Almost 70 percent of Canadian households have at least one cell phone, but there could be hidden hazards to this modern-age convenience.

University of Washington researchers began questioning cell phone safety in 1994, when two hours of low-level electromagnetic radiation altered rat brain DNA.

Dr. George Carlo, co-author of Cell Phones: Invisible Hazards in a Wireless Age (Carroll and Graf, 2001) has shown increased risk of brain cancer deaths and tumour development related to cell phone use.

In the United Kingdom, children in particular are encouraged to use cell phones only during emergencies, as developing immune systems are more susceptible to possible EMF effects.

To reduce radiation exposure:
•        If you have a choice, use a landline (wired, not cordless).
•        Limit the length of your calls.
•        Use an ear bud.
•        Make sure the wire isn't near the antenna, and have at least one coil in the wire.
•        Cell phone radiation has an affinity to metal and water, so metal-framed glasses, earrings, and wet hair will attract it.
•        When your phone is on, it automatically transmits at high power to check in to the network every minute or two. So, don't wear it on your belt or carry it in a breast or pants pocket.
•        When placing a call, the phone makes the connection at high power, so count to five before putting it to your ear, and don't press it against your head.
•        Try to use your phone where reception is good. Power cranks up to compensate for a weak signal.
