Safety
Guidelines
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:
o
National
Institute
for
Occupational
Safety
and
Health
o
Environmental
Protection
Agency
o
Occupational
Safety
and
Health
Administration
o
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.
3.What
kinds
of
phones
are
the
subject
of
this
update?
The
term
'wireless
phone'
refers
here
to
handheld
wireless
phones
with
built-in
antennas,
often
called
'cell',
'mobile',
or
'PCS'
phones.
These
types
of
wireless
phones
can
expose
the
user
to
measurable
radiofrequency
energy
(RF)
because
of
the
short
distance
between
the
phone
and
the
user's
head.
These
RF
exposures
are
limited
by
FCC
safety
guidelines
that
were
developed
with
the
advice
of
the
FDA
and
other
federal
health
and
safety
