Are Cellphones not a safety device?

As you answer yourself this question, pay attention to each of the ten points argued about precautions we should consider while using a cellphone.

Read the article and in groups of three discuss your point of view towards the article.

Number and explain the points in which you agree with and the ones in which you disagree and explain them to the group.

The Ten Precautions of Cell Phone Use
Recommendations for cell phone use that affects not just children but all users from theEnvironmental Health Trust:

Given the absence of definitive proof in humans of the carcinogenic effects of electromagnetic fields of cell phones, we cannot speak about the necessity of preventative measures (as for tobacco or asbestos). In anticipation of more definitive data covering prolonged periods of observation, the existing data press us to share important prudent and simple measures of precaution for cell phone users, as have been variously suggested by several national and international reports.
These measures are also likely to be important for people who are already suffering from cancer and who must avoid any external influence that may contribute to disease progression.

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 headset attachment may also reduce exposure.
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, it is preferable that the keypad is positioned toward your body and the back is positioned toward the outside of your body. Depending on the thickness of the phone this may provide a minimal reduction of exposure.
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.
CONCLUSION
The cell phone is a remarkable invention and a breakthrough of great social importance. Our society will no longer do without cell phones. None of the members on the expert committee has stopped or intends to stop using cell telephones. This includes Dr. David Servan-Schreiber, a 16 year survivor of brain cancer. However, we, the users, must all take precautionary measures in view of recent scientific data on the biological effects of cell phone use, especially those who already have cancer.
In addition, manufacturers and service providers must also assume responsibility. It is their responsibility to provide appliances and equipment with the lowest possible risk and to constantly evolve their technology in this direction. They should also encourage consumers to use their devices in a way that is most compatible with preserving their health.
In the early 1980’s, the owners of asbestos mines were reduced to bankruptcy as a result of lawsuits brought by the families of deceased exposed workers. A few years later, a key executive of Johns Manville, the most prominent company, drew lessons from the years of struggle of his industry against medical data and the scientists who were drawing attention to the risks of asbestos. He concluded with regret that greater warnings for the public, the establishment of more effective precautions, and more extensive medical research "could have saved lives, and probably also shareholders, the industry, and the benefits of its product.”
We call on the cell phone companies to provide independent access to records of use so that appropriate studies can be carried out.
That is what we wish for today's cell phone industry. We do not need to ban this technology, but to adapt it – to harness it – so that it never becomes a major cause of illness.

    -Are celphones electromagnetic emissions really bad for your health?
    -Why people use this danger danger device?
    -Why people in general dont know about this situation?
    - In wich way can we inform the rest of the population?
    -Do you know the consequences of using a phone in public places?

    Are communicate via text messaging is better than making a call?
    Does bluetooth is more dangerous than keeping your pone next to your ear?
    Kepping your phone under your pillow when are sleeping is a great idea?
    Is better to avoid using your cellphone on a bus so you don’t expose others?
    Is bad using your cell phone when the signal is weak or when moving at high speed?
