Cellphones help us easily find people anywhere at any time. However, using cellphones too often
may cause cancer (癌症). The advice below may help you.
? When using your cellphone, try to keep it away from your body as much as possible. Don't put it under your pillow (枕头）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 with radiation (岸昌射）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 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 (发短信)，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 (信号）is not strong or when moving at a high speed. At high speeds your phone is trying to pick up signals, and this increases (增加）the radiation.
