association between the use of wireless devices and primary brain cancer, glioma,
meningioma, or acoustic neuroma, tumors of the brain or salivary gland, leukemia, or
other cancers. None of the studies demonstrated the existence of any harmful health
effects from wireless device RF exposures. However, none of the studies can answer
questions about long-term exposures, since the average period of device use in these
studies was around three years.
5. What research is needed to decide whether RF exposure from
tablets poses a health risk?
A combination of laboratory studies and epidemiological studies of people actually
using tablets 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 ten 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 tablets. Many
factors affect this measurement, such as the angle at which the tablet is held, or which
model of tablet is used.
6. What is the FDA doing to find out more about the possible health
effects of tablet 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
