At a distance of about 300 ft. at times of average electricity demand, the magnetic field from many lines can be similar to typical background EMF levels found in most homes. The distance at which the magnetic field from the line becomes indistinguishable from typical background EMFs differs for different types of lines. Neighborhood distribution [...]

Government actions about Electro Magnetic Frequency radiation and cancer
Q. What have governmental reviews concluded about EMFs and cancer? A. Most recent reviews have concluded that the existing evidence, although suggestive, is not sufficient to show that EMFs cause cancer. These include national reviews by the U.S. Environmental Protection Agency, the Committee on Interagency Radiation Research and Policy Coordination, the Australian Minister of Health, [...]

Biological studies of the effect of Electro Magnetic Frequency Radiation
Q. What effects of EMFs have been reported in laboratory studies? A. Several kinds of biological effects have been reported in studies of electric and /or magnetic fields (see below). A biological effect is a measurable change in some biological factor. It may or may not have any bearing on health. Overall, effects attributed to [...]

Possible effects of Electro Magnetic Frequency radiation on human health
Q. How do scientists study possible effects of EMFs on people? A. They use a type of research called epidemiology-the study of patterns and possible causes of diseases in human populations. Epidemiologists study short-term epidemics such as outbreaks of food poisoning and long-term diseases such as cancer and heart disease. Results of these studies are [...]

Scientific Principles of Electro Magnetic Frequency
Q. What are EMFs? A. Power lines, electrical wiring, and appliances all produce electric and magnetic fields. EMFs are invisible lines of force that surround any electrical device. Electric and magnetic fields have different properties and possibly different ways of causing biological effects. Note that while electric fields are easily shielded or weakened by conducting [...]

AC/DC of Electro Magnetic Frequency
Appliances that operate either with batteries or by plugging into the household wiring usually come equipped with an AC /DC switch. If switched to AC, the appliance uses electric power that flows back and forth or “alternates” at a (U.S.) rate of 60 cycles per second (60 hertz, or Hz). If DC (“direct current”) is [...]

Electric Power Facilities and Electro Magnetic Frequency
There are two basic types of power lines: transmission lines and distribution lines. Transmission lines are high-voltage power lines. The high voltage allows electric power to be carried efficiently over long distances from electrical generation facilities to substations near urban areas. In the United States, most transmission lines use alternating current (AC) and operate at [...]

Basic electrical terms
This article uses six basic electrical terms- conductor, current, voltage, load, power, and circuit. The conductor is the wire you see between power poles or towers; it carries the electricity. Current is the movement of electrons in the conductor. Voltage is the electric force that causes current in a conductor. Load is the electric power [...]

An introduction of Electro Magnetic Frequency Radiation
Electric power is a fact of life in America, a familiar miracle. Generations have come to take for granted the simple flip of a switch that turns night into day. With electric power, however, come certain precautions that are also well known. Electric power lines, household wiring, and appliances can cause serious injury from electric [...]
