INDUCED ELECTRIC CURRENTS IN MODELS OF MAN AND RODENTS FROM 60-HZ MAGNETIC-FIELDS

Induced electric currents in models of man, rat and mouse from 60 Hz m agnetic fields are computed using the impedance method. The models all have realistic shapes, and in the case of rodents, a homogeneous aver age tissue conductivity is assumed. The model of man is analyzed for t wo cases, a homogeneous average tissue conductivity and a heterogeneou s model, both consisting of 1.3 cm cubical tissue cells whose conducti vities are representative of the tissue within the cube. The results f or various models and species, as well as different orientations of th e magnetic field, are compared. The data presented are useful as the f irst step in dosimetry for 60 Hz magnetic fields, and for interspecies scaling of biological interactions related to the tissue induced elec tric currents.
