Another cell phone study, this one out of Turku, Finland, has revealed that cell phone use does, in fact, affect the brain. A significant finding amid the controversy surrounding the extremely popular devices.
PET measurements were taken on 13 young, healthy males who were exposed to the GSM signal for 33 minutes each, explained Science Daily. The study confirmed that glucose metabolism in the temporoparietal and anterior temporal areas of the brain hemisphere closest to the device’s antenna becomes suppressed by GSM mobile telephone electromagenetic fields, said Science Daily.
The study, initiated by Centre for Cognitive Neuroscience (CCN) at University of Turku, was described as methodologically unique in that it used both proficiency in brain imaging via the National PET-Center and CCN; measurements and modeling of radiation via the Radiation and Nuclear Safety Authority in Finland, STUK; and measurements of skin temperature taken by the Finnish Institute of Occupational Health, TTL, noted Science Daily.
And, while definitive health risk conclusions could not be made, the study does indicate another way in which cell phones affect the brain. Study results appear in the Journal of Cerebral Blood Flow & Metabolism.
Recently, writing that the World Health Organization’s (WHO) International Agency for Research on Cancer (IARC) classified cell phone radiation as potentially carcinogenic to humans based on its review of hundreds of human and animal studies, including the the well-known 2010 INTERPHONE study. That study revealed that the heaviest cell phone users—those using a device for at least 30 minutes daily—experienced a 40 percent increased risk for gliomas, the most commonly diagnosed type of brain tumor. About 13,000 people from around the world were involved in the Interphone Study.
While much research on cell phone radiation effects has not been conclusive, experts generally agree that more research is needed. Especially given that newer research has found links between the devices and other adverse reactions, such as decreased sperm quality and motility and male fertility.

Using a cellular telephone while driving or walking clearly causes accidents, yet some people may be more worried about getting brain cancer from cell phones—a concern that has been largely dispelled by public health authorities.
The U.S. National Cancer Institute has concluded that “studies thus far have not shown a consistent link between cell phone use and cancers of the brain, nerves, or other tissues of the head or neck.” Similarly, the Food and Drug Administration has found “no increased health risk due to radiofrequency energy, a form of electromagnetic radiation that is emitted by cell phones.”
But fears of cell phone-caused brain cancer have persisted for at least two reasons, risk science expert George M. Gray said 7 September during a Capitol Hill briefing organized by AAAS with support from the Dana Foundation. First, public health messages have at times been mixed. The International Agency for Research on Cancer, part of the World Health Organization, recently classified radiofrequency electromagnetic fields as “possibly carcinogenic to humans.” That group pointed to human evidence showing an increased incidence of glioma, a malignant form of brain cancer, said Gray, a professor and director of the Center for Risk Science and Public Health at George Washington University.
At the same time, he said, people seem to be inherently fearful of unfamiliar, unseen or “man-made” risks, as well as risks beyond their control. Electromagnetic energy may thus trigger more dread than, say, a handgun. People using cell phones while driving may fear other drivers without fully recognizing that they have put themselves in harm’s way.
“People are much more concerned about radiation from nuclear power plants than they are about radiation from the sun,” Gray said. “More people die of sun-induced radiation in one year than have died in all of history from nuclear power plants.”
Scientific uncertainty obviously complicates risk communication, too. Radiofrequency energy, such as the waves emitted by cell phones, clearly does not cause damage to DNA in cells, which can in turn cause cancer. But different types of studies have offered conflicting results, said Nora Volkow, director of the National Institute on Drug Abuse at the National Institutes of Health. Some researchers have reported changes in people’s cognitive abilities before and after cell phone use, for example, while others have found no such effect. Studies based on cerebral blood flow as well as electroencephalography (EEG), a technology for measuring electrical brain signals, have been similarly inconsistent, she said.
“When we have a ‘risk,’ something that could cause harm, it automatically means we have uncertainty,” Gray noted. “If we knew exactly what happened, we would not talk about it as a ‘risk.’ It would be a ‘cause.’” In grappling with scientific uncertainty, he said, the public inevitably will want to understand both the cause of the risk and “how big a problem” they are facing.
Gray has investigated using numbers to communicate levels of risks since the public may at times be confused about terms such as “probably carcinogenic” versus “possibly carcinogenic to humans.” When the International Agency for Research on Cancer said that cell phones are “possibly carcinogenic,” that classification represented “the weakest result they could come to,” in the absence of evidence to clearly disprove a connection, Gray said.
But he added that risk assessment is highly subjective, varying significantly across cultures, and from person to person. It is well-known, for instance, that white males generally tend to worry about risks much less than women, or men or women of color.
In an effort to reconcile conflicting information, NIDA researchers recently analyzed increases in glucose metabolism within the brain following cell phone use (Journal of the American Medical Association, February 2011). Fluorescent glucose was injected into 47 research subjects who took part in the randomized study, and positron emission tomography was used to measure glucose activity after 50 minutes of exposure to cell phones that were either on or off, Volkow explained.
NIDA researchers found that when the phones were on, there was “a significant increase in brain glucose metabolism in the areas of the brain that were receiving the greatest exposure to electromagnetic radiation,” Volkow said. But she emphasized that scientists don’t know whether this increased activity is harmful in any way. Many activities, including speaking, can increase brain glucose metabolism.
Further research is needed. “If cell phones are carcinogenic, the effect is not going to be immediate, and it will require long-term exposure,” Volkow said, in conclusion. “If they do have carcinogenic effects, the effects are likely to be small.”
Meanwhile, she added, simple, common-sense steps may help to minimize or eliminate any possible risks associated with using cell phones: Take advantage of hands-free technology whenever possible, select phones with antennas located at the bottom rather than at the top of the device, send text messages rather than making calls when feasible, and limit the use of cell phones by children.
“I am very worried about cell phone use and accidents. Those are real injuries and real deaths and yet that’s not high on our national risk worry list,” Gray said. “There are real public health consequences to having a gap between the way we perceive risks and what the risks really are.”

Research efforts have been focused on the impacts of new technology on human health. One of the leading new factors is the technology of cell phones, which is predicted to have more than 1.3 billion worldwide users by the 2005. Cell phones have been of the fastest growing industries. Today most people have portable phones in their home, and/or cell phones. Theses devices are connecting people in convenient ways as their cost declines with the expand use.
Heath effects from phones and other communication devices is quickly becoming the focus of a great deal of research. It has been known that the subtle effect of light and colors with the human result in eyesight and that sound wave is energy transformed by the ear so we can hear.
Tests have been done by the Microwave institute of Zhejiang Medical University that show the effects of exposure to environmental electromagnetic fields (EMFs) EMFs are used in the cell phones we use today. Visual reaction time was prolonged and the scores of short-term memory tests were lowered in high intensity exposure groups. These test also showed that the energy fields could affect the central nervous system and immune system. Chronic exposure causes changes in some physiological parameters.
Pregnant woman have been warned to be careful and wary of using cell phones after research showed radiation produced by the devices caused defects in chicken embryos. Researchers still urge pregnant women to use cell phones until all risks are properly assessed. British mobile phone specialist Roger Coghill said the findings were ” enormously worrying”. Research has also been done on the possible effects of radio frequency radiation on prenatal development through the investigation in mice.
Australian research has found one the strongest links between cell phones and cancer. Mice were exposed to cell phone…

June 1 (Bloomberg) — Mobile phones may cause brain cancer in humans, a World Health Organization agency said, citing a review of studies.
Exposure to radiofrequency electromagnetic fields from handsets is greater than that from phone towers and base stations, Robert Baan, the senior scientist in charge of the International Agency for Research on Cancer report on the subject, said on a conference call with reporters. The fields are “possibly” carcinogenic, the same category as diesel fuel, chloroform and working as a firefighter, according to the IARC, based in Lyon, France, which classifies cancer risks.
This is the first time an agency working group has surveyed research on radiofrequency electromagnetic fields to make a definitive classification, the IARC said yesterday. The agency didn’t issue guidelines for cell-phone use and said more study is needed after finding some evidence for an increased risk of glioma, or brain cancer.
“It’s not at the moment clearly established that the use of mobile phones does in fact cause cancer,” said Kurt Straif, head of the IARC Monographs Program, adding that the research points to ways in which risks may be lowered. “For example, the highest exposure is from voice calls. If you use text messaging or headsets, this will lower the exposure.”
Concerns have risen in recent years that cell phones might be harmful to the health of people who use them, according to the WHO agency, which said there are 5 billion wireless subscriptions worldwide. The U.S. Federal Communication Commission has said devices with a specific absorption rate, the amount of radio-frequency energy absorbed by the body, within a set limit are safe.
The IARC considers studies in its reviews that may have flawed data, John Walls, vice president of public affairs for the CTIA wireless industry trade group in Washington, D.C., said in an e-mailed statement yesterday. The classification doesn’t mean mobile phones cause cancer, Walls said.
Nokia Oyj, the largest maker of mobile phones by the number of units sold, said today its products comply with international exposure guidelines and limits set by public health authorities. Apple Inc., the maker of the iPhone, didn’t respond to requests for comment yesterday.
“It is important to note that the IARC has not classified radiofrequency electromagnetic fields as definitely nor even probably carcinogenic to humans,” Espoo, Finland-based Nokia said in an e-mailed statement. The agency has “only concluded that, based on limited evidence, it may be possible that there could be some increased risk for certain cancers.”
The working group of 31 scientists from 14 countries met for seven days last month to study exposure to radiofrequency electromagnetic fields from mobile phones, radar, microwaves and radio, television and wireless signals. By classifying cancer risks, the IARC aims to provide scientific advice to government authorities.
The most recent research considered dated to 2004, and exposure levels from handsets have dropped over time, said Jonathan Samet, a University of Southern California professor and chairman of the working group.
The age of the studies also means the participants had used their phones for no more than 10 to 15 years, leaving open the question of the effect of longer-term exposure. The agency said the evidence was limited, and it may re-evaluate today’s recommendation once more recent research is available.
About a quarter of the more than 900 agents the agency has evaluated were determined to be “possibly carcinogenic.” The IARC lists substances as carcinogenic, probably carcinogenic, possibly carcinogenic, not classifiable and probably not carcinogenic. More than half the substances it has reviewed are listed as not classifiable.
The categorization that mobile phones are possibly carcinogenic to humans is appropriate, said Malcolm Sperrin, director of medical physics and clinical engineering at the Royal Berkshire Hospital in Reading, England.
“The justification for such a risk indicator respects the anecdotal evidence,” Sperrin said in comments distributed by the Science Media Centre in London. “The publication of more data along with a comprehensive justification of any conclusions is eagerly awaited, especially in relation to children.”

The cell phone industry is huge; there are currently more than 5 billion cell phone contracts worldwide, and the industry obviously has a lot to lose. According to Devra Davis, President of the Environmental Health Trust, the industry may fear that the negative health implications linked to frequent cell phone use will ultimately decrease the number of subscribers.
In her book titled Disconnect: The Truth About Cell Phone Radiation, What the Industry Has Done to Hide It, and How to Protect Your Family, she writes that “There’s a sense that, if you understand you need to be careful using a cell phone, some people might not use them at all.”
Interestingly, there are warnings on most cell phones, but they’re in extremely fine print, so hardly anyone reads them. Here’s one example:
“Use hands-free operation if it is available and keep the device at least 0.98 in. (25 mm) from your body (including the abdomen of pregnant women and the lower abdomen of teenagers) when the device is turned on and connected to the wireless network.”
Amazing! How many people were aware that cell phone should be kept about an inch away from the body at all times? Not many, I’ll bet.
If You Haven’t Yet, Minimize Your Exposure
Here are some tips for safe cell phone use:
• Use a headset or speaker phone whenever possible.
• Don’t sleep with the phone on your body or near it.
• If you must use a cell phone without a headset, make only essential calls and keep them as short as possible.
• Wait for the call to be connected before you place the phone near your ear.
• Limit your use of cell phones in enclosed metal spaces like elevators or vehicles. The metal enclosure can increase the risk in two ways: 1) The phone may need more power to establish a connection, and 2) the enclosure can trap the radiation and reflect it back to the user.
• Use an EMF (electromagnetic field) protection device. This can be as simple as attaching a ferrite bead to your headset wire. A ferrite bead or other EMF protection device can be cheaply and easily obtained at any electronics store.
• Don’t wear a bluetooth all the time; or if you do, don’t keep it turned on except when absolutely necessary.
• Finally, because cell phone use can decrease levels of certain nutrients, be sure to get adequate antioxidants, coQ10, and zinc. If you’re following the Save Our Bones Program, you’re already getting what you need.
Check Your Cell Phone’s Radiation Rating
This handy tool shows how much radiation is emitted by the most popular phones (but be aware that even a low radiation phone can be risky if used in less than optimal conditions). Use it to find out how much radiation your phone emits and if you’re in the market for a new phone, try getting one that has a low rating:

The Bottom Line
Since early history, we’ve been making tools to improve our quality of life. As technology advances by leaps and bounds, we should remain alert of its potential health consequences.
I believe that so long as we are aware of the possible problems, we can outsmart the risks and enjoy the convenience of new inventions.
Cell phones are the perfect example, so stay ‘connected’, informed, and enjoy the fruits of our inventive creativity.

While many people in the world focus their concern on the SARS problem, perhaps we should be looking at a problem that affects 137 million people in the U.S. and over 500 million worldwide. This problem is CPRS, Cell phone radiation syndrome. The radiation emitted from cellular phones that are used worldwide affect brain cells and can even cause cancer. It is a problem that can’t be seen immediately, a silent killer, that could have a he impact on over 500 million people in the world.
1. How do phones emit radiation?
In order to operate, cell phones have to emit signals via radio waves, which are comprised of RF energy, a form of electromagnetic radiation. When you talk on a cell phone a transmitter takes the sound of your voice and encodes it onto a sine wave. The radio waves that are used to send the encoded signal to the cellular tower are made up of electromagnetic energy. The transmitter is usually placed at the top of the cell phone. Since phones are placed right next to the head, which houses the brain, this radiation is emitted directly toward brain tissue.
2. Health Risks from CPS.
There is no doubt that cell phone radiation causes damage, the question is how sever is the damage, and what are the long term effects. There are two types of radiation:
A. Ionizing Radiation- The radiation contains enough electromagnetic energy to strip atoms and chemicals from tissue and alter chemical reactions in the body.
B. Non-ionizing Radiation- This type of radiation is typically safe. It causes some heating effect, but usually not enough to damage tissue.
Frankly there haven’t been enough studies on cell phone radiation to determine what type of radiation cell phones emit. Yet what little studies have been done point…

People use mobile phones of all time. It is one of these modern devices that most people think she would be able to survive without. In fact, if you go and questions is to what one thing that they can leave without the House, which most would say that their mobile phones. This is likely because apart from people for which enable communication with other people, mobile phones offer also dozens of purposes of Internet applications to work-related features and much more.
Although cell phones many uses, that make people’s lives easier, it is also important to remember that there are also some risks and dangers that everyone should be careful. Here are some of the risks associated with mobile phone usage.
Although there no statistical evidence yet, many studies link mobile phone use and brain tumors. Mobile phones emit radiofrequency energy or radio waves, which is a form of electromagnetic radiation. As some people know broadcast electromagnetic radiation such as that of the x-ray, can increase risk of cancer.
Many news talk report, how terrorists make to hide use of mobile phones and improvise explosive devices, which go by tech detectors, unrecognized as those found in airports.
Every year more than 50,000 people in the United States are injured after SMS while driving. For the same reason, about 6,000 people are killed. Using your phone while driving a major distraction is out as it gets your eyes from the road outside, off your hands steering wheel and your mind what is happening around you. The second you get distracted, are placing themselves at risk, which either could cause injury or death which.
The GPS tracking technology are now used by stalkers to the movement and the location of their objectives. It is very alarming news that 2010, the prices of the victims has increased in the year to 25,000 Americans, which are each year, according to the Ministry of Justice to the victims.
Also a person of eye health can affect mobile phones. When users on the mobile phone screen tend to long rigid, to forget to blink what keep moist in the eyes is important. When this happens, dry eyes can cause eye strain or even visually impaired lead, if you left untreated or unchecked.
Texter’s thumb, digital thumb and neck and arm nerve damage are just some of the physical health problems, who can suffer from mobile phone users.
Mobile phones are practical and useful devices, but they have some significant disadvantages mentioned above. These pieces of important information are not meant cause paranoia or frighten you, but you keep aware and informed about the dangers of the use of mobile phones. The good news is that you all smart so can avoid this with your phone. You should also include investments in mobile phone accessories that would allow hands-free, such as the headset with your phone. This cell phone accessories, along with other types as covers and cell phone leather cases, cell phone for a cheap price online are available.

Studies are currently being conducted of tumors of the brain and central nervous system and other site of the head and neck because the side of the head is where people place their cell phones when speaking. Cell phones are held next to the head when being used. At the moment though, studies have not shown any consistent link between cellular telephone use and cancer. Additional research is needed before firm confirmation can be made, (NCI).
A cellular telephone user is exposed to RF energy through the phoneâ??s antenna. The fact that the antenna of a hand-held cellular telephone is in the handset, it will most likely affect the brain and subsequently the nervous system because it is held against the head. So, the closer the antenna is to the head, the greater the danger of RF exposure. Therefore, a person will absorb less RF energy when the cellular unitâ??s antenna is at a significant distance away from the user, (NCI).
An important point is that the amount of RF energy increases the farther away the communication tower or base is from the cell phone and its user. In other words, the cell phone has to increase its RF energy output when the main tower is far away; thus, introducing a higher degree of radiofrequency radiation to the user. So, the closer the tower to the cellular phone, the less energy is generated by the phone, and therefore, the less radiation the cell phone user will be exposed to. This raises an important question. How can a person avoid dealing with cell phone towers that are too far apart?
One should not be a penny wise and a pound foolish. In general, the cheaper the cell phone plans and services of a new and less establish cell phone company are the lower the overall quality of the service is going to be, in regards to drop calls and such. This means that the towers are going to be farther apart. When the towers are farther apart, the amount of RF energy that will be required to maintain a connection will be tremendously high. All this high degree of radiation will be transmitted directly into the userâ??s body, especially if the wireless device is held close to the body, such as the head.
It cost cell phone companies millions of dollars to put up communication towers. So, if a company is going to always offer half price of the going rates of cell phone services, this company will not have the revenue to build many communication towers; thus, the towers that such companies will have will be dramatically less than that of companies with traditionally high levels of cellular telephone services and whom have been around for a long time.
A person will therefore be exposed to more RF radiation with phones from less well-known companies rather than phones with more well known companies because less well-known companies will not have the capital to build many towers as does the more establish and major companies. Yes, the company may be able to offer great cell phone plans and deals; however, the rate of radiation exposure will be much higher. One doesnâ??t need to be a rocket scientist to see the idea! Therefore, the more popular a less well-known cellular telephone company becomes, the more communication towers it will have and the higher its cellular phone plans will become!
There are more factors that determine how much RF energy a cellular telephone user experiences. Some of these are: number of calls; duration of calls; amount of cell phone traffic; the size of the cell phone unit itself; and the extended distance of the unitâ??s antenna, (NCI). In fact, many people speak on the cell phone for very long periods and this definitely is not a good practice. It is best to keep cell phone calls to a minimum. A cell phone should only be used sparingly.
How about the long term effect of cell phone use on children and teens? Researchers at the NCI conducted a study to see if children would be more at risk for brain cancers by using cell phones. Persons 18 years and older were used in the study. The study found that there were no possible risks among children who used cell phones. In fact, very few children used cell phone prior to the date of the study.
Therefore, there are no data concerning possible risk.
Nevertheless, there was concern that certain agents such as ionizing radiation and other chemicals pose great risks in children because they can affect the developing brain and nervous system. However, the study found that the radiation emitted by cell phones has not been demonstrated to cause brain cancers in humans of any age at this present time. More studies are still needed to fully rule out the possibility of cell phone induced cancers.
The bottom line is that cell phones should be used sparingly because no one knows for sure if they cause cancers in humans. A rule of thumb is to always use a head set or put the cell phone on speaker when speaking, and keep it away from the body at all times when it is turned on. It is always better to be safe than sorry!
