Cell Phones

Several major studies show no link between cell phones and cancer at this time. However, since the information available is based on short-term studies, there is no definitive answer at this time.

The amount of time people spend on cell phones has increased and will be taken into consideration during current and future studies. Research will continue to investigate whether there is a relationship between slow-growing tumors in the brain or elsewhere with long-term cell phone use.

WHAT WE KNOW ABOUT CELL PHONE USE

Cell phones use low levels of radiofrequency energy (RF). Exposures to low levels of RF from cell phones have not been found to cause health problems.

The U.S. Food and Drug Administration (FDA) and the Federal Communications Commission (FCC) have developed guidelines that limit the amount of radiofrequency energy that cell phones are allowed to give off.

The RF exposure from cell phones is measured in Specific Absorption Rate (SAR). The SAR measures the amount of energy absorbed by the body. The SAR permitted in the United States is 1.6 watts per kilogram (1.6W/kg).

According to the FCC, this amount is much lower than the level shown to cause any changes in laboratory animals. Every cell phone manufacturer is required to report the RF exposure of each of its phone models to the FCC.

CHILDREN AND CELL PHONES

Generally, cell phone studies have involved adults aged 18 or older. Most children didn't use cell phones until the mid-1990s. This leaves the effects of cell phone use on children unclear.

Other national governments have recommended that children be discouraged from using cell phones. In December 2000, the British government handed out pamphlets that recommended reducing the amount of time children spend on a cell phone. However, there was no scientific evidence confirming or denying a health risk.

CELL PHONES AND DRIVING

The risk of being in a car accident while talking on a cell phone is higher than any risk for cancer.
