What
steps
can
I
take
to
reduce
my
exposure
to
radio
frequency
energy
from
my
wireless
phone?
If
there
is
a
risk
from
these
products
---
and
at
this
point
we
do
not
know
that
there
is
---
it
is
probably
very
small.
But
if
you
are
concerned
about
avoiding
even
potential
risks,
you
can
take
a
few
simple
steps
to
minimize
your
exposure
to
radio
frequency
energy
(RF).
Since
time
is
a
key
factor
in
how
much
exposure
a
person
receives,
reducing
the
amount
of
time
spent
using
a
wireless
phone
will
reduce
RF
exposure.
If
you
must
conduct extended
conversations
by
wireless
phone
every
day,
you
could
place
more
distance
between
your
body
and
the
source
of
the
RF,
since
the
exposure
level
drops
off
dramatically
with
distance.
For
example,
you
could
use
a
headset
and
carry
the
wireless
phone
away
from
your
body
or
use
a
wireless
phone
connected
to
a
remote
antenna.
Again,
the
scientific
data
do
not
demonstrate
that
wireless
phones
are
harmful.
But
if
you
are
concerned
about
the
RF
exposure
from
these
products,
you
can use
measures
like
those
described
above
to
reduce
your
RF
exposure
from
wireless
phone
use.

What
about
children
using
wireless
phones?
The
scientific
evidence
does
not
show
a
danger
to
users
of
wireless
phones,
including
children
and
teenagers.
If
you
want
to
take
steps
to
lower
exposure
to
radio
frequency
energy
(RF),
the
measures
described
above
would
apply
to
children
and
teenagers
using
wireless
phones.
Reducing
the
time
of
wireless
phone
use
and
increasing
the
distance
between
the
user
and
the
RF
source
will
reduce
RF
exposure.
Some
groups
sponsored
by
other
national
governments
have
advised
that
children
be
discouraged
from
using
wireless
phones
at
all.
For
example,
the
government
in
the
United
Kingdom
distributed
leaflets
containing
such
a
recommendation
in
December
2000.
They
noted
that
no
evidence
exists
that
using
a
wireless
phone
causes
brain
tumors
or
other
ill
effects.
Their
recommendation
to
limit
wireless
phone
use
by
children
was
strictly
precautionary;
it
was
not
based
on
scientific
evidence
that
any
health
hazard
exists.

What
about
wireless
phone
interference
with
medical
equipment?
Radio
frequency
energy
(RF)
from
wireless
phones
can
interact
with
some
electronic
devices.
For
this
reason,
the
FDA
helped
develop
a
detailed
test
method
to
measure
electromagnetic
interference
(EMI)
of
implanted
cardiac
pacemakers
and
defibrillators
from
wireless
telephones.
This
test
method
is
now
part
of
a
standard
sponsored
by
the
Association
for
the
Advancement
of
Medical
instrumentation
(AAMI).
The
final
draft,
a
joint
effort
by
the
FDA,
medical
device
manufacturers,
and
many
other
groups,
was
completed
in
late
2000.
This
standard
will
allow
manufacturers
to
ensure
that
cardiac
pacemakers
and
defibrillators
are
safe
from
wireless
phone
EMI.
The
FDA
has
tested
hearing
aids
for
interference
from
handheld
wireless
phones
and
helped
develop
a
voluntary
standard
sponsored
by
the
Institute
of
Electrical
and
Electronic
Engineers
(IEEE).
This
standard
specifies
test
methods
and
performance
requirements
for
hearing
aids
and
wireless
phones
so
that
no
interference
occurs
when
a
person
uses
a
"compatible"
phone
and
a
"compatible"
hearing
aid
at
the
same
time.
This
standard
was
approved
by
the
IEEE
in
2000.
The
FDA
continues
to
monitor
the
use
of
wireless
phones
for
possible
interactions
with
other
medical
devices.
Should
harmful
interference
be
found
to
occur,
the
FDA
will
conduct
testing
to
assess
the
interference
and
work
to
resolve
the
problem.
