer:
There has been no scientific evidence to prove that theory, as far as I know.
Answer:
There have been reports that this is dangerous.
If you want a serious answer, do some research. Don't come here looking for an answer to such a serious question.
Answer:
Many people frighten with this condition, live under high voltages power transmisions which have light if test pen put in the wall. But the expert believe that it's not good conditions for living there. It's crucial conditions because the government can change this opinion with the power. So The people can't choice although The serious problem could came with this condition???
Answer:
If power transmission cables caused cancer in humans than why don't every single person living near or beside these cables get cancer? The answer is that they do not get any more cancer than any other segment of the population. You should keep in mind the reliability of any 'report' trying to make connections to cancer. There is at least one biochemist who basically fabricated the connection between EMF and cancer and purposely misled the public:
