The
U.S.
Food
and
Drug
Administration's
Center
for
Devices
and
Radiological
Health
Consumer
Update
on
Mobile
Phones:
1.
Do
wireless
phones
pose
a
health
hazard?
The
available
scientific
evidence
does
not
show
that
any
health
problems
are
associated
with
using
wireless
phones.
There
is
no
proof,
however,
that
wireless
phones
are
absolutely
safe.
Wireless
phones
emit
low
levels
of
radiofrequency
energy
(RF)
in
the
microwave
range
while
being
used.
They
also
emit
very
low
levels
of
RF
when
in
the
standby
mode.
Whereas
high
levels
of
RF
can
produce
health
effects
(by
heating
tissue),
exposure
to
low
level
RF
that
does
not
produce
heating
effects
causes
no
known
adverse
health
effects.
Many
studies
of
low
level
RF
exposures
have
not
found
any
biological
effects.
Some
studies
have
suggested
that
some
biological
effects
may
occur,
but
such
findings
have
not
been
confirmed
by
additional
research.
In
some
cases,
other
researchers
have
had
difficulty
in
reproducing
those
studies,
or
in
determining
the
reasons
for
inconsistent
results.
2.
What
is
the
FDA's
role
concerning
the
safety
of
wireless
phones?
Under
the
law,
the
FDA
does
not
review
the
safety
of
radiation-
emitting
consumer
products
such
as
wireless
phones
before
they
can
be
sold,
as
it
does
with
new
drugs
or
medical
devices.
However,
the
agency
has
authority
to
take
action
if
wireless
phones
are
shown
to
emit
radiofrequency
energy
(RF)
at
a
level
that
is
hazardous
to
the
user.
In
such
a
case,
the
FDA
could
require
the
manufacturers
of
wireless
phones
to
notify
users
of
the
health
hazard
and
to
repair,
replace,
or
recall
the
phones
so
that
the
hazard
no
longer
exists.
Although
the
existing
scientific
data
do
not
justify
FDA
regulatory
actions,
the
FDA
has
urged
the
wireless
phone
industry
to
take
a
number
of
steps,
including
the
following:
Support
needed
research
into
possible
biological
effects
of
RF
of
the
type
emitted
by
wireless
phones;
Design
wireless
phones
in
a
way
that
minimizes
any
RF
exposure
to
the
user
that
is
not
necessary
for
device
function;
and
Cooperate
in
providing
users
of
wireless
phones
with
the
best
possible
information
on
possible
effects
of
wireless
phone
use
on
human
health.
The
FDA
belongs
to
an
interagency
working
group
of
the
federal
agencies
that
have
responsibility
for different
aspects
of
RF
safety
to
ensure
coordinated
efforts
at
the
federal
level.
The
following
agencies
belong
to
this
working
group:
National
Institute
for
Occupational
Safety
and
Health
Environmental
Protection
Agency
Occupational
Safety
and
Health
Administration
National
Telecommunications
and
Information
Administration
The
National
Institutes
of
Health
participates
in
some
interagency
working
group
activities,
as
well.
The
FDA
shares
regulatory
responsibilities
for
wireless
phones
with
the
Federal
Communications
Commission
(FCC).
All
phones
that
are
sold
in
the
United
States
must
comply
with
FCC
safety
guidelines
that
limit
RF
exposure.
The
FCC
relies
on
the
FDA
and
other
health
agencies
for
safety
questions
about
wireless
phones.
The
FCC
also
regulates
the
base
stations
that
the
wireless
phone
networks
rely
upon.
While
these
base
stations
operate
at
higher
power
than
do
the
wireless
phones
themselves,
the
RF
exposures
that
people
get
from
these
base
stations
are
typically
thousands
of
times lower
than
those
they
can
get
from
wireless
phones.
Base
stations
are
thus
not
the
subject
of
the
safety
questions
discussed
in
this
document.
