Cell Phone Radiation – Top 10 Least Radiation-Emitting Cell Phones of 2009

All cell phones, once powered on, emit certain amounts of electromagnetic radiation in the microwave radio frequency range. During the past 15 years or so, when mobile phone use has become phenomenally prevalent worldwide, the effects of this radiation on human health has come under intense study and has been the subject of numerous heated debates. These past years, we’ve seen report after report that associated prolonged mobile phone use and exposure to differing amounts of cellular phone radiation to brain tumors, cancer, stress, headaches, cognitive problems, and sleep disorders.

Most of these studies, however, have either been disputed by other scientists or deemed as biased by other groups who also produced evidence to the contrary. As such, there’s no definitive, undisputed conclusion, as of yet, about cell phone dangers. Scientists warn, correctly, that there’s so much that we don’t know about the effects of mobile phone radiation, and that the full impact may actually be known years from now when it is too late to reverse any damage.

“The latency between exposure and brain cancer could be 20 or 30 years,” observes Professor Devra Davis, at the University of Pittsburgh Cancer Institute. By using cellular devices without any clear understanding of the dangers, “we are basically treating ourselves like lab rats in an experiment without any controls”

To mitigate potential cell phone dangers, experts recommend certain safe practices in using wireless devices. Some of the most common recommendations are: Keep your cellular phone away from your body, text more and talk less, use headset or speakerphone function, use your land line, turn off your mobile phone while charging, keep cell phones away from children, and purchase or use phones that have been certified or tested to emit the least amount of radiation.

It is with the intention of educating the public about the dangers of mobile phone radiation that the Environmental Working Group (EWG) has conducted an exhaustive study, covering over a thousand cell phone models in the market, detailing the amount of radiation that each mobile phone emits. The EWG is a 501(c)(3) non-profit organization, founded in 1993 by Ken Cook and Richard Wiles, that aims to “use the power of public information to protect public health and the environment.”

Here are the 10 least radiation-emitting cell phones, according to the EWG report:

1. Samsung Impression (SGH-a877) [AT&T]

2. Motorola RAZR V8 [CellularONE]

3. Samsung SGH-t229 [T-Mobile]

4. Samsung Rugby (SGH-a837) [AT&T]

5. Samsung Propel Pro (SGH-i627) [AT&T]

6. Samsung Gravity (SGH-t459) [CellularONE, T-Mobile]

7. T-Mobile Sidekick [T-Mobile]

8. LG Xenon (GR500) [AT&T]

9. Motorola Karma QA1 [AT&T]

As pointed out by the CTIA, the wireless industry’s lobbying group, there is yet no conclusive and fully substantiated study about cell phone dangers. However, it is no secret that government agencies in some countries have started to post warnings and direct cell phone manufacturers to clearly indicate the amount of radiation that each model they sell to the public actually emits.

Until we’re finally able to bridge that gap in our knowledge on the dangers of cell phone radiation, we can only take precautionary measures to protect ourselves. One important way to protect our health, is by buying or purchasing mobile phone models that have the least amount of radiation.

The Cancer-Cell Phone Connection – Why We Must Take It Seriously

Over the past few years several study groups have reported that cell phone radiation is not dangerous and that we don’t need to worry about it. In particular, we don’t need to worry about it causing cancer. Some of them, in fact, have reported that the debate is over, and that cell phones are completely safe. As a result, most of the research on the topic has virtually ceased in the US. At the same time, however, research has continued in other countries, and it has increasingly shown that we cannot ignore the dangers. First of all, as any scientist working on cancer will tell you, it’s almost impossible to prove beyond a doubt that something (in this case, cell phone radiation) does not cause cancer. One of the problems is that cancer takes 20 years or more to develop after it has been initiated. None of the studies that have been made have taken this into consideration; most are tests on animals, or statistical surveys. In many ways the present situation is similar to that for smoking in the 1950’s and 60’s. Everyone was sure it had little effect on our health, and there was no evidence that it caused cancer. But as the years went by, the evidence came, and soon there was no doubt.

The cancer-cell phone connection is particularly worrisome in light of the increase in brain tumor rates in the US over the past few years. They have increased by over 25 percent since 1975; by 2001, in fact, 185,000 Americans had some form of brain cancer, and it is estimated that this will increase to 500,000 by 2010 and to one-million by 2015. How many of these cases are due to cell phones? We do not know.

The radiation from cell phones is in the form of microwaves, the same waves that are used in microwaves ovens (and they’re also very close in frequency to radar waves). They are, of course, over a thousand times weaker that microwave-oven radiation, but microwaves are not used for cooking because they are extremely energetic (they are not); they are used because they penetrate tissue easily.

The three main health hazards to our bodies are the dangers to:

Our DNA

The functioning of our cells

The neurons and so on in our brain

Our “code of life” — in other words, the instructions for everything that goes on in our body — is contained in the sequence of base units in DNA. If any of these units are suddenly changed, or “mutated,” our genetic code is changed. And one of the major things that causes mutations is radiation. Microwaves cannot break the stronger bonds (such as valence bonds) in DNA, but the genetic code is held in place by relatively weak hydrogen bonds, which can easily be broken.

Furthermore, the dangers do not end with the DNA inside the cells. On the cell surface are “receptors” that allow some molecules to pass into the interior of the cell, and stop others, from entering. They play a very important role in the health of the cell in that they allow nutrients through, but stop such things as toxins, bacteria, and viruses. These receptors also play another important role: they control cell division and growth. Normally, cell division continues until something tells it to stop. One of the things that stops it is when a cell comes in contact with another cell (perhaps of a different type); receptors sense this cell and send a signal for the growth to stop. If the receptors become damaged, this signal will not be sent, and the growth may continue indefinitely, and may eventually lead to cancer.

Experiments have shown that microwaves can trigger these receptors, causing various types of biochemical reactions that make the cell membrane less permeable, We are still not sure what the overall effects are in such cases, but the fact that microwaves radiation (of the same intensity as in cell phones) can alter our cells is not good news.

With this it might seem that cells and the DNA within them are the weak spots for microwave radiation, but there is another equally worrisome area of the body. Cell phone users hold their phones to their ears, with the antenna only a few inches from their brain, and our brain is controlled (to some degree) by waves similar to microwaves. Most of the signals in the brain are electrochemical in nature, consisting partly of electrical currents and partly of chemical reactions. But there are also “brain waves’ within the brain. When you are awake your brain emits what are called beta waves of frequency 8 to 25 vibrations/second (also called Hertz). This is much lower than the frequency of the microwaves in a microwave oven, which are 850 MHz (million Hertz) to 1900 Mhz. But all cell phones also use low, pulsed frequencies, referred to as TDMA and DTX; they have frequencies of 8.34 HZ and 2 Hz respectively. And it is possible that they can interact with brain waves. Furthermore, when such reactions occur, both waves are changed.

Studies have also recently shown that the blood-brain barrier, which is a barrier within the brain that stops various chemicals and other harmful substances from entering the brain, is also affected by microwaves. Studies in Sweden, for example, have shown that when capillaries such as those in the brain are are radiated with microwaves, they allow certain chemicals through that normally don’t get through. Other studies have verified the result.

It’s easy to see from all this that the risk of cell phone radiation to adults is something we shouldn’t just shrug off, but as it turns out, the risk to children is much higher. One of the reasons is that their skulls are thinner, and radiation penetrates it much easier. In addition, the absorption of radiation is higher in a child’s skull because of a phenomenon called “resonance.” And finally, the nervous and immune systems of children are still forming and they are therefore more susceptible to the effects of radiation.

What can you do to minimize the danger? If you use a cell phone, keep the antenna as far from your head as possible, and limit your time on the device. Use conventional phones for very long conversations. Finally, do not use cell phones in a car; because of the shielding, the power has to be significantly increased for it to work.

Is My Cell Phone Slowly Damaging My Brain?

The first time I wondered whether mobile phones affect the cells of the brain was when I had placed my cell phone near the computer monitor. The computer system I use has the old-modeled CRT monitor. I had just placed the phone near the monitor, and after some time I saw a lot of disturbance on the screen. Thinking that I had received a text or a call, I checked my mobile phone; there was nothing. That’s when I wondered if the phone was emitting some kind of electronic wave all the time, even when it was not being used. I generally keep the mobile phone near my head when I fall asleep. So, are those waves or impulses, whatever that are being emitted from the phone affecting my brain?

Worried, I decided to do some research. I found that there has been a lot of research done in the recent past, especially after cell phones became so very popular. One study showed that the radiations from the cell phone considerably increased brain cell activity. There are other research studies that show that the electromagnetic radiation emitted by the phones could even be carcinogenic.

Way back in 2011, the International Agency for Research on Cancer (IARC) grouped radiations from the cell phone under Group 2B. According to their lingo, this classification means that the radiations could be possibly carcinogenic. Only further research will show the entire truth.

One group of researchers conducted a study with 47 healthy adults. Some of them were asked to hold the phone near their ear while others were asked to do the same, but with the phone switched off. The researchers found considerable brain activity in those who held the phones that were switched on.

It is yet to be scientifically documented if these waves cause any significant damage to the brain cells. But if we look at the way the few studies are going, it could mean that the omnipresent cell phone could soon become the bane of our life. Another frightening aspect we should think about is how these radiations could affect children’s brains. Not only are their skulls thinner than that of the adults, but the brains are not yet fully developed. So, could this mean that cell phone radiations are even more dangerous for them?

The cell phone has become an integral part of life, and there is no way we can totally cut it off from our lives. The only thing that I could think of is not to talk on the phone for long. If I have to do it, I would rather use headphones. And these days I don’t keep the cell phone near my head when I sleep. Stay away harmful radiations…
