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 10 years or more were more likely to get brain cancer.
The suggestions below may help you reduce the risk (风险) 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 (接触) 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 (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 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.
