8. What has the FDA done to measure the radiofrequency energy
coming from wireless phones?
The Institute of Electrical and Electronic Engineers (IEEE) is developing a technical
standard for measuring the radiofrequency energy (RF) exposure from wireless
phones and other wireless handsets with the participation and leadership of FDA
scientists and engineers. The standard, 'Recommended Practice for Determining
the Spatial- Peak Specific Absorption Rate (SAR) in the Human Body Due to
Wireless Communications Devices: Experimental Techniques, ' sets forth the first
consistent test methodology for measuring the rate at which RF is deposited
in the heads of wireless phone users. The test method uses a tissue simulating
model of the human head. Standardized SAR test methodology is expected to
greatly improve the consistency of measurements made at different laboratories
on the same phone. SAR is the measurement of the amount of energy absorbed
in tissue, either by the whole body or a small part of the body. It is measured in
watts/kg (or milliwatts/g) of matter. This measurement is used to determine
whether a wireless phone complies with safety guidelines.
9. What steps can I take to reduce my exposure to
radiofrequency energy from my wireless phone?
If there is a risk from these products - and at this point we do not know that
there is - it is probably very small. But if you are concerned about avoiding even
potential risks, you can take a few simple steps to minimize your exposure to
radiofrequency energy (RF). Since time is a key factor in how much exposure a
person receives, reducing the amount of time spent using a wireless phone will
reduce RF exposure. If you must conduct extended conversations by wireless
phone every day, you could place more distance between your body and the
source of the RF, since the exposure level drops off dramatically with distance. For
example, you could use a headset and carry the wireless phone away from your
body or use a wireless phone connected to a remote antenna. Again, the scientific
data does not demonstrate that wireless phones are harmful. But if you are
concerned about the RF exposure from these products, you can use measures like
those described above to reduce your RF exposure from wireless phone use.
