Papežová, S. - Papež, V.: An evaluation of the influence of a magnetic field on a human subject with the use of bio-impedance. Journal of Physics: Conference Series. 2010, vol. 2010, no. 200, p. 122007/1-122007/4. ISSN 1742-6588
The influence of a magnetic field on a living human organism was monitored using a
bio-impedance evaluation of vasodilatation effects. A quantitative evaluation of the influence
of a magnetic field on a human being was implemented by means of a quantitative evaluation
of changes in the bio-impedance of the tissue. The pulse of the magnetic field was controlled
by a pseudo-random impulse signal using a power switch that controlled the current of the
applicator coil. The peak magnetic field flux density was approximately 60 mT. The bioimpedance
was measured by a four-electrode method by means of a radiofrequency narrow
band vector bioimpedance meter. Experiments were performed on the magnetic exposure of
the forearm of an exposed human subject. During exposure to a magnetic field, the bioimpedance
change signal level increases above the normal level, and reaches the maximum
level after about 10 minutes. The maximum value is approximately 50 % higher than the
normal level.
