1.Do not allow children to use a cell phone, except for emergencies. The developing organs of a fetus or child are the most likely to be sensitive to any possible effects of exposure to electromagnetic fields.

2.While communicating using your cell phone, try to keep the cell phone away from the body as much as possible. The amplitude of the electromagnetic field is one fourth the strength at a distance of two inches and fifty times lower at three feet. Whenever possible, use the speaker-phone mode or a wireless Bluetooth headset, which has less than 1/100th of the electromagnetic emission of a normal cell phone. Use of a hands-free ear piece attachment may also reduce exposures.

3.Avoid using your cell phone in places, like a bus, where you can passively expose others to your phone's electromagnetic fields.

4.Avoid carrying your cell phone on your body at all times. Do not keep it near your body at night such as under the pillow or on a bedside table, particularly if pregnant. You can also put it on “flight” or “off-line” mode, which stops electromagnetic emissions.

5.If you must carry your cell phone on you, make sure that the keypad is positioned toward your body and the back is positioned toward the outside so that the transmitted electromagnetic fields move away from your rather than through you.

6.Only use your cell phone to establish contact or for conversations lasting a few minutes, as the biological effects are directly related to the duration of exposure.
For longer conversations, use a land line with a corded phone, not a cordless phone, which uses electromagnetic emitting technology similar to that of cell phones.

7.Switch sides regularly while communicating on your cell phone to spread out your exposure. Before putting your cell phone to the ear, wait until your correspondent has picked up. This limits the power of the electromagnetic field emitted near your ear and the duration of your exposure.

8.Avoid using your cell phone when the signal is weak or when moving at high speed, such as in a car or train, as this automatically increases power to a maximum as the phone repeatedly attempts to connect to a new relay antenna.

9.When possible, communicate via text messaging rather than making a call, limiting the duration of exposure and the proximity to the body.

10.Choose a device with the lowest SAR possible (SAR = Specific Absorption Rate, which is a measure of the strength of the magnetic field absorbed by the body). SAR ratings of contemporary phones by different manufacturers are available by searching for “sar ratings cell phones” on the internet.

1.不要让孩子使用手机,除非紧急需要。胎儿或者小孩,正处于发育状态的器官对暴露的电磁场最为敏感。

2.当你打电话的时候,设法使手机尽可能的远离身体。电磁场的振幅在两英寸距离强度为1/4,3英尺的距离为1/15。可能的话,尽量使用扬声器模式或者无线蓝牙耳机,它将会小于标准手机辐射的百分之一。使用耳机听筒也可减少辐射。
 
3.避免在某几个地方使用手机,比如公交车,在那儿,你的手机的电磁场将会被动的暴露给他人。

4.避免一直在身上带着手机。不要将它放在身体附近比如枕头底下或者床边的桌子上,尤其对于孕妇。你也可以将其调成“飞行”或者“断开网络连接”模式,因为这将会终止电磁排放。

5.如果你很需要携带手机,设法确保键盘方位朝向你的身体,背面冲着外面,以便电磁场的传播方向驶离你的身体而不是穿过这身体传过去。

6.仅将手机用作于联系或者几分钟的短暂交谈,因为辐射效应会直接与接触时间长短有关。对于长时会话,使用座机而不是无绳电话。其使用的电磁发射信号类似于手机。
 
7.当用手机通话的时候,有规律的换手持手机用来分散辐射。等待对方已经接起电话,在把手机放在耳朵上。这会减少电磁场在你耳边发出的能量和缩短你被辐射的时间。

8.当信号微弱或者高速移动中比如汽车火车,应该避免使用手机。因为它自动将能量增加到最大值,手机会不停的尝试连接到一个新的信号天线中转站。

9.如果可以的话,宁可发短信而不是打电话。这会减少身体的在磁场下的暴露时间和手机与身体的接触。

10.选择一个尽可能的的最低吸收率设备(SAR=Specific Absorption Rate,是一个人体吸收磁场强度的计量单位)。同一代不同制造厂商的手机SAR等级在网络中搜索“SAR等级手机”可查询。
