The World Health Organization has classified the mobile phones in the category of products which use is "possibly carcinogenic". If their harmfulness is not formally demonstrated, scholars have already shown that heavy users appeared to have a greater risk of developing cancer in the head (brain, parotid gland, inner ear). It is therefore necessary to minimize, at least as a precaution, exposure.

Use the speakerphone or handsfree

The amount of waves absorbed by the body decreases rapidly when keeping the phone aside. Use the loudspeaker to limit its exposure. Similarly, hands free kits are very effective even if a very small waves propagate along the wire.

Bluetooth kits work on the same frequency range as laptops (or Wi-Fi). But their emission is more than 200 times less safe. While in standby mode they are commendable. Otherwise, while talking on the phone they can instead make things worse.

Limit moving while conversation

The phones do not emit systematically with the same power. When you start a conversation when the phone connects with the relay antenna, it is more important example.

When you are moving (subway, car, train), your phone also emits more strongly to search for nearby antennas. And when the signal is weak, your phone tries to compensate it by sending more powerful waves. In both cases, it is better to avoid moving while using the cell phone.

Note that cordless phones (also known as DECT) operate on the same wavelength range but emit about ten times less power.

Prioritize mails and SMS

Speak no more. Write. In this way, you keep your phone away from your ear and you limit the amount of waves cell phone emits.

Do not keep your phone close to you

Your phone emits at very short intervals to keep in touch with the network (or 3G telephony). Better not to leave your phone on your desktop, in your pocket, in your living room on your bedside table. Most phones now have a function "airplane" that lets you disconnect your terminal from the network and benefit from other applications (alarm clock, games, etc.).

Buy a phone with a small SAR?

Cell phones all have a SAR (Specific Absorption Rate) which gives the amount of absorbed wave by human tissues for a maximum emission. Limited to 2W/kg in Europe (1.6W/kg in the U.S.), it is measured by the manufacturer itself has a legal obligation to mention it in the manual. Some websites will enumerate the values ​​to allow comparisons.

Teenage drivers are the worst offenders when it comes to distraction by electronic devices, especially by cell phones.
As you might expect, teenage drivers, who statistics demonstrate are already handicapped by immaturity, poor decision-making skills, lack of experience and inadequate risk perception, are the worst offenders when it comes to distraction by electronic devices, because cell phone texting is their primary means of communication.
