Mobile Phones Radiofrequency Does not Induce Headaches /BP /or Other Health Risk

The continuing world-wide concerns over EMF, particularly those associated with the rapidly-growing mobile telephone communication systems and from the use of AC electric power.Its goal of uniform international standards for exposure to EMF which identifies knowledge needed for a better assessment of any possible health risks.There is also growing public concern about cell phones and base stations.

The risk of being in a car accident while talking on a cell phone is higher than any risk for cancer.The most common adverse effects of mobile phone use while driving were taking eyes off the road, slowing down, lack of concentration, failing to indicate, lane drift and sudden braking.

A study by scientists at the University of Lund, near Malmo, exposed rats to microwave pulses similar to the emissions from a mobile phone to calculate the effect on the body's blood-brain barrier, the Daily Mail reports. Within two minutes of exposure, the rats' brain tissue was found to be opened up to proteins and toxins contained in the blood after the defence mechanism was disabled.However they concluded "we are not sure yet whether this is a harmful effect, but it seems that molecules such as proteins and toxins can pass out of the blood while the phone is switched on and cross into the brain".

Recently a team of researchers from the Institute of Cancer Research and the universities of Leeds, Nottingham and Manchester found no link between phone use and the growth of glioma, the most common type of brain tumour.But the researchers admitted that where tumours did occur they were on the side of the head most used to make calls.

"This finding may be due to people with glioma brain tumours linking mobile phone use to the side of the tumour and therefore over reporting the use of a phone on the same side as their tumour," said Patricia McKinney, professor of paediatric epidemiology at Leeds Institute of Genetics, Health and Therapeutics. "This results in under reporting use on the opposite side of the head."

Public concern over the siting of cell phone base stations has risen in the past year, and concerns regarding cancer risks (LF EMF) and EM hypersensitivity continue. The national radiation protection agency of Sweden has published a leaflet on cell phone base stations, which concluded that such stations pose no health risks to the general population.The Swedish National Institute for Working Life (NIWL) unit in Umea reported results from a cross-sectional, survey-based epidemiology study of
subjective symptoms in users of cellular phones. The study found that ISM (analog system) users do not report more of such symptoms than do GSM (digital) phone users; if anything, the data support the opposite finding. Post hoc analysis revealed an association of some such symptoms (headache, fatigue, warmth sensations) with the amount of phone use.

Research also being carried out under the aegis of the Ministry of Environment, including epidemiology of 50 Hz EMF and child leukemia, the effect of GSM phones on human hearing, human stimulation thresholds in MRI fields, and human and animal dosimetry.

so they suggested it's safe to talk on a cell phone, but avoid placing your cell phone within six inches of your ICD implantation site when the phone is turned on. Although unlikely, your ICD could misinterpret a cell phone's signal as a heartbeat and withhold pacing, producing symptoms such as sudden fatigue.

Cell phones use low levels of radiofrequency energy (RF). Exposures to low levels of RF from cell phones have not been found to cause health problems.The U.S. Food and Drug Administration (FDA) and the Federal Communications Commission (FCC) have developed guidelines that limit the amount of radiofrequency energy that cell phones are allowed to give off.

New reports continue to be published several times a year, suggesting that there might be health risks from mobile phones electromagnetic radiation. Yet other studies show little or no health impact.There can be no doubt any longer that mobile phone radiation affects living cells. For example research shows that nematode worms exposed to mobile phone radiation produce more eggs, release stress hormones and grow larger.

The RF exposure from cell phones is measured in Specific Absorption Rate (SAR). The SAR measures the amount of energy absorbed by the body. The SAR permitted in the United States is 1.6 watts per kilogram (1.6W/kg).According to the FCC, this amount is much lower than the level shown to cause any changes in laboratory animals. Every cell phone manufacturer is required to report the RF exposure of each of its phone models to the FCC.

Exposure to the radiofrequency fields generated by mobile phones does not cause head pain or increase blood pressure, according to a Norwegian study. Instead, people who experience such symptoms do so because they expect that they will occur, the findings suggest earlier.

Dr. Gunnhild Oftedal and associates at the Norway University of Science and Technology in Trondheim recruited 17 subjects who "regularly experienced pain or discomfort in the head during or shortly after mobile phone calls lasting between 15 and 30 minutes."

The participants were tested during mobile phone radiofrequency exposure and sham exposure, without knowing which session was which. Each session lasted 30 minutes, and 65 pairs of trials were conducted.

As reported in the medical journal Cephalalgia, the subjects said they felt an increase in pain or discomfort during 68 percent of all trials. The degree of symptoms was not associated with the order of trials.

The researchers observed no statistically significant correlations between actual exposures and the subjects' reports of symptom severity, and no effects of exposure on changes in heart rate or blood pressure.

Oftedal's team concludes that the most likely explanation for the headaches and discomfort reported by the subjects "is that the symptoms are due to negative expectations."

The World Health Organization has concluded that serious health effects (e.g. cancer) are very unlikely to be caused by cellular phones or their base stations, and expects to make recommendations about mobile phones in 2007–08.

However, some National Radiation Protection Authorities, i.e. Austria Germany and Sweden, recommend their citizens to minimize radiation. Examples of recommendations are:
