How Safe Are Bluetooth Headsets for
Your Brain?
By Russell Huebsch, eHow Contributor
Bluetooth headsets use wireless
technology to transmit voice data over
short distances, but have a relatively
high bandwidth. Because their
electromagnetic waves transmit
radiation, some people worry about
the effect this device has on the brain.
MisconceptionsAccording to HelloDirect.com,
Bluetooth headsets do emit some
levels of radiation, but much less
than that of an average cell phone
-- 65 to 70 percent less in a study
by the company SARtest and
commissioned by the UK
Department of Trade and Industry.
ConsiderationsSinxe 2005, the United States has
considered any absorption of
radiation by the human body
above 1.6 watts per kilogram from
electronic devices as dangerous.
However,
Bluetooth headsets only
emit about 0.001 watts per
kilogram. Even cell phones, such
as the
BlackBerry, only release
about 0.25 watts per kilogram.
BenefitsIn general, people who use
Bluetooth headsets tend to hold
their cell phones far away from
the brain -- usually in a pocket --
further reducing the effect of
radio wave radiation.
ConsiderationsEven headset and cell phone
configurations that placed both of
them close to the head in the UK
test showed that most of the
radiation collected around the
cheeks, not the brain.
TipsWhen using a Bluetooth headset
and keeping the phone in the
pocket,
consumers can reduce
radiation absorption by
orientating the dial pad toward
the body. http://www.ehow.com/facts_5869977_safe-bluetooth-headsets-brain_.html
