Health Organization International Electromagnetic Fields (EMF) Project since its
inception in 1996. An influential result of this work has been the development
of a detailed agenda of research needs that has driven the establishment of new
research programs around the world.
The Project has also helped develop a series of public information documents
on EMF issues. FDA and the Cellular Telecommunications & Internet Association
(CTIA) have a formal Cooperative Research and Development Agreement
(CRADA) to do research on wireless phone safety. FDA provides the scientific
oversight, obtaining input from experts in government, industry, and academic
organizations. CTIA-funded research is conducted through contracts to
independent investigators. The initial research will include both laboratory
studies and studies of wireless phone users. The CRADA will also include a broad
assessment of additional research needs in the context of the latest research
developments around the world.
7. How can I find out how much radiofrequency 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 radiofrequency energy (RF) exposures.
FCC established these guidelines in consultation with 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.fda.gov
(under “c” in the subject index, select Cell Phones > Research )) 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 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.
