Electro-magnetic radiation (EMF) is produced by all alternating current sources. Your hair dryer, since it has a stationary brushes in contact with the revolving commutator, releases electro-magnetic radiation as current reversal occurs as the rotor rotates from pole to pole. Both your computer and monitor creates emit EMFs. Here is the List:
Sources of EMF:
Power Lines:
An enormous amount of electricity is created at power generating stations and sent across the country through wires that carry high voltages. All power lines radiate electromagnetic fields.
Transformer:
EMFs near a transformer can be quite high, but due to its small structure, the field strength diminishes rapidly with distance, as it does from any point source.
Home Wiring:
Loop wiring in the home may create large EMF.
Computers:
Computers are a complicated subject. Know this: EMFs radiate from all sides of the computer. Thus, you must not only be concerned with sitting in front of the monitor but also if you are sitting near a computer or if a computer is operating in a nearby room.
Electric Blankets and Water beds:
Electric blankets create a magnetic field that penetrates about 6-7 inches into the body.
Electric Clocks:
Electric clocks have a very high magnetic field, as much as 5 to 10 mG up to three feet away. If you are using a bedside clock, you are probably sleeping in an EMF equivalent to that of a power line.
Fluorescent Lights:
Fluorescent lights produce much more EMFs than incandescent bulbs. A typical fluorescent lamp has readings of 160 to 200 mg 1 inch away.
Microwave Ovens and Radar:
Microwave ovens and radar from military installations and airports emit two types of radiation–microwave and ELF.
Telephones and Answering Machines:
Telephones can emit surprisingly strong EMFs, especially from the handset. This is a problem because we hold the telephone so close to our head.
Electric Razors and Hair Dryers:
Electric razors and hair dryers emit EMFs as high as 200 to 400 mG.
You left out spectral activity.
The ghost hunters use EMF all the time to detect ghost and the like.
Pesky as heck!
This is bullcrap. Stop trying to scare ignorant people. Ask someone who knows. I’ve been an RF engineer almost 30 years. I’ve measured and calculated RF emissions on too many products to count.
