Cellphones help us easily find people anywhere at any time.However,using cellphones too often may cause cancer.It's reported that people who used a cellphone for 10years or more were more likely to get brain cancer.
The suggestions below may help you reduce the risk (風險) of cancer:
◆When using your cellphone,try to keep it away from your body as much as possible.Don't put it under your pillow (枕頭)or on a bedside table when you go to sleep.
◆When you're on the cellphone,use the speaker.In this way,you have just 1/100th of the contact(接觸) with radiation you have when you hold it to your ear.An earphone is also a good idea.
◆Try to keep your conversations short.If you need to talk longer,use an ordinary phone instead.
◆Change ears when you're using your cellphone.Before putting it to your ear,wait until the person you are calling picks up the phone.
◆Your phone gives out radiation when you talk or text (發(fā)短信),but not when you're listening or getting messages.Listening more and talking less can lower the risk of cancer.
◆Do not use your cellphone when the signal (信號)is weak or when moving at a high speed,for example in a car or train.At high speeds your phone is trying to pick up signals,and this increases the radiation it gives out.
