leukemia,
or
other
cancers.
None
of
the
studies
demonstrated
the
existence
of
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
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
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
radiofrequency
energy
(RF).
The
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.
