A number of countries have started looking at the dangers linked
with cellphone radiation and have started setting standards for
the usage of the phones. Some countries ban the use of these
phones in public places like trains. Some medical experts
believe that radiation from cell phones is more dangerous than
cigarette smoke, because of the wider use of these appliances;
however, there is not scientific consensus about how much danger
a cell phone can actually cause. The amount of cell phone use
could be a factor, as well as using a physically-damaged cell
phone that needs repair. The Dangers Involved The operation of
cell phones involves using electromagnetic radiation from the
microwave region in this spectrum. This radiation is absorbed by
the human body and thus users of cell phones are constantly
exposed to such radiation. The amount of radiation that is
emitted by a cellphone will depend on its model. Such radiation
is measured as a Specific Absorption Rate, and safe levels are
those below 1.6. W/kg of
