and brain tumors ever undertaken. WHO summarized its
conclusions concerning Interphone as follows: "Overall, no
increase in risk of glioma or meningioma was observed with use
of mobile phones. There were suggestions of an increased risk
of glioma at the highest exposure levels, but biases and error
prevent a causal interpretation. The possible effects of long-
term heavy use of mobile phones require further investigation."

What Does Specific Absorption Rate (SAR) Mean?
In 1996, the FCC, working with the FDA, the U.S. Environmental
Protection Agency (EPA) and other agencies, established RF
exposure safety guidelines for wireless devices in the United
States. Before a wireless device 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
wireless device transmitting at its highest power level in all
tested frequency bands. Since 1996, the FCC has required that
the SAR of handheld wireless devices 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 device while operating can be less than the reported
SAR value.
