For Your Safety
The FCC website (http://www.fcc.gov/oet/rfsafety) gives directions for locating the FCC
identification number on your phone so you can find your phone’s RF exposure level in the
online listing.
8. What has the FDA done to measure the Radio Frequency energy coming from wireless
phones?
The Institute of Electrical and Electronic Engineers (IEEE) is developing a technical standard
for measuring the Radio Frequency (RF) energy 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 Radio Frequency 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 Radio Frequency (RF) energy.
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.
