protect yourself and your family
For some time, the standard recommendation was to use a headset. It was thought that since radiation decreases exponentially over the distance between you and the phone, this would solve the problem.
But, newer investigations, and the emergence of wireless earpieces (like Bluetooth) turns this idea upside-down. These headsets may actually intensify your exposure to harmful radiation because the headset itself acts as an antenna, which is now inserted directly into the ear canal.
To date, there are few alternatives to ensure complete safety, but there are some common sense recommendations:
.Limit the amount of time you spend on the phone.
.Use the speakerphone instead of putting the phone to your ear. This is probably one of the single most important steps you can take other than not using your cell phone.
.Use a non-Bluetooth (wired) headset to limit your exposure to the cell phone. Better yet would be use an air tube headset which conducts sound but prevents any radiation from travelling up the wire to your brain.
.Attach a ferrite bead to your headset to decrease RF (radio frequency) interference
.Limit calls inside buildings.
.Use the phone in open spaces as often as possible.
.Limit use by children and preadolescents.
.Keep the phone at least 4meters away from your body when sleeping
.Don’t use the phone when the battery life is low – radiation increases exponentially
Ferrite is a semi-magnetic substance created from iron oxide (rust) alloyed with other materials. It is commonly used on computer cables, to reduce or eliminate the radio frequency interference emitted by these cables.
A computer cable is essentially a really long antenna for the radio signals they carry, which can produce interference with radios and TV’s. Likewise, a headset to your cell phone is one long antenna, directing RF waves into your ear.
The idea behind using ferrite beads on your headset is fairly simple. Since radio waves can cause interference with the cellular functions in your brain—just like a computer cable can create static noise on your radio—the ferrite beads reduce the radio frequency interference broadcast by your phone through the headset, to your brain.
