Section 13: Health and Safety Information 140
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 radio
frequency 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 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.
What steps can I take to reduce my exposure to radio frequency 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 radio frequency
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.
• If you must conduct extended conversations by wireless phone every day, you
could place more distance between your body and the source of the RF, since
the exposure level drops off dramatically with distance. For example, you could
use a headset and carry the wireless phone away from your body or use a
wireless phone connected to a remote antenna.
Again, the scientific data do not demonstrate that wireless phones are harmful. But
if you are concerned about the RF exposure from these products, you can use
