Safety

	studies mean for human health.
	Three large epidemiology studies
	have been published since
	December 2000. Between them,
	the studies investigated any
	possible association between the
	use of wireless phones 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
Safety	any harmful health effects from
	wireless phone RF exposures.
	However, none of the studies can
	answer questions about long-
	term exposures, since the
	average period of phone use in
	these studies was around three
	years.
	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 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
