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.
