A Tale of the Blood-Brain Barrier and Mobile CommunicationDedicated to Leif G, Salford on his 80th birth day 2021-12-07

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.

Environmental Radiological Health: My scientific career began 1963 with investigations of the health impact of the radioactive fall-out from atmospheric nuclear weapons tests in the food-chain lichen-reindeer-man. Since 1972 I have been deeply engaged in gamma-spectrometry field studies around nuclear power plants in Sweden, and have studied the impact of various meteorological parameters on the recorded radiation field spectra. In 1980, 1989-90, 1994 and 1996 I participated in the Swedish Polar Expeditions to Arctic (North Pole September 10, 1996) and Antarctica (1989-90) with programs in marine radioecology and radio meteorology. 2011-present active in 210Po toxicity and radioecology.

Biomedical effects and Health impact of Electromagnetic Fields: Biomedical applications of NMR also involve the potential health hazards of clinical NMR-examinations and I have written extensive monographs on this subject. I also studied exposure to electromagnetic fields corresponding to those used in GSM mobile communications and found increased permeability of the blood brain barrier in the rat (BBB) to endogenous albumin. The interaction of static and extremely low frequency magnetic fields with calcium ion transport has been studied in normal and transformed human lymphocytes and in rat thymic cells human lymphocytes as well as Ca-45 transport in membrane vesicles of plant cells. Recent studies together with Belyaev et al at Stockholm University indicate that GSM microwaves do not induce DNA breaks or change chromatin, but affect expression of genes in rat brain under specific conditions of exposure. At present I am studying the use of pulsed electric fields for tumour and gene therapy and bio-impedance spectroscopy for dosimetry and tissue characterization.
