Our team of the clinical researchers in Lund, Sweden, found that electromagnetic radiation, such as those used in mobile communications, even at shallow power values, cause users' blood albumin to leak through the blood-brain barrier "BBB" into the brain tissue. The BBB is supposed to protect the brain against unwanted and toxic molecules potentially present in the blood, to transfer to the brain tissue. However, our team in Lund found that after exposure of rats to the radiation from mobile telephones, albumin in the blood leak into the brain and accumulates in neurons and glial cells.This matter would be of interest not only for researchers but also for radiation safety authorities and organizations worldwide as well as the general public.
