7. How can I find out how much radio frequency energy
exposure I can get by using my wireless phone?
All phones sold in the United States must comply with
Federal Communications Commission (FCC) guidelines that
limit radio frequency energy (RF) exposures. The FCC
established these guidelines in consultation with the FDA
and the other federal health and safety agencies. The FCC
limit for RF exposure from wireless telephones is set at a
Specific Absorption Rate (SAR) of 1.6 watts per kilogram (1.6
W/kg). The FCC limit is consistent with the safety standards
developed by the Institute of Electrical and Electronic
Engineering (IEEE) and the National Council on Radiation
Protection and Measurement. The exposure limit takes into
consideration the body’s ability to remove heat from the
tissues that absorb energy from the wireless phone and is
set well below levels known to have effects. Manufacturers
of wireless phones must report the RF exposure level for
each model of phone to the FCC. 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 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
tissuesimulating 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
