Precautions while using a cell phone
Now a days people are using cell phone for exchanging ideas and communicate with others.They talk about their life with their friends and relatives and with their business associates they like to get information about deals,new projects and market. The cell is helpful for us on the one side and also release electromagnetic radiations which are harmful for our health.
So at the time a person is using cell phone he should keep on mind some points.Which are:
1. Allow children to use a cell phone only when theree is an 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. If you are using a cell phone for communication, 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.
3. . Whenever possible, use the speaker-phone mode or a headset, which has less than 1/100th of the electromagnetic discharge of a normal cell phone. Use of a hands-free ear piece attachment may also reduce exposure.
4. . Avoid using your cell phone in public places, like a bus, where you can passively expose others to your phone’s electromagnetic fields.
5. If you are pregnant,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. You can also put it on “airplane” or “off-line” mode, which stops electromagnetic emissions.
6. If it is necessary to you carry your cell phone with 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.
7. As the biological effects are directly related to the duration of exposure so only use your cell phone to establish contact or for conversations lasting a few minutes. For longer conversations, use a land line with a corded phone, not a mobile phone, which uses electromagnetic emitting technology similar to that of cell phones.
8. 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.
9. When the signal is weak or moving at high speed ,avoid using your cell phone. Such as: while traveling this automatically increases power to a maximum as the phone repeatedly attempts to connect to a new relay antenna.
10. When possible, communicate via text messaging rather than making a call, limiting the duration of exposure and the closeness to the body.
11. 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.
