cancer promoting effect if one exists. Epidemiological studies can provide data

that is directly applicable to human populations, but 10 or more years follow-up

may be needed to provide answers about some health effects, such as cancer. This

is because the interval between the time of exposure to a cancer-causing agent and

the time tumors develop - if they do - may be many, many years. The interpretation

of epidemiological studies is hampered by difficulties in measuring actual RF

exposure during day-to-day use of wireless phones. Many factors affect this

measurement, such as the angle at which the phone is held, or which model of

phone is used.

What is FDA doing to find out more about the possible health effects of wireless
phone RF?

FDA is working with the U.S. National Toxicology Program and with groups of

investigators around the world to ensure that high priority animal studies are

conducted to address important questions about the effects of exposure to

radiofrequency energy (RF).
FDA has been a leading participant in the World 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.

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.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.
