Magnetic field strength is commonly measured by an instrument called gaussmeter in milligauss. Measured by using a gaussmeter, the average ELF field strength from a computer VDT at a distance of 12 inches was 2.5 to 3.5 mG.(2) This figure compared to 0.9 to 1.3 mG at 3 feet in front of a television screen, 3.5 to 5 mG in the front seat of a car, and more than 10 mG under an older electric blanket.
In Irvine, Calif., an approved ballot measure prohibits new residential construction if the lot or proposed house is exposed to EMF levels of 4 milligauss (a measure of magnetic radiation) or more, despite the fact that no baseline of "safe" exposure has been determined.
The strenght of the 2 to 3 milligauss current (a gauss is a unit of strength of a magnetic field) emitted by the power lines was similar to the strength of the same type of emission measured at a distance of twelve inches from VDTs, according to 1982 studies by Dr.
Starting at a threshold dose of about 20 milligauss (a measure of the strength of the electrical field), the 60-hertz ELF-EMF caused a dose-dependent reduction of differentiation, as well as an increase in telomerase and proliferation.
The maximum energy field within the right of way of an electric transmission line is 100 mG (100 milligauss or 0.1 gauss).
At that time, he showed that while melatonin, a natural antioxidant hormone, would inhibit the growth of breast cancer cells exposed to 2 milligauss (mG) magnetic fields, its activity was essentially erased when the cells were bathed in a 12 mG field (SN: 7/3/93, p.
Several recent ones, and a 1990 Environmental Protection Agency (EPA) draft report, point to increased cancer risks for People with long-term exposure higher than two milligauss (mG).
Becker maintains that EMF levels greater than 3 milligauss (the unit of field intensity) are potentially hazardous to adults.
These line workers were exposed to an alternating current magnetic field with a mean level of 4.3 milligauss (a gauss is a unit of strength of a magnetic field).
