Pulsed RF: Plausible Cause of Havana Syndrome

A newly declassified, though heavily redacted, report from the intelligence community has put renewed emphasis on the possibility that the condition known as “Havana Syndrome” could be caused by pulsed RF energy.

“Electromagnetic energy, particularly pulsed signals in the radiofrequency range, plausibly explains the core characteristics [of Havana Syndrome, also called ‘anomalous health incidents’] although information gaps exist,” the intelligence panel concluded.

Abandoning Inconvenient Science

Leif Salford celebrated his 80^th birthday on December 7. An emeritus professor at Sweden’s Lund University and a noted neurosurgeon, Salford spent much of his career treating patients with brain tumors. Over the years, he became frustrated as, all too often, he was unable to save them with a scalpel.

In 1987, Salford came across a paper in Neuroscience Letters from a group at the University of Western Ontario, who had found that rats undergoing the equivalent of a routine MRI scan showed changes in their blood-brain barrier. The BBB is a membrane that keeps potentially toxic substances in the bloodstream from getting into the brain. It’s not a perfect barrier —it can leak. The Canadians reported that something about the electromagnetic exposures during the MRI scan had increased the permeability of the rats’ BBB. It had become more porous.

If microwaves used in the MRI were responsible, Salford thought....

“We report a rhythm of BBB permeability driven by a clock within the BBB.”

Might this prompt a new look at RF and leakage through the blood-brain barrier —an unresolved controversy that has been festering for more than 40 years? Based on a new study published in Neuron. See also the accompanying editorial.

“Exposure to 900 MHz EMFs Activates the MKP-1/ERK Pathway and Causes Blood-Brain Barrier Damage and Cognitive Impairment in Rats,” Brain Research, posted online January 15, 2015.

“[T]his is the first study to demonstarte that 900 MHz EMF affected spatial memory in rats exposed to EMF for 28 days but not in rats exposed to EMFs for 14 days.” … Also “provides evidence that 900 MHz [EMFs] resulted in the disruption of BBB permeability…” From China’s 3rd Military Medical University in Chongqing.

Industry Rules RF

If you had any doubts that the wireless industry is in total control of the RF health debate, you need only to have gone to the workshop held at the FCC’s Washington headquarters on June 28. By the end of the day, the fog would have lifted.

Motorola’s Joe Elder told the assembled delegates from the U.S., the EU, Japan and Korea that the health issue is just about settled. There is no credible evidence that casts doubt on the current 4 W/Kg threshold for ill effects from mobile phone radiation, he said.
