Since Allan Frey, whose work is also highlighted here, discovered in 1975 that microwave radiation causes the blood-brain barrier to leak, at least a dozen laboratories throughout the world have corroborated this effect. Currently the most active research of this kind is being done at Lund University in Sweden.
Dr. Leif Salford is a neurosurgeon at Lund University Hospital, and Chairman of the Department of Neurosurgery. Since 1988 he has led a team of researchers that have exposed thousands of laboratory rats to microwave radiation from various sources. Since the late 1990s they have used mobile telephones as the source of this radiation.
Their results have been consistent and alarming: not only does radiation from a cell phone damage the blood-brain barrier, but it does so at even when the exposure level is reduced a thousandfold. Even more disturbingly, and contrary to what was expected, the damage to the blood-brain barrier worsened when the experimenters reduced the exposure level. The implies that SAR ratings for cell phones may be worthless and that it may not be possible to make cell phones safer by reducing their power.
In laboratory rats, Salford’s team has demonstrated that blood-brain barrier leakage occurs after only two minutes of exposure. Further, a single two-hour exposure to a cell phone, even at reduced power, was shown to damage or destroy up to two percent of an animal’s brain cells.
In other experiments in Salford’s laboratory, long term exposure of rats to a cell phone caused memory impairment, and a single six-hour exposure at extremely low power levels caused genetic damage. Exposure to a low-frequency magnetic field (low frequencies are also emitted by cell phones) caused disturbances of calcium transport in cells.
Salford has called the use of cell phones by human beings “the largest biological experiment ever,” and he calls the potential implications of his laboratory results “terrifying.” “Those who might normally have got Alzheimer’s dementia in old age could get it much earlier,” he said. “Perhaps putting a mobile phone repeatedly to your head is something that might not be good in the long term.”
