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.
6.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.
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.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 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
