Today, the usage of wireless electronic devices are increasing. we are using cell phones, broadband, gps navigation, wifi router, wireless mouse & keyboard, wireless handsfree and etc without knowing that these devices have strong potential to do many kind of damage to us.
This maybe because the supplier never give us warning, what more a precautions. some scientists said they are doing this to maintain the selling of their products but at the same time putting public to a high potential damage.
Most of the devices shown above have similar mechanism, that is they transmit data in micro or radio frequency in the electromagnetic spectrum wavelength. (MF or RF).
Some scientist have discovered that external radio frequency electromagnetic field can make the free radicals in human body stays longer before being neutralized. then this free radicals will have more potential to become reactive oxygen species that can do damage on DNA, RNA and proteins in our body.
The external electromagnetic field is very strong near the antenna of mobile phones, especially during a phone call. Later in this post i will provide the precautions that we should apply to reduce the risk of damage from the MF or RF radiation.
There is also a study from German that found a threefold higher frequency of cancer among people living in the vicinity (400 m) of a GSM base station compared to people living further away from the antenna.
And there are many other studies showed that radio and micro frequency electromagnetic wave will do damage to human. as i took a summary from psrast "A considerable body of evidence proves, beyond reasonable doubt, that microwave radiation from mobile phones and cordless phones cause a significantly increased risk for brain tumors. In addition, increasing evidence is indicating that it causes disturbed brain function, damage to the genes and other disturbances".
Last year, even WHO has changed its statement about this RF and MF radiation. Before, they said RF and MF do not cause any damage to human but around 21.5.2011 they have accepted that radiation from cell phones can possibly cause cancer.The agency now lists mobile phone use in the same "carcinogenic hazard" category as lead, engine exhaust and chloroform.
For us, i think, it is almost impossible to eliminate cell phones from our daily living. this device are really helping us in many aspects. so thing that are practical to be done is we apply the precautions and i hope mobile phone companies can do more research on RF and MF so that the damage can be minimalized.
Here are the precautions provided from a research titled "Risk of Brain Tumors From Wireless Phone Use"
1. Limit the use of cell phones to essential calls and keep
calls short.
2. Children should be allowed to use a cell phone in cases of
emergency only. Because of their developing skulls, the radiation can penetrate much more deeply.
3. Wear an air tube headset (not regular wired headset). The regular wired headset has been found to intensify radia- tion into the ear canal. The wire not only transmits the
radiation from the cell phone but also serves as an an-
tenna, attracting EMFs from the surroundings.
4. Do not put the cell phone in a pocket or a belt while in use or while it is on. The body tissue in the lower body area
has good conductivity and absorbs radiation more quickly than the head. One study shows that men who wear cell phones near their groin could have their sperm count
dropped by as much as 30%.
5. If using the phone without a headset, wait for the call to connect before placing the phone next to the ear.
6. Do not use the cell phone in enclosed metal spaces such as vehicles or elevators, where devices may use more power
to establish connection.
7. Do not make a call when the signal strength is 1 bar or less, which means the phone must work harder to estab-
lish a connection.
8. Purchase a phone with a low SAR. Most phones have a
SAR level listed in its instruction manual.
9. Use a scientifically validated EMF protection device.
There are advanced technologies available nowadays that strengthen the bioenergy field and immune system against the effects of EMF.
10. Use text instead of talk.
11. Use landlines.
12. Keep cell phone off most of the time. Let people leave messages and then call them back from a landline.
13. Limit the use of cell phones in rural areas.
(precautions copied from pdf, and it appeared weird here >.<" . i will edit this later because right now i'm quite busy with the exams)
