A major study carried out by scientists in Finland suggests that radiation from mobile phones causes changes to the brain. Professor Darius Leszcynski headed up the two-year program at Finland’s Radiation and Nuclear Safety Authority. The researchers discovered that radiation from cellular phones can cause activity in hundreds of proteins in human cells grown in a laboratory. It is the first time that scientists have looked at the effects of mobile phone radiation on human cells rather than those of rats.
The scientists found that changes in cells that line blood vessels could weaken the functioning of the brain’s protective shield against harmful substances. These changes damaged the blood-brain barrier—a safety barrier that stops harmful substances in the blood from entering the brain. The study found that exposure caused increased activity in a protein called hsp27 linked to the functioning of the blood-brain barrier. “[Increased protein activity] might cause cells to shrink—not the blood vessels but the cells themselves—and then tiny gaps come between those cells through which some molecules could pass,” said Professor Leszcynski. Speaking to BBC News Online, he stated: “The blood-brain barrier has been shown to be affected by radiation in animal studies. There is a lot of uncertainty about whether this happens in humans. We have shown some biological effects. If it did happen it could lead to disturbances, such as headaches, feeling tired or problems with sleeping. A study by a Swedish research group even suggested it could lead to Alzheimer’s disease.” He also stated that a study by French scientists found similar results in rats.
An abstract of the Finnish study was published in the May 2002 issue of Differentiation. The authors concluded: “Based on the known functions of hsp27, we put forward the hypothesis that mobile phone radiation-induced activation of hsp27 may (1) facilitate the development of brain cancer by inhibiting the cytochrome c/caspase-3 apoptotic pathway and (2) cause an increase in blood-brain barrier permeability through stabilization of endothelial cell stress fibers. We postulate that these events, when occurring repeatedly over a long period of time, might become a health hazard because of the possible accumulation of brain tissue damage. Furthermore, our hypothesis suggests that other brain damaging factors may co-participate in mobile phone radiation-induced effects.”
An article published by Earthpulse Press, entitled Cell Phone Convenience or 21st Century Plague by Dr. Nick Begich and James Roderick, postulates that cell phones “have been one of the fastest growing industries in modern history,” with cell phone usage estimated to climb to 1.3 billion users by the year 2005.
The article is a compilation of much of the research and reporting produced over the last 10 years in the cell phone area.
Among the article’s many citations is the demand by British scientists that mobile phones carry a health warning. “Amid an explosive growth of mobile communications, concerns are mounting about cellular telephones potential links to health problems ranging from headaches to brain tumors. … Mobile telephones are arguably the most radiative appliance we have ever invented apart from the microwave oven and people are putting them by their heads—arguably the most sensitive part of the body,” said bioelectromagnetics scientist Roger Coghill, as reported by Reuters in January 1998. “Cell phones emanate microwave radiation, and human brains may absorb up to 60 percent of that energy.”
The Begich/Roderick article continues: “Researchers have shown that low intensity microwave exposure opens up the blood/brain barrier, a biological effect which can allow the release of dangerous chemicals into the brain.” The article goes on to quote from the September 15, 1999 issue of Svenska Dagbladet: “New Swedish research shows that the radiation from mobile phones might make it easier for poison to penetrate the brain. The findings could explain the diseases that American soldiers who have participated in high-tech warfare are suffering from. The unexplained symptoms of American soldiers of the Kuwait war are suspected to link to the medication they took against nerve gas. The microwaves surrounding soldiers in high-tech warfare could have opened the blood-brain barrier, and the medication penetrated into the brain. The possibility is now being investigated by the US Air Force in co-operation with the Lund [Swedish] scientists.”
