Medical/biological Study (experimental study)
The effect of weak 50 Hz magnetic fields on the number of free oxygen radicals in rat lymphocytes in vitro. med./biol. By: Zmyslony M, Rajkowska E, Mamrot P, Politanski P, Jajte J
Published in: Bioelectromagnetics 2004; 25 (8): 607 - 612 ( PubMed Entry , Journal web site )
Aim of study (according to author)
The aim of the study was verification of the hypothesis that weak power frequency magnetic fields affected the number of free oxygen radicals in living cells and that these alterations could be qualitatively explained by the radical pair mechanism. Iron ions (FeCl2) were used to stimulate the oxidation processes.
General category: magnetic field, 50/60 Hz (AC)

intact cell/cell culture (in vitro)
Methodsinvestigated material: intact cell/cell culture (in vitro)
time of investigation: after exposure
Main outcome of study (according to author)
Only in the lymphocytes exposed at 40 µT magnetic field directed along the Earth's static magnetic field there was a decrease of fluorescence in comparison to non-exposed samples. This observation seems to confirm the hypothesis that low level power frequency magnetic field affects oxidative processes which occur in living cells and that this effect can be explained by the radical pair mechanism.
