All About Cell Phone
More and more people have been using cell phone nowadays. In fact, some
people even consider it as a necessity and we can't blame them. Cell phone
is very useful and helpful for many after all.
What is Cell Phone?
Unless you're living under a rock, you do know what a cell phone is. But

taste, style and need should determine what cell phone you want (not the
sales assistant behind the desk).
The use of "hands-free" was not recommended by the British Consumers'
Association in a statement in November 2000 as they believed that exposure
was increased. However, measurements for the (then) UK Department of Trade
and Industry and others for the French l Agence fran aise de s curit
sanitaire environmental showed substantial reductions. In 2005 Professor
Lawrie Challis and others said clipping a ferrite bead onto hands-free kits
stops the radio waves travelling up the wire and into the head.
Overall Health Risks
Many scientific studies have investigated possible health effects of mobile
phone radiations. These studies are occasionally reviewed by some
scientific committees to assess overall risks. The most recent assessment
was published in 2007 by the European Commission Scientific Committee on
Emerging and Newly Identified Health Risks (SCENIHR). It concludes from the
available research that no significant health effect has been demonstrated
from mobile phone radiation at normal exposure levels:
