Overview On Cell Phone Radiation & Ftc Waveshield
Cell phones produce electromagnetic radiation. Cell phones discharge certain signals known as radio frequency energy, a form of electromagnetic radiation. There is lot of news these days as to whether cell phones emit radiation which affects our health. Cell phones are placed close to our head which results in direct radiation to the head. Ionizing and Non-Ionizing radiation are the two types of electro magnetic radiation. Radiation can damage human tissue if exposed to high levels of radio frequency radiation. Some of the health problems that can arise due to cell phone radiation are Cancer, Brain tumors, Alzheimer, Fatigue and Headache. According to a survey, higher levels of cell phone radiation can heat biological tissue and cause damage such as burns.
In U.S. every cell phone model is tested and meets FCC standards before it is sold in the market. SAR (specific absorption rate) is a way of measuring the quantity of radio frequency energy that is absorbed by the body. A cell phone or cordless phone should have less than 1.6 watts per kilogram SAR level.
Some of the highest radiation cell phones in United States are as follows: Motorola V195s has 1.6 SAR level. Motorola ZN5, VU204, W385, i335 have 1.59, 1.55, 1.54 and 1.53 SAR levels. Some of the lowest radiation cell phones in United States are as follows: Samsung Eternity SGH-A867, SGH-G800, Soul, Innov8, SHG-T229, and SGH-i450 have 0.194, 0.23, 0.24, 0.287, 0.383 and 0.457 have SAR levels.
Some of the cell phone radiation protection tips are as follows: When you are speaking over the phone, try to keep the phones as far as possible from the ear. For long conversation use landline corded phones. Do not use cell phones in areas where the signal is week. As far as possible, text messages instead of making a call. Buy a cell phone that has lower SAR. Do not allow children to use a cell phone except for emergencies. Children are more sensitive to radiation because their bodies are developing. Don’t keep the cell phone near your body at night. Do not put the cell phone in your pocket while in use. Nowadays various cell phone protection devices are available in the market which can protect you from radiation.
Many people are facing health problems due to cell phones. Many people are prone to high blood pressure due to cell phones. A study has found out that if people use cell phones for long hours they can face problems like burning skin, headaches and fatigue, sleeping disorders and brain tumors. You can also face short term memory loss problems. Some researches claim that holding a cell phone on the ear for long hours can damage muscles, bones, tendons and discs.

Cancer Center in Pittsburgh Warns of Cell Phone Risks
The head of a prominent cancer research institute issued an unprecedented warning to his faculty and staff Wednesday: Limit cell phone use because of the possible risk of cancer.
The warning from Dr. Ronald B. Herberman, director of the University of Pittsburgh Cancer Institute, is contrary to numerous studies that don't find a link between cancer and cell phone use, and a public lack of worry by the U.S. Food and Drug Administration.
Herberman is basing his alarm on early unpublished data. He says it takes too long to get answers from science and he believes people should take action now especially when it comes to children.
"Really at the heart of my concern is that we shouldn't wait for a definitive study to come out, but err on the side of being safe rather than sorry later," Herberman said.
No other major academic cancer research institutions have sounded such an alarm about cell phone use. But Herberman's advice is sure to raise concern among many cell phone users and especially parents.
In the memo he sent to about 3,000 faculty and staff Wednesday, he says children should use cell phones only for emergencies because their brains are still developing.
Adults should keep the phone away from the head and use the speakerphone or a wireless headset, he says. He even warns against using cell phones in public places like a bus because it exposes others to the phone's electromagnetic fields.
The issue that concerns some scientists though nowhere near a consensus is electromagnetic radiation, especially its possible effects on children. It is not a major topic in conferences of brain specialists.
A 2008 University of Utah analysis looked at nine studies including some Herberman cites with thousands of brain tumor patients and concludes "we found no overall increased risk of brain tumors among cellular phone users. The potential elevated risk of brain tumors after long-term cellular phone use awaits confirmation by future studies."
Studies last year in France and Norway concluded the same thing.
"If there is a risk from these products and at this point we do not know that there is it is probably very small," the Food and Drug Administration says on an agency Web site.
Still, Herberman cites a "growing body of literature linking long-term cell phone use to possible adverse health effects including cancer."
"Although the evidence is still controversial, I am convinced that there are sufficient data to warrant issuing an advisory to share some precautionary advice on cell phone use," he wrote in his memo.
A driving force behind the memo was Devra Lee Davis, the director of the university's center for environmental oncology.
"The question is do you want to play Russian roulette with your brain," she said in an interview from her cell phone while using the hands-free speaker phone as recommended. "I don't know that cell phones are dangerous. But I don't know that they are safe."
Of concern are the still unknown effects of more than a decade of cell phone use, with some studies raising alarms, said Davis, a former health adviser in the Clinton Administration.
She said 20 different groups have endorsed the advice the Pittsburgh cancer institute gave, and authorities in England, France and India have cautioned children's use of cell phones.
Herberman and Davis point to a massive ongoing research project known as Interphone, involving scientists in 13 nations, mostly in Europe. Results already published in peer-reviewed journals from this project aren't so alarming, but Herberman is citing work not yet published.
The published research focuses on more than 5,000 cases of brain tumors. The National Research Council in the U.S., which isn't participating in the Interphone project, reported in January that the brain tumor research had "selection bias." That means it relied on people with cancer to remember how often they used cell phones. It is not considered the most accurate research approach.
The largest published study, which appeared in the Journal of the National Cancer Institute in 2006, tracked 420,000 Danish cell phone users, including thousands that had used the phones for more than 10 years. It found no increased risk of cancer among those using cell phones.
A French study based on Interphone research and published in 2007 concluded that regular cell phone users had "no significant increased risk" for three major types of nervous system tumors. It did note, however, that there was "the possibility of an increased risk among the heaviest users" for one type of brain tumor, but that needs to be verified in future research.
Earlier research also has found no connection.
Joshua E. Muscat of Penn State University, who has studied cancer and cell phones in other research projects partly funded by the cell phone industry, said there are at least a dozen studies that have found no cancer-cell phone link. He said a Swedish study cited by Herberman as support for his warning was biased and flawed.
"We certainly don't know of any mechanism by which radiofrequency exposure would cause a cancerous effect in cells. We just don't know this might possibly occur," Muscat said.
Cell phones emit radiofrequency energy, a type of radiation that is a form of electromagnetic radiation, according to the National Cancer Institute. Though studies are being done to see if there is a link between it and tumors of the brain and central nervous system, there is no definitive link between the two, the institute says on its Web site.
"By all means, if a person feels compelled that they should take precautions in reducing the amount of electromagnetic radio waves through their bodies, by all means they should do so," said Dan Catena, a spokesman for the American Cancer Society. "But at the same time, we have to remember there's no conclusive evidence that links cell phones to cancer, whether it's brain tumors or other forms of cancer."
Joe Farren, a spokesman for the CTIA-The Wireless Association, a trade group for the wireless industry, said the group believes there is a risk of misinforming the public if science isn't used as the ultimate guide on the issue.
"When you look at the overwhelming majority of studies that have been peer reviewed and published in scientific journals around the world, you'll find no relationship between wireless usage and adverse health affects," Farren said.
Frank Barnes, who chaired the January report from the National Research Council, said Wednesday that "the jury is out" on how hazardous long-term cell phone use might be.
Speaking from his cell phone, the professor of electrical and computer engineering at the University of Colorado at Boulder said he takes no special precautions in his own phone use. And he offered no specific advice to people worried about the matter.
It's up to each individual to decide what if anything to do. If people use a cell phone instead of having a land line, "that may very well be reasonable for them," he said.
Susan Juffe, a 58-year-old Pittsburgh special education teacher, heard about Herberman's cell phone advice on the radio earlier in the day.
"Now, I'm worried. It's scary," she said.
She says she'll think twice about allowing her 10-year-old daughter Jayne to use the cell phone.
"I don't want to get it (brain cancer) and I certainly don't want you to get it," she explained to her daughter.
Sara Loughran, a 24-year-old doctoral student at the University of Pittsburgh, sat in a bus stop Wednesday chatting on her cell phone with her mother. She also had heard the news earlier in the day, but was not as concerned.
"I think if they gave me specific numbers and specific information and it was scary enough, I would be concerned," Loughran said, planning to call her mother again in a matter of minutes. "Without specific numbers, it's too vague to get me worked up."
