Safety
Guidelines
7.How
can
I
find
out
how
much
radio
frequency
energy
exposure
I
can
get
by using
my
wireless
phone?
All
phones
sold
in
the
United
States
must
comply
with
Federal
Communications Commission
(FCC)
guidelines
that
limit
radio
frequency
energy
(RF)
exposures.
The FCC
established
these
guidelines
in
consultation
with
the
FDA
and
the
other
federal
health
and
safety
agencies.
The
FCC
limit
for
RF
exposure
from
wireless
telephones
is
set
at
a
Specific
Absorption
Rate
(SAR)
of
1.6
watts
per
kilogram
(1.6
W/kg).
The
FCC
limit
is
consistent
with
the
safety
standards
developed
by
the
Institute
of
Electrical
and
Electronic
Engineering
(IEEE)
and
the
National
Council
on
Radiation
Protection
and
Measurement.
The
exposure
limit
takes
into
consideration
the
body's
ability
to
remove
heat
from
the
tissues
that
absorb
energy
from
the
wireless
phone
and
is
set
well
below
levels
known
to
have
effects.
Manufacturers
of
wireless
phones
must
report
the
RF
exposure
level
for
each
model
of
phone
to
the
FCC.
The
FCC
website
(http://www.fcc.gov/oet/
rfsafety)
gives
directions
for
locating
the
FCC
identification
number
on
your
phone
so
you
can
find
your
phone's
RF
exposure
level
in
the
online
listing.
8.What
has
the
FDA
done
to
measure
the
radio
frequency
energy
coming
from
wireless
phones?
The
Institute
of
Electrical
and
Electronic
Engineers
(IEEE)
is
developing
a
technical
standard
for
measuring
the
radio
frequency
energy
(RF)
exposure
from
wireless
phones
and
other
wireless
handsets
with
the
participation
and
leadership
of
FDA
scientists
and
engineers.
The
standard,
'Recommended
Practice
for
Determining
the
Spatial-
Peak
Specific
Absorption
Rate
(SAR)
in
the
Human
Body
Due
to
Wireless
Communications
Devices:
Experimental
Techniques,'
sets
forth
the
first
consistent
test
methodology
for
measuring
the
rate
at
which
RF
is
deposited
in
the
heads
of
wireless
phone
users.
The
test
method
uses
a
tissue-
simulating
model
of
the
human
head.
Standardized
SAR
test
methodology
is
expected
to
greatly
improve
the
consistency
of
measurements
made
at
different
laboratories
on
the
same
phone.
SAR
is
the
measurement
of
the
amount
of
energy
absorbed
in
tissue,
either
by
the
whole
body
or
a
small
part
of
the
body.
It
is
measured
in
watts/kg
(or
milliwatts/g)
of
matter.
This
measurement
is
used
to
determine
whether
a
wireless
phone
complies
with
safety
guidelines.
