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.”
