Naah - not if you get one of the 'wired' ones. It's the *antenna* you've got to keep away from.

There was a study or so that claimed that hands-free kits could give you up to 3x times amount of radiation, but I think they've been discredited. They did weird things like had the 'phones on the test dummy's *shoulder* with the wire alongside the antenna. Those long wires make *lousy* antennas at these high frequencies, anyway.

If you keep the 'phone away from you - there should be no probs. Has your phone not got a built-in 'speaker' mode? That's what I use when I have to use my mobile.

Quote:
Antonia Chitty, of the Consumers' Association, said: "The key factor in whether a hands-free kit increases or cuts radiation is the distance between the tip of the antennae and the earpiece. For one Nokia phone, a difference of four centimetres can alter the effect."


Quote:
Tests by the DTI and the mobile phone industry, which look for specific absorption rates in a head filled with liquid, check the effects of mobile phones, not hands-free kits. They do not specifically measure radiation around the ear and the wire is not allowed to dangle down naturally.

Hands free mobile phone radiation

[Posted: Sun 27/08/2000]

Hands-free kits may cut mobile phone radiation after all, according to the latest research.

Mobile phone users can cut their exposure to radiation if they use hands-free attachments instead of holding the phone to their ear, a recent report has found.

This contradicts earlier research by the UK Consumers' Association which said that hands-free kits acted as aerials, channelling treble the amount of radiation into the users' brain.

Another report by the Australian Consumers' Association found that hands-free kits could reduce the effects of electromagnetic radiation by up to 92%.

Thanks. Then I probably still have a dozen or so working brain cells, to which most here would attest. Wink

Can't use speaker mode most of the time, because I'm either at FOH or backstage during sound checks or performances. Sometimes I can barely hear with the clip in my ear.

Hand free kits only become an antenna if the wire is not shielded so get an expensive one and put a circular magnet around the wire (if you're as paranoid as me!) then RF shouldn't be an issue.




This is better, IMHO. You know those 'ferrite beads' that you see around wires to help stop RF interference? Tape one of those around the wire, close to the ear end, and make sure that your kit's got shielded cable. ie not a $5 one.

If I had to make calls with a ferrite choke hanging from the headset, I'd eventually kill myself with a Vegematic.

My headset is a $30 Plantronics, so it's probably not a shoddy construct. I'll let you know when I hit 70.

I bought a RF3 hands free headset that uses AirCom2 Technology + ferrite bead from Mercola.com. Not a bad device I must say. Not that expensive either.

What do you guys think about the severe penalties for using a mobile phone in the car?
You are allowed to eat,drink,talk with your hands,change radio channels,change cd's,drive with one hand,hold hands with your girl,play with yourself,point at your surroundings,smoke etc, but not talk on your phone because its distracting! Confused

The penalties are too harsh, they say it's because talking on a mobile phone causes too many accidents.

If it's the talking part - what about when you talk to your passengers?! Surely then that is illegal!?!?

and if it's the pushing the button etc - what about when you change the radio or cd etc.


...perhaps there should just be less bad drivers on the road!

Long-term use of mobile phones
'may be linked to cancer'


By Martin Beckford and Robert Winnett - 24 Oct 2009

Long-term use of mobile phones may be linked to some cancers, a landmark international study will conclude later this year.

A 20million, decade-long investigation overseen by the World Health Organisation (WHO) will publish evidence that heavy users face a higher risk of developing brain tumours later in life, The Daily Telegraph can disclose.

The conclusion, while not definitive, will undermine assurances from the government that the devices are safe and is expected to put ministers under pressure to issue stronger guidance.

A preliminary breakdown of the results found a “significantly increased risk” of some brain tumours “related to use of mobile phones for a period of 10 years or more” in some studies.

The head of the Interphone investigation said that the report would include a “public health message”.

Britain’s Department of Health has not updated its guidance for more than four years. It says that “the current balance of evidence does not show health problems caused by using mobile phones”, and suggests only that children be “discouraged” from making “non-essential” calls while adults should “keep calls short”.

In contrast, several other countries, notably France, have begun strengthening warnings and American politicians are urgently investigating the risks.

The Interphone inquiry has been investigating whether exposure to mobile phones is linked to three types of brain tumour and a tumour of the salivary gland.

Its head, Dr Elisabeth Cardis, backed new warnings.

“In the absence of definitive results and in the light of a number of studies which, though limited, suggest a possible effect of radiofrequency radiation, precautions are important,” she said.

“I am therefore globally in agreement with the idea of restricting the use by children, though I would not go as far as banning mobile phones as they can be a very important tool, not only in emergencies, but also maintaining contact between children and their parents and thus playing a reassurance role.

“Means to reduce our exposure (use of hands-free kits and moderating our use of phones) are also interesting.”

The project conducted studies in 13 countries, interviewing tumour sufferers and people in good health to see whether their mobile phone use differed. It questioned about 12,800 people between 2000 and 2004.

Previous research into the health effects of mobile phones, in the short time they have been in use, has proved inconclusive. However, a breakdown of the latest findings, seen by The Daily Telegraph, shows that six of eight Interphone studies found some rise in the risk of glioma (the most common brain tumour), with one finding a 39 per cent increase.

Two of seven studies into acoustic neurinoma (a benign tumour of a nerve between the ear and brain) reported a higher risk after using mobiles for 10 years. A Swedish report said it was 3.9 times higher.

A summary said a definitive link could not be proved because of difficulties with subjects’ memories.

An Israeli study found heavy users were about 50 per cent more likely to suffer tumours of the parotid salivary gland.

The Interphone inquiry has faced criticism for including people who made just one call a week, and leaving out children, which some experts said could underplay the risks. Some results for short-term use appeared to show protection against cancer, suggesting flaws in the study.

The final paper, funded partly by the industry, has been delayed as its authors argued over how to present the conclusions. But it has been sent to a scientific journal and will be published before the end of the year.

A spokesman for the Health Protection Agency said there was “no hard evidence at present” of harm to health. Use by children for non-essential calls should be discouraged, he added.

A spokesman for the Mobile Operators Association said more than 30 scientific reviews had found no adverse health effects.

Cell Phone Radiation Is Actually Not Bad For Us Now, It Prevents Brain Disorders

http://preventdisease.com/news/10/010710_cell_phone_radiation_not_bad_now.shtml

Marco Torres is a research specialist, writer and consumer advocate for healthy lifestyles. He holds degrees in Public Health and Environmental Science and is a professional speaker on topics such as disease prevention, environmental toxins and health policy.

Yet another ridiculous study out of the University of South Florida claims that cell phone radiation actually protects against brain disorders rather than cause them.

Its another version of researchers promoting junk science at its best. The ludicrous study only done in mice, suggests that long-term exposure to electromagnetic frequencies (EMF) associated with cell phones may actually protect against, and even reverse, Alzheimers disease.

It surprised us to find that cell phone exposure, begun in early adulthood, protects the memory of mice otherwise destined to develop Alzheimers symptoms, said lead author Gary Arendash, PhD, USF Research Professor at the Florida ADRC. It was even more astonishing that the electromagnetic waves generated by cell phones actually reversed memory impairment in old Alzheimers mice.

The so-called researchers claim their study was highly-controlled and that they isolated the effects of cell phone exposure on memory from other lifestyle factors such as diet and exercise. Yes folks, were talking about the lifestyle factors of mice, but you can see where this is going.
So how did they achieve this magnificent feat you ask? Well, when scientists cant get the results they want from animal testing, they genetically alter animals to achieve favorable results. This way, the biology of their lab rats is custom tailored to suit the objectives and conclusions desired by the scientists and their funding sources. Its actually very common and this study is no different.

It involved mice, most of which were genetically altered to develop beta-amyloid plaques and memory problems mimicking Alzheimers disease as they aged. Think about what would happen if you radiated a genetically modified potato that was designed to be different than a potato found in nature. The cells of the genetically modified (GM) potato could react very differently from the natural potato to a given stimulus. They may be more susceptible or resistant to the radiated dose depending on how the GM potato was designed specifically for that purpose. The same principal can be achieved with rodents.

The conditions of the experiment were also simulative as no practical application on mice could ever mimic how humans use phones. The mice didnt wear tiny headsets or have scientists holding cell phones up to their ears; instead, their cages were arranged around a centrally-located antenna generating the cell phone signal.

But wait, the researchers claim that they perfectly housed each mouse the same distance from the antenna and exposed them to electromagnetic frequencies typically emitted by a cell phone pressed up against a human head. Huh? They exposed tiny little mice to the same EMF as cell phones emitted to a human head? Wouldnt that expose the mice to a lopsided amount of EMF comparatively by ratio if you were to quantify the head mass of a human and that of a mouse? Okay, perhaps they overlooked that this wouldnt be very applicable to humans.
Or maybe not. They stated they used memory tests on the mice that were closely designed from a sensitive test used to determine if Alzheimers disease, or its very early signs (mild cognitive impairment), are present in humans. Since we selected electromagnetic parameters that were identical to human cell phone use and tested mice in a task closely analogous to a human memory test, we believe our findings could have considerable relevance to humans, Arendash said. Hmmm, so Arendash is suggesting that a sensitive test used to determine a complex human brain disorder like Alzheimers, can be reproduced in rodents? I would love to see that test.

They found that if cell phone exposure was started when the genetically-programmed mice were young adults before signs of memory impairment were apparent their cognitive ability was protected. Months of cell phone exposure even boosted the memories of normal mice to above-normal levels. The memory benefits of cell phone exposure took months to show up, suggesting that a similar effect in humans would take years if cell phone-level electromagnetic exposure was provided.

Are you starting to get the picture of how absurd this study and its objective is? Perhaps we could genetically alter humans now so they could boost their memory, protect their cognitive ability and prevent brain disorders, all from a few years of dedicated cell phone use.

Based on what the researchers claim are promising and unexpected findings in mice, they concluded that electromagnetic field exposure could be an effective, non-invasive and drug-free way to prevent and treat Alzheimers disease in humans. Wait, it gets better. They are also now evaluating whether different strengths of electromagnetic frequencies will produce a faster and even greater cognitive benefit. So the stronger the EMF the greater the benefit? I wonder if the heat in Florida makes researchers go nutty?

The researchers also found increases in brain temperature during the two one-hour periods when mice were exposed to electromagnetic waves each day. This increase in brain temperature was seen only in the Alzheimers mice, and only after months of exposure. So the normal mice didnt have a increase in brain temperature after months of blasting them with high EMF doses? Those were some amazingly resilient normal mice.
Our study provides evidence that long-term cell phone use is not harmful to the brain, Dr. Cao said. To the contrary, the electromagnetic waves emitted by cell phones could actually improve normal memory and be an effective therapy against memory impairment.

I think Dr. Cao said it all. Improving memory and effective therapy against impairment.who could ask for more right?

This is one of the most obviously senseless, illogical and foolish studies I have ever seen. Not only is the construct of the study absurd, but the researchers discussions and conclusions are so outlandish and unsupported, that they make global warming studies actually look scientific.

I find it very suspicious that not even one of these authors had a disclosure statement.

Another disturbing fact was that this study was supported by Byrd Alzheimers Institute.

This is an obvious attempt by the cell phone industry to further warp (literally) and sway public opinion on the detrimental health effects of cell phone radiation which are increasingly catching the medias attention.
Electromagnetic frequencies and radiation are emerging health problem of the 21st century.

Cells in the body react to EMFs as potentially harmful, just like to other environmental toxins, including heavy metals and toxic chemicals, said Martin Blank, PhD.

Based on the existing science, many public health experts believe it is possible we will face an epidemic of cancers in the future resulting from uncontrolled use of cell phones and increased population exposure to W-iFi and other wireless devices.

Thus it is important that all of us, and especially children, restrict our use of cell phones, limit exposure to background levels of Wi-Fi, and that government and industry discover ways in which to allow use of wireless devices without such elevated risk of serious disease, said David Carpenter, MD.

Radio frequency radiation and other forms of electromagnetic pollution are harmful at orders of magnitude well below existing guidelines, said Magda Havas, PhD.

The overall problem with environmental electromagnetism is much deeper, not only of concern at power line frequencies, but also in the radio frequency range encompassing mobile phones.
Here the public's continuing exposure to electromagnetic radiation is largely connected to money.

Indeed the tens of billions of dollars in sales one finds in the cell phone industry makes it mandatory to corporate leaders that they deny, in knee-jerk fashion, any indication of hazard, said Abraham R. Liboff, PhD .

Next theyll be telling us that cell phone radiation can increase your income, boost your love life and make you fly.

Cell Phone Exposure May Protect Against and Reverse Alzheimer's Disease


http://www.sciencedaily.com/releases/2010/01/100106193217.htm

ScienceDaily (Jan. 7, 2010) The millions of people who spend hours every day on a cell phone may have a new excuse for yakking. A surprising new study in mice provides the first evidence that long-term exposure to electromagnetic waves associated with cell phone use may actually protect against, and even reverse, Alzheimer's disease. The study, led by University of South Florida researchers at the Florida Alzheimer's Disease Research Center (ADRC), was published January 6 in the Journal of Alzheimer's Disease.

"It surprised us to find that cell phone exposure, begun in early adulthood, protects the memory of mice otherwise destined to develop Alzheimer's symptoms," said lead author Gary Arendash, PhD, USF Research Professor at the Florida ADRC. "It was even more astonishing that the electromagnetic waves generated by cell phones actually reversed memory impairment in old Alzheimer's mice."

The researchers showed that exposing old Alzheimer's mice to electromagnetic waves generated by cell phones erased brain deposits of the harmful protein beta-amyloid, in addition to preventing the protein's build-up in younger Alzheimer's mice. The sticky brain plaques formed by the abnormal accumulation of beta amyloid are a hallmark of Alzheimer's disease. Most treatments against Alzheimer's try to target beta-amyloid.

The highly-controlled study allowed researchers to isolate the effects of cell phone exposure on memory from other lifestyle factors such as diet and exercise. It involved 96 mice, most of which were genetically altered to develop beta-amyloid plaques and memory problems mimicking Alzheimer's disease as they aged. Some mice were non-demented, without any genetic predisposition for Alzheimer's, so researchers could test the effects of electromagnetic waves on normal memory as well.

Both the Alzheimer's and normal mice were exposed to the electromagnetic field generated by standard cell phone use for two 1-hour periods each day for seven to nine months. The mice didn't wear tiny headsets or have scientists holding cell phones up to their ears; instead, their cages were arranged around a centrally-located antenna generating the cell phone signal. Each animal was housed the same distance from the antenna and exposed to electromagnetic waves typically emitted by a cell phone pressed up against a human head.

If cell phone exposure was started when the genetically-programmed mice were young adults -- before signs of memory impairment were apparent -- their cognitive ability was protected. In fact, the Alzheimer's mice performed as well on tests measuring memory and thinking skills as aged mice without dementia. If older Alzheimer's mice already exhibiting memory problems were exposed to the electromagnetic waves, their memory impairment disappeared. Months of cell phone exposure even boosted the memories of normal mice to above-normal levels. The memory benefits of cell phone exposure took months to show up, suggesting that a similar effect in humans would take years if cell phone-level electromagnetic exposure was provided.

Based on their promising and unexpected findings in mice, the researchers concluded that electromagnetic field exposure could be an effective, non-invasive and drug-free way to prevent and treat Alzheimer's disease in humans. They are currently evaluating whether different sets of electromagnetic frequencies and strengths will produce more rapid and even greater cognitive benefits than those found in their current study.

"If we can determine the best set of electromagnetic parameters to effectively prevent beta-amyloid aggregation and remove pre-existing beta amyloid deposits from the brain, this technology could be quickly translated to human benefit against AD" said USF's Chuanhai Cao, PhD, the other major study author. "Since production and aggregation of β-amyloid occurs in traumatic brain injury, particularly in soldiers during war, the therapeutic impact of our findings may extend beyond Alzheimer's disease."

The memory test used to evaluate the effects of cell phone exposure in mice was closely designed from a sensitive test used to determine if Alzheimer's disease, or its very early signs (mild cognitive impairment), are present in humans. "Since we selected electromagnetic parameters that were identical to human cell phone use and tested mice in a task closely analogous to a human memory test, we believe our findings could have considerable relevance to humans," Arendash said.

The researchers found a slight increase in brain temperature during the two one-hour periods when mice were exposed to electromagnetic waves each day. This increase in brain temperature was seen only in the Alzheimer's mice, and only after months of exposure. The researchers suggest the increase in brain temperature helped the Alzheimer's brain to remove newly-formed beta-amyloid by causing brain cells to release it.

The researchers were particularly surprised to discover that months of cell phone exposure actually boosted the memory of non-demented (normal mice) to above-normal levels. They suspect that the main reason for this improvement involves the ability of electromagnetic exposure to increase brain activity, promoting greater blood flow and increased energy metabolism in the brain. "Our study provides evidence that long-term cell phone use is not harmful to brain," Dr. Cao said. "To the contrary, the electromagnetic waves emitted by cell phones could actually improve normal memory and be an effective therapy against memory impairment."

"It will take some time to determine the exact mechanisms involved in these beneficial memory effects," Arendash said. "One thing is clear, however -- the cognitive benefits of long-term electromagnetic exposure are real, because we saw them in both protection- and treatment-based experiments involving Alzheimer's mice, as well as in normal mice."

Previous human studies of electromagnetic waves from cell phones involved only brief exposures given to normal humans. While some studies reported small improvements in attention or memory (not enough to impact daily life), others reported no memory effects from short-term exposure. The new study by Arendash, Cao, and their colleagues is the first to investigate the effects of long-term electromagnetic exposure over many months on memory function in either humans or animals. The findings indicate that "long-term" exposure to cell phone level electromagnetic waves is needed to observe enhanced memory in normal or memory-impaired mice.

The USF researchers began investigating the effects of cell phone use on Alzheimer's disease several years ago, after several observational studies in humans linked a possible increased risk of Alzheimer's with "low-frequency" electromagnetic exposure -- like the energy waves generated by power and telephone lines. However, cell phones emit "high-frequency" electromagnetic waves, which are very different because they can have beneficial effects on brain cell function, such as increasing brain cell activity, Arendash said.

There has been recent controversy about whether electromagnetic waves from cell phones cause brain cancer. Some researchers argue that the risk of glioma (40 percent of all brain tumors) doubles after 10 or more years of cell phone use. However, others argue that since the overall lifetime risk of developing a brain tumor of any type is less than 1 percent, any doubling of this risk would still be very low. Groups such as the World Health Organization, the American Cancer Society, and the National Institutes of Health, have all concluded that scientific evidence to date does not support any adverse health effects associated with the use of cell phones. Consistent with the view of these organizations, the researchers found no autopsy evidence of abnormal growth in brains of the Alzheimer's mice following many months of exposure to cell phone-level electromagnetic waves. They also found all major peripheral organs, such as the liver and lungs, to be normal.

The research was conducted by an interdisciplinary group of neuroscientists, electrical engineers, and neurologists from universities in Japan and China as well as from the Florida ADRC at the University of South Florida. The study was supported by funds from the Florida ADRC, a statewide project sponsored by the National Institute on Aging, and the USF Health Byrd Alzheimer's Institute.
