5.What research is needed to decide whether RF exposure from wireless
phones poses a health risk?
A combination of laboratory studies and epidemiological studies of people actually
using wireless phones would provide some of the data that are needed. Lifetime animal
exposure studies could be completed in a few years. However, very large numbers of
animals would be needed to provide reliable proof of a 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.
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.
