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.
The Swedish safety standard, effective 711/90, specifies a maximum of 0.25 mG at 50 cm from the display. Many US manufactured computers have EMFs of 5 - 100 mG at this distance. And know this too: the screens placed over monitors do NOT block EMFs. Not even a lead screen will block ELF and VLF magnetic fields.
Space does not permit a more thorough discussion of computers. If you use a computer, it is important that you
measure your EMF exposure with a Gauss meter and review the literature concerning the health impacts of computer use.
Electric Blankets and Waterbeds
Electric blankets create a magnetic field that penetrates about 6-7 inches into the body. Thus it is not surprising that an epidemiological study has linked electric blankets with miscarriages and childhood leukemia.
This pioneering work was performed by Dr. Nancy Wertheimer and Ed Leeper, who originally discovered that magnetic fields were linked to childhood leukemia. Similar health effects have been noted with users of many electric blankets and waterbed heaters will emit EMFs even when turned off.
The devices must be unplugged to delete the EMF exposure Additionally, there is the issue regarding the vibrations that are generated by sleeping on standing water. There is less hard data in this area but some experts are concerned about the consequences.
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 powerline Studies have linked high rates of brain tumors with chronic exposure to magnetic fields, so it is wise to place all clocks and other electrical devices (such as telephones and answering devices) at least 6 feet from your bed.
Fluorescent Lights
Fluorescent lights produce much more EMFs than incandescent bulbs. A typical fluorescent lamp of a office
ceiling have 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. Microwaves are measured in milliwatt per centimeter squared (mW/cm2) As of 1/1/93, the U.S. safety limit for microwave exposure is 1 mW/cm2, down from a previous 10 mW/cm2. The Russian safety limit is .01 mW/cm2. All microwave ovens leak and exceed the Russian safety limit. In addition, recent Russian studies have shown that normal microwave cooking coverts food protein molecules into carcinogenic substances.
When measuring microwaves from military and airport radar sources, 100% accurate readings can only be found with extremely expensive digital peak-hold meters. Why? Because analog devices begin to drop their reading immediately after the radar sweep passes. Thus, while an analog meter can show whether or not you are being exposed to radar EMFs, analog meters can't show your true exposure. Although thousands of dollars to purchase, digital-hold meters capable of accurately detecting radar EMFs can be rented for several hundred to over a thousand dollars per month.
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. Place the Gauss meter right against the ear piece and the mouth piece before buying a phone.
Some brands emit no measurable fields and others emit strong fields that travel several inches....right into your brain. Answering machines, particular those with adapter plugs (mini-transformers), give off high levels of EMFs.
Electric Razors and Hair Dryers
Electric razors and hair dryers emit EMFs as high as 200 to 400 mG. This seems alarming, but we don't know if this is worse (or better) than a chronic exposure to a 2-3 mG field. Some EMF consultants recommend that hair dryers not be used on children as the high fields are held close to their rapidly developing brain and nervous system.
One has had skin cancer three times and is only in her 20's
But I spent a lot of time in my childhood at pools, and my bowels are still intact, so I think it's probably a freak occurrence. 
She needs to acquire one of those lead aprons used by x-ray technicians...
