1.
Mobile phones and base stations use radio waves (electromagnetic fields or non-ionizing radiation) to send and receive speech, text messages, pictures and other data. Radio waves have for long been used for different types of wireless communication, like for instance radio and TV broadcasting. It is important not to confuse radio waves with radioactive radiation. An example of radioactive radiation is gamma rays, a type of ionizing radiation generated by nuclear materials.

Extensive research over the course of many years has not established any conclusive evidence of a link between adverse health effects and the use of mobile phones.

3.
Yes, there are safety limits on exposure to radio waves. International and national health authorities, such as the World Health Organization (WHO), have adopted science-based safety guidelines specifying radio wave exposure limits. The limits were developed by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and have been set with wide margins to provide protection from established adverse effects on health.

It has been well known for many years that very high levels of radio wave exposure can heat the body tissue by energy absorption. The safety limits have been set with a fifty-fold margin to avoid temperature levels causing adverse health effects.

SAR stands for Specific Absorption Rate and is a measure of the rate of radio energy absorption in body tissue. Radio wave exposure limits are expressed as SAR levels in unit W/kg (watt per kilogram).

Yes, Sony Ericsson's mobile phone models are tested during development to meet relevant SAR standards.
7.
All new phone models have easy-to-read and up-to-date SAR information in the packaging, including the maximum SAR value. The SAR information can be found on Sony Ericsson's website or the website of Mobile Manufacturers Forum, MMF.

No. Variations in SAR do not mean that there are variations in safety. While there may be differences in SAR levels among phone models, all models must meet radio wave exposure guidelines.

Present scientific information does not indicate the need for any special precautions for use of mobile phones. However, the World Health Organization (WHO) gives some guidance for people how want to further limit their exposure to radio frequency energy.

Personal handsfree devices or headsets are designed for convenient, handsfree operation of the phone and not for safety reasons. Nevertheless, the results of tests over the years indicate that hands-free devices can significantly reduce the radio wave exposure of the head.

According to the World Health Organization (WHO), "[s]cientific evidence does not indicate any need for RF-absorbing covers or other "absorbing devices" on mobile phones. They cannot be justified on health grounds and the effectiveness of many such devices in reducing RF exposure is unproven."

Yes. There is only a small area in front of the antennas where the exposure could exceed the safety limits. The size of this area varies from a few centimeters up to a few meters, depending on the amount of power transmitted. The antennas are to be installed in such a way that people cannot get into this area.

No. To give coverage over a wider area, the antennas direct the radio waves away from the buildings they are mounted on. The antennas could be compared to the headlights of a car, which light up the road, but not the car itself. Inside and around the building, the intensity of the radio waves is far below the guidelines and is similar to that from radio and television transmitters.
