Wireless radiation is emitted by the myriad of wireless devices we encounter every day. These devices communicate by transmitting radio frequency (RF) waves between networks of fixed antennas. RF waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, can neither break chemical bonds nor cause ionization in the human body. RF waves have been linked to the heating of biological tissue and an increase in body temperature at very high levels of exposure to RF energy. Studies including schools near cell towers have shown that environmental levels of RF energy routinely encountered by the general public are typically far below levels necessary to produce significant heating and increased body temperature.
As of current, there is insufficient scientific data to suggest that RF signals from base stations, wireless networks and mobile devices can cause severe adverse health effects. Scientists continue to study the effects of long-term exposure to low levels of RF.
If you are concerned, you can take these simple steps as recommended by the EPA to reduce your exposure to RF radiation from your wireless devices:
- Limit use - Reduce the number and length of your calls or time spent on a wireless device.
- Use hands-free devices - Using hands-free devices keeps mobile phones away from your head.
- Increase distance between the wireless device and your body.
