- Leif Salford and Bertil Persson were scientists who researched the impact of microwave radiation on the blood-brain barrier (BBB).
- The BBB is a membrane that separates the brain from the bloodstream and keeps potentially toxic substances out of the brain.
- Salford and Persson’s research began in the 1980s after Salford read a paper on changes in the BBB in rats undergoing routine MRI scans.
- They conducted experiments on rats that confirmed microwave radiation, even at low levels, can alter BBB permeability and cause chemicals to cross into the brain and kill neurons.
- Their research shifted in focus from a potential cancer treatment to a major health controversy as the use of cell phones, and wireless devices became more widespread in the 1990s.
- Their findings were published in peer-reviewed journals and presented at scientific workshops and conferences but were met with skepticism by some in the scientific community.
- Funding for their research dried up after a 2003 workshop led by a scientist with ties to industry, who rejected the idea of non-thermal effects on the BBB.

About the research that Leif Salford and Bertil Persson conducted on the blood-brain barrier (BBB) and microwave radiation and the controversy surrounding it?
Leif Salford and Bertil Persson are scientists who spent much of their careers researching the potential impact of microwave radiation on the blood-brain barrier (BBB). The BBB is a membrane that separates the brain from the bloodstream, keeping potentially toxic substances out of the brain. Salford, a neurosurgeon, became interested in this topic in the 1980s after reading a paper by a group at the University of Western Ontario that found that rats undergoing routine MRI scans showed changes in their BBB. Salford began to collaborate with Persson, a radiation physics professor, to investigate whether microwave radiation in MRI scans could open the BBB and deliver therapeutic drugs to treat brain tumors.
Over the next 20 years, Salford and Persson conducted several experiments on rats, confirming that microwave radiation, even at low levels, could alter BBB permeability. They also found that chemicals that had crossed into the brain due to this increased permeability could kill neurons. However, as the use of cell phones and other wireless devices became more widespread in the 1990s, the focus of their research shifted from potential cancer treatment to a major health controversy. The concern was that the microwave radiation emitted by these devices could be damaging brain cells, leading to neurological diseases such as Alzheimer’s.
Salford and Persson published their findings in peer-reviewed journals and presented them at scientific workshops and conferences. They were widely recognized as leaders in the field of microwave health research, and their work on the BBB was well-known among other researchers. However, in the late 2000s, interest in their research on the BBB faded, and funding for their work dried up.
The turning point in the controversy surrounding their research came in 2003 at a workshop held in Germany on the topic of BBB and microwave radiation. The workshop was led by a French scientist named Bernard Veyret, who was a strong supporter of the International Commission on Non-Ionizing Radiation Protection (ICNIRP). ICNIRP held the view that only the thermal effects of microwave radiation were harmful, and Veyret rejected the idea that there could be non-thermal effects on the BBB. Salford and Persson presented their findings at the workshop, but Veyret refused to acknowledge them. Another scientist, Dariusz Leszczynski, also presented findings that supported the work of Salford and Persson, but the workshop ultimately concluded with a call for more research to be conducted.
After the workshop, funding for Salford and Persson’s research dried up. At the same time, Veyret’s lab in Bordeaux received significant funding from various sources, including German and French telecommunications companies and trade groups. Veyret’s lab subsequently conducted research that contradicted the findings of Salford and Persson and concluded that there were no negative effects from microwave radiation other than those caused by overheating.
The controversy surrounding Salford and Persson’s research on BBB and microwave radiation highlights the importance of funding and politics in scientific research. The fact that their work was largely ignored and discredited after the 2003 workshop, while Veyret’s lab received significant funding to conduct research that contradicted their findings, raises questions about the influence of industry funding and conflicts of interest on scientific research. It also highlights the importance of considering all potential impacts, including non-thermal effects, when studying the health effects of microwave radiation.
In conclusion, the research conducted by Leif Salford and Bertil Persson on the BBB and microwave radiation bring attention to the potential health risks associated with prolonged exposure to wireless devices. The fact that their work was met with skepticism and ultimately dismissed, while research conducted by those with industry ties reached conflicting conclusions, highlights the need for independent, unbiased research to be conducted in order to understand the potential health risks associated with microwave radiation fully. Scientists need to be able to conduct research free from conflicts of interest and for funding to be made available for research on all potential impacts, not just those that are currently accepted or popularly believed. It is also important for the scientific community to consider all potential explanations for observed phenomena rather than dismissing findings that do not align with current beliefs or paradigms. The research conducted by Salford and Persson may have been dismissed. Still, it serves as a reminder of the importance of considering all potential risks and the need for unbiased research in order to protect public health.
