ELECTROMAGNETIC POLLUTION
From ELF radiation from power lines

While only a portion of the population of the world is exposed to microwave radiation, most of the population is exposed to the 60Hz fields given off by the electrical web that surrounds the population. The 60Hz electric power frequency lies within the band termed "extremely low frequency" (ELF) , which covers the region zero (DC) to 100Hz.It was formally considered impossible for an ELF field to have any biological effect; the wave lengths average about 4800km. These ELF fields however have some interesting properties. They may be transmitted over great distances through the ionospheric cavity. The results of chronic expose to 60 KH electric fields are many. Dr Stephen Perry, who worked for the British National Health Service as a family practice physician in a rural area of England reported that he had observed that his patients who lived near electric power lines appeared to have a higher incidence of mental disturbances and suicide. Dr Nancy Wartheimer, an epidemiologist at the University of Colorado, was examining the possible relationship between the magnetic field from electrical lines (not the high voltage lines we previously discussed but the secondary lines that are strung everywhere). She made a startling discovery; 60Hz magnetic fields with the strengths of only three milligrams (three thousand of a gauss - the Earths magnetic field averages 0.5 gauss) were statistically related to the incidence of childhood cancers. This field strength is many times smaller, as mentioned above, then the earths normal magnetic field strength, and it is far below the average strength of 100MG at a distance of approximately 15 metres from the standard transmission line. Dr David Savitz of the University of North Carolina repeated the tests, he found that 20% of childhood cancers appeared to be produced by the exposure to 3 milligauss power frequency magnetic fields. Also found was that the power frequency fields had significant behavioural and central nervous system effects, as well as a stimulating effect on cancer cell growth. The magnetic field about 15metres away from a 345KV transmission line, averages 100 milliguass. From the above it stands to reason that we cannot get away from the problem completely, but we do have the choice to minimise our exposure. One of the first places to look is in your own home, where depending on the layout of the wiring it could be quite normal to find readings of 3 milliguass and above, possibly even from the plumbing. Avoidance is the best coarse of action. Beds and chairs can be moved away from the "hot spots" which can be measured with an electromagnetic measuring device such as the TriField. We believe that exposure can weaken the immune system further, helping to create an environment for disease.
Some examples:
Computers: The average computer will expose you to any thing from 1mg up to 100 millguass, depending on distance and type of computer.
Transformers: The worst being the cheap ones used in clock radios, usually placed close to the head of small children in their bedroom, 30cm away gives 3 mg.average.
