Electromagnetic radiation and health

The preponderance of evidence does not suggest that the low-power, low-frequency, electromagnetic radiation associated with household current constitutes a short or long term health hazard. Some studies have found statistical correlations between various diseases and living or working near power lines, but no adverse health effects have been substantiated for people not living close to powerlines.[19]
There are established biological effects for acute high level exposure to magnetic fields well above 100 ?T. In a residential setting, there is "limited evidence of carcinogenicity in humans and less than sufficient evidence for carcinogenicity in experimental animals", in particular, childhood leukaemia, associated with average exposure to residential power-frequency magnetic field above 0.3 to 0.4 ?T. These levels exceed average residential power-frequency magnetic fields in homes which are about 0.07 ?T in Europe and 0.11 ?T in North America.[20][21]
