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 the FDA doing to find out more
about the possible health effects of wireless
phone RF?
The 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 (RF) energy.
The FDA has been a leading participant in the
World Health Organization International Electro
Magnetic 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
