June 2000, the FDA entered into a cooperative research and development

agreement through which additional scientific research is being conducted.

The FCC issued its own website publication stating that “there is no scientific

evidence that proves that wireless phone usage can lead to cancer or a variety

of other problems, including headaches, dizziness or memory loss.”

This publication is available at http://www.fcc.gov/oet/rfsafety or through the

FCC at (888) 225-5322 or (888) CALL-FCC.

What does “SAR” mean?

In 1996, the FCC, working with the FDA, the U.S. Environmental Protection

Agency, and other agencies, established RF exposure safety guidelines

for wireless phones in the United States. Before a wireless phone model is

available for sale to the public, it must be tested by the manufacturer and

certified to the FCC that it does not exceed limits established by the FCC. One

of these limits is expressed as a Specific Absorption Rate, or “SAR.” SAR is a

measure of the rate of absorption of RF energy in the body. Tests for SAR are

conducted with the phone transmitting at its highest power level in all tested

frequency bands. Since 1996, the FCC has required that the SAR of handheld

wireless phones not exceed 1.6 watts per kilogram, averaged over one gram of

tissue.

Although the SAR is determined at the highest power level, the actual SAR

value of a wireless phone while operating can be less than the reported SAR

value. This is because the SAR value may vary from call to call, depending

on factors such as proximity to a cell site, the proximity of the phone to the

body while in use, and the use of hands-free devices. Before a phone model is

available for sale to the public, it must be tested and certified to the FCC that it

does not exceed the limit established by the government-adopted requirement

for safe exposure. The tests are performed in positions and locations (e.g., at

the ear and worn on the body) as required by the FCC for each model.

The highest SAR values are:

* Head: 0.63 W/kg

* Body (Body-worn/Hotspot): 1.10 W/kg

(body measurements differ among phone models, depending upon available
