Intensive testing has been undertaken, and long term tests are still being performed. Current thinking is that modern mobile handsets cannot harm the human body, although in the interests of caution, you are advised not to let young children or babies use such devices (as the bones are still soft, they could be more susceptible).\n\nTests on mice and rats have shown tumour growth when subjected to prolonged exposure to the type of radiation produced by mobile phones, but only when the level is much higher than modern mobile phones (about 5x more!) and the duration much longer than would normally be present.\n\nAlso, modern digital mobile phones only produce harmful radiation when in use (i.e. when surfing or calling) or when reporting position to the network (about once every 15-45 minutes depending on network setup). \n\nThe new generation of mobile phones (3G) use a different type of digital transmission and power control is much more important than was the case for the older phones, so the level of radiation should be much reduced again.\n\nThere has been no reports of heart attack or cardiac disturbance from mobile phone use, the only dangers are over-heating / exploding when being charged or used excessively but needless to say these effects are extremely rare.\n\nSo, I would say there is no danger in keeping a mobile phone in a shirt pocket - in fact, I do!

WebMD is a good website.  However, it is NOT true that only doctors can have an informed opinion on this.  I am a research biologist who studies cancer in my laboratory.  So, I think my opinion is valid even though I am not a Medical Doctor.  Please see my answer on your previous question for a more thorough explanation of the causes of cancer.\n\nRadiation is known to induce mutations, which can then result in cancer.  However, it is NOT clear whether the radiation dosage from power lines or cell phones is sufficient to cause cancer.  I suspect it is NOT or else we would be experiencing a cancer epidemic in America.

Yes, the radiation from cancer treatments is very dangerous, but the radiation is directed in such a way that is that it will be more damaging to the cancer cells than to healthy cells.

in order to receive a damaging amount or radiation you would need about 600 full power chest xrs in a year so it is extrememly unlikely that there will be residual effects

I have read of research that shows that using a phone while driving is equally as dangerous as a .05 blood alcohol reading. Those phone users really annoy me .

No, it's FAR too low energy to cause such problems.\n\nA high energy source, such as a microwave oven of mobile phone mast has the hind of power required to alter DNA structure and cause cancer.  Various studies hint that a mobile phone will do it with prolonged use as well.

I don't think that it should be.  I often talk on the phone to actually stayed focus on driving, I get distracted by things in my purse, or playing with my hair, or the radio, ect... being on the phone keeps me focused on the road while my hand holds the phone to my ear.  People always know that I am on and know not to be insulted if the call ends abruptly.  I only use it responsibly and mostly for long distance driving. I have been in many more accidents than I would like to admit, and not one occured while I was on the phone!!  I've had more close calls without the phone than with also.\n\nCell phones are also excellent for helping people know where they are driving in areas that they are unfamiliar with.

Microwaves are highly targetable, that is their primary benefit. Microwaves were developed for use with radar, thus early microwaves were called radar ranges.\nThat being said, there will always be a little leakage, not enough to be dangerious, at least no more dangerious that the other megajoules of microwaves coursing through your body thoughout the day from radars, radar detectors, alarm systems communications arrays, etc.

A Swedish study finds that users of digital phones in rural areas may be at greater risk of brain cancer. Its authors say the link is troubling, although they acknowledge that the amount of data is small and wider research is needed to amplify the findings.\n\nThe researchers said that incidence of brain tumors in rural areas of Sweden was much higher among users of GSM cell phones than among rural residents who were not cell phone users. The rate was also higher than among GSM users in urban areas.\n\nThe chance of developing a malignant brain tumor was roughly eight times higher for cell phone users in the Swedish countryside than in urban areas. The risk of developing any brain tumor was four times higher for country dwellers using mobile phones for five years or more, compared with those who did not use the devices.\n\nThe study suggests that mobile handsets in rural areas deliver a higher dose of electromagnetic radiation because they have to transmit a stronger signal to distant transmission towers, whereas towers are closer together in urban areas, resulting in phones transmitting a weaker signal.\n\nResearchers looked at more than 1,400 adults aged 20 to 80 who had been diagnosed with a malignant or benign brain tumor between 1997 and 2000. The brain cancer patients were compared with a similar number of healthy adults living in the same area. Each group was asked to recall their daily use of mobile and cordless phones.\n\n"Clearly our results support the notion that exposure may differ between geographical areas," Hardell said. "But there is no information on the exact difference between geographical areas."

According to one teen in London, definately no.\n\n"==\nIn the British Medical Journal, they highlight the case of a teenager left with severe injuries after being struck by lightning when talking on her phone.\n\nThe metal in the phone directs the current into the body, they say.\n\nA 15-year-old girl was struck by lightning while talking on her phone in a large park in London during stormy weather. \n\n...\n\nWhen a person is hit by lightning, the high resistance of human skin causes the lightning charge to flows over the body - often known as an 'external flashover'.\n\nBut some of the current can flow through the body. The more that flows through, the more internal damage it causes.\n\nConductive materials in direct contact with the skin such as liquid or metal objects increases the risk that the current will flow through the body and therefore cause internal injury. \n=="\n\nSo, best thing to do when your in a thunderstorm is to hold off calling your friends to tell them. Well, that and get inside.

Microwaves do emit radiation, but, true to their name, the radiation is in the form of micro-waves.  These waves lack the power to penetrate skin.  \n\nThe heat is of a worse danger, as testicles require a temperature lowere than that of the rest of the body, but I doubt that that is a concern so long as the door is closed and you yourself are not directly within the source of heat.  \n\nEven with that concern, men produce so much sperm each day that it is unlikely that you would be rendered infertile.\n\nI do believe that your reproductive future is safe.

Well first of all no governments can read peoples' thoughts so it's not that big a worry in the real world.\n\nBut if they could do so by electromagnetic radiation (or cause you to think other things) then the only way to protect yourself would be to go into a faraday cage.  If your entire body were covered in tin (more likely aluminium if you use the 'tin foil' that you buy in shops) then you would be in one (a wire mesh will often work fine too due to the radiation 'seeing' a wire mesh with spacing less than half a wavelength as solid).\n\nBut if you just cover your head then you won't actually stop the EM radiation very well (and might end up focusing it towards your brain).

Its said that cell phones.. When you're blabbing away on your cell phone, did you know that your voice is transmitted from the antenna as radio frequency radiation? In fact, your voice puts out about half as much radiation as a microwave. Too bad we can't cook up a meal simply by talking to it on our cell phone.\n\nIt shouldn't come as a surprise that with that much radiation flowing from your phone, there's a good chance it's going to soak into your brain and cause some kind of damage. Cell phone users are at risk for getting rare brain tumors. In fact, studies have found that the rare tumors happen on the same side of the head that people usually use to talk on their cell phones.\n\nMillions of people use their cell phone on a daily basis - America alone has about 123 million cell phone users. Are you one of them? If so, you are putting a high-powered transmitter against your head - about an inch away from your brain. So don't sound so shocked to hear that talking on your cell phone might cause some serious damage.

Its no more dangerous than using your home computer.  There are microwaves emmitting from everything from your monitor to your tv to your microwave oven to portable phones.  If you use those things and have no reactions then you will have no reactions to wifi either.

MRI scans are performed in a very strong magnetic field.  There is no conclusive proof, but it is generally felt that exposure to strong magnetic fields generated by MRI scanners is harmless to humans.  That being said, however, there are some theoretical risks.  Without getting too technical, MRI images are generated by rapid variations in the magnetic field.  These variations cause the water protons within the body to behave a certain way, which in turn generate very minute signal which can be picked up by special receiver coils that make up part of the MRI scanner.  These signals are then processed by the scanner, and and image is generated.  The rapid shifts in magnetic fields can theoretically produce heat as a by-product.  This is especially true for any metallic object within the scanner that has the shape of a ring or closed loop.  In fact, this can produce enough heat in conventional MRI scanners to cause flesh burns.  This is one reason why all metal must be removed before getting an MRI scan.  The actual magnetic field itself is probably safe.\n\nAs for PET scans, the physics is entirely different.  PET scans generate an image by radioactive emissions that are produced in the body after getting injected with radioactive material.  The PET scanner itself is really nothing but a giagantic receiver device to detect these emission.  While the actual dose of radiation from a PET scan is felt to be reasonably safe, it is still radiation nonetheless.  The more PET scans you have, the more radiation you will be exposed to.  But there is no danger to just lying in the scanner itself without getting injected with the radioactive isotope because the scanner itself does not generate actual radiation.

As far as personnall information on a cell phon eit depends on what u mean as far as ur information stored in your cell phone yes it is safe, safe from poeple using your phone the answer is no so that is why u shouldn't let poeple use your phone!

There is a huge difference between ionizing and non-ionizing radiation.  RF radiation is non-ionizing and unless you have such high levels that you could be burned by it, there is no inherent danger - just keep below the ANSI levels.  There have been tons of epidemiological tests which show that there is no causality to cancer.  Remember that light is another source of non-ionizing radiation and people don't seem too concerned about being 'bombarded' by it.
