Cell Phones : Hang Up or Keep Talking?
Millions of people are using cell phones today.In many places it is actually considered unusual not to
use one.In many countries,cell phones are very popular with young people.They find that the phones are
more than a means of communication一having a mobile phone shows that they are cool and connected.
The explosions around the world in mobile phone use make some health professionals worried.Some
doctors are concerned that in the future many people may suffer health problems from the use of mobile
phones.In England,there has been a serious debate about this issue. Mobile phone companies are worried about
the negative publicity of such ideas.They say that there is no proof that mobile phones are bad for your health.
On the other hand,why do some medical studies show changes in the brain cells of some people who use
mobile phones?Signs of change in the tissues of the brain and head can be detected with modern scanning
equipment. In one case,a traveling salesman had to retire at a young age because of serious memory loss.He
couldn't remember even simple tasks.He would often forget the name of his own son.This man used to talk
on his mobile phone for about six hours a day,every day of his working week,for a couple of years. His family
doctor blamed his mobile phone use,but his employer's doctor didn't agree.
What is it that makes mobile phones potentially harmful?The answer is radiation.High-tech machines
can detect very small amounts of radiation from mobile phones.Mobile phone companies agree that there is
some radiation,but they say the amount is too small to worry about.
As the discussion about their safety continues,it appears that it's best to use mobile phones less often.
Use your regular phone if you want to talk for a long time.Use your mobile phone only when you really need
it. Mobile phones can be very useful and convenient,especially in emergencies.In the future,mobile phones
may have a warning label that says they are bad for your health.So for now,it's wise not to use your mobile
phone too often.On the safety issue of mobile phones,the manufacturing companies_________.A:deny the existence of mobile phone radiationB:develop new technology to reduce mobile phone radiationC:try to prove that mobile phones are not harmful to healthD:hold that the amount of radiation is too small to worry about
