for how much time can we talk on cell phones without hurting ourselves?

Question

i mean from cancer etc.

Answer 1

Again, this is another unproven myth that is out there in the world today. Cell phones operate at a frequency of about 850-1900mghz. This operates in the RF spectrum of radiation. This is also on the low end of the RF Spectrum. This is non-ionizing radiation levels, unlike that of medical equipment like X-Rays.

RF can be harmful at high enough levels, like that of a microwave oven, and say you stuck your head in it, then turned it on and left it there for several minutes. Since cell phones operate at a frequency much lower then Microwave ovens, I think there is a very low risk.

In cell phones, what produces the most amount of heat, or RF energy, is the antenna. Plus RF signal loses its strength the further you get away from the source. So the further away you are from the antenna, the less frequency. The less frequency, the less heat, then the less chances of over heating your cells, causing cell mutations, and then leading to cancer.

My first question would be do you use a microwave oven, watch tv, listen to the radio, or have an IPod? If you do, then I am sure you really aren't all that worried about RF Frequency and its chance of causing cancer. Since all of these devices produce it. So do key cards at a grocery store, Id cards into work, and massive amounts of other thngs in our everyday life.

There have been no clinical trials or studies that have proven the small amount of Rf from cell phones to cause cancer.

Answer 2

This is very difficult to answer, since it has NEVER been medically proven that cell phones cause cancer anyway. It's being studied more and more everyday but there are no conclusive studies indicating that it absolutely causes cancer. Just theories relating to it is all. If you feel afraid of that then you should make up your own rules for being on your cell phone. Whatever you are comfortable with should work for you. Otherwise, you shouldn't worry about something that has never been proven. Don't worry over something that may never happen. Good luck!

Answer 3

''A few studies suggested a link with certain rare types of brain tumors, but the consensus among well-designed population studies is that there is no consistent association between cell phone use and brain cancer.
Consumers could easily have missed the reports showing no danger from cell phones because they didn't receive alarming front-page coverage like the original reports. What has been proven is that using a cell phone while driving increases the risk of having a car accident. So, keeping your hands free and your eyes on the road is a more significant issue for people who use cell phones.''

Answer 4

See I hate this....There will always be a study that will find you can get cancer from just about anything in this world. You and I probabley eat food on a daily basis that "could" cause cancer.
I say F it all. Do what you want to do when you want to do it for as long as you want to. You don't need anyone else telling you what you should do. Live life and have no regrets.

Answer 5

There is no specific time, but the longer you use the phone the greater the advers affects and certainly use of phones by young children should be avoided altogether, due to their skull and brauin is still developing. All in all this is a valid concern and you may want to consider the following;
Although there is no proof to indicate that mobile phones can cause cancer, there is sufficient debate to cause doubt as to the relative safety. The thing is, it is a mutlibillion dollar industry and it will not be quashed without definite proof, which may not arise for some decades. As a telecommunications engineer I am aware of the poower density levels produced by mobile phones and the effect they can have on different people.
Mobile phones transmit using radio frequency radiation (RFR). Dependant on the network this can range between 800MHz and 2GHz. These are radio waves located within the electromagnetic spectrum. X-rays which are known to cause cancer through ionizing radiation are also within the electromagnetic spectrum, however, RFRs cannot cause cancer in the same way as x-rays because RFRs are non-ionizing.

However, high levels of RFRs can cause health effects through heating the human body (thermal effects). To address this health effect, the Radiocommunications (Electromagnetic Radiation Human Exposure) Standard 1999 specifies limits on public exposure to RF radiation from mobile phones. The limits set by this Standard are only a fraction of the levels needed to cause thermal effects.

Whilst it cannot be shown at this point in time that the thermal effects from mobile phones are a health hazard there is a considerable body of scientific literature which describes the effects of RFR in biological systems that cannot be directly attributed to heating. These effects are referred to as non-thermal and have been demonstrated to cause alteration in animal behaviour, or changes in the functioning of cell membranes.
Digital mobile phones peak power outputs typically correspond to 2 Watts or 2000 milliwatts (mW) which averages to 250 mW of continuous power. The old analogue phones (AMPS system) has peak power limited to 600mW.

The higher power of 2W equates to a SAR (Specific Absorption Rate) of 4W/kg. (= 25mW/sq cm.) Max. allowable as identified in AS-2772 is 200microwatts/square cm. (But this standard does not apply for devices emmitting less than 7W!! Why so?? Although this transmitted level is considerably more that the standard it is only for a short time and the average power level of 250mW would be more applicable, which would result in a level of approx. 3microwatts/sq cm, considerably less than that identified in AS-2772.
As such the scientific basis for assuming there is insufficient evidence for a health hazard is primarily due to the following criteria;
- There is no evidence of a dose response curve.
- There is no known plausible biological mechanism for RFR to cause cancer or other diseases at the levels found with mobile phones.
- The scientific literature on RFR exposure and health effects is inconsistent.

What does this all mean? Well in conclusion, I believe that mobile phones may have some adverse effects, but as it cannot be scientifically proven at present I would suggest that if you are concerned you should;
- Limit the prolonged use of mobiles to under a couple of minutes at a time.
- Use the phone in handsfree speaker mode.
- Avoid using the phone in a confined space (such as in the car or building) as this causes the phone to radiate at the higher power levels to get a signal out.
Personnaly I avoid using the phone as much as possible and if I need to use it I keep it under a few minutes or use hands free.

Answer 6

It depends upon the cell phone. Good Quality.

Answer 7

Who knows?

There have been no conclusive studies done.

There has been SUGGESTION that mobile phone usage could be linked to brain tumour, so use an earphone and remote mike if you are worried, or limit your call times.

Answer 8

i've got made it the 1st 30 years of my life without an digital leash...er, I advise...without a "cellular telephone". Haha... with the intention to respond to your different questions: it is not significant to me the least bit. actually, i don't prefer one. cellular telephones tend to be stressful and a great form of of their proprietors tend to be obnoxious. I also have a telephone in my homestead...that is purely advantageous.

Answer 9

As much as you need.

New phones are very safe.

Most people if not in habit will get soar throat, and other pains associated with constant talking and listening.

Answer 10

less than 10 minutes
