Limit your calls : Many of us make unnecessary calls. Reducing needless calls will reduce radiation exposure.
Wear an air tube headset : The regular wired headset has been found to intensify radiation into the ear canal. The wire transmits not only the radiation from the cell phone but also serves as an antenna attracting electromagnetic fields from the surroundings.
Don’t put the cell phone in your pocket or belt : The body tissue in the lower body area has good conductivity and absorbs radiation more rapidly than the head. One study shows that men who wear cell phones near their groin could have their sperm count dropped by as much as 30 percent.
Purchase a phone with a low SAR (Specific Absorption Rate) : Most mobile phones have a SAR level listed in its instruction manual. The SAR level is a way of measuring the quantity of radiofrequency (RF) energy that is absorbed by the body.
Use a scientifically validated EMF protection device : There are advanced technologies obtainable nowadays that strengthen the immune system against the effects of EMF. The EMF radiation causes a problem only when the cumulative effects due to repeated exposure weaken the body’s ability to repair it.
Other steps :
If using the phone without a headset, wait for the call to connect before placing the phone next to the ear.
Do not use the cell phone in enclosed metal spaces such as vehicles or elevators, where devices may use more power to establish connection. The metal enclosure also acts as a Faraday cage that traps the radiation and reflects it back onto the occupants.
Do not make a call when the signal strength is one bar or less, which means the phone must work harder to establish a connection.
Children should be allowed to use the cell phone in cases of emergency only. Because of their developing skulls, the radiation can penetrate much more deeply.
Avoid carrying cell phone on the body at all times. Do not keep it near the body at night such as under the pillow or on a bedside table, particularly if pregnant. You can also put it on “flight” or “off-line” mode, which stops electromagnetic emissions.
Make sure that the keypad is positioned toward the body and the back is positioned toward the outside while carrying it, so that the transmitted electromagnetic fields move away from you.
Avoid using the cell phone when the signal is weak or when moving at high speed, such as in a car or train, as this automatically increases power to a maximum as the phone repeatedly attempts to connect to a new relay antenna.
When possible, communicate by text messaging rather than making a call.
