[The ecological-hygienic aspects of the study of industrial-frequency magnetic fields].

Magnetic fields of industrial frequency with magnetic flux density of 10 mkTl were studied for their effects on the morbidity pattern in the population of the settlement located in the vicinity of a high-voltage electric power line of 750 kV. A trend was noted towards increase in the incidence of nervous and endocrine diseases as well as metabolic disturbances and disorders of the immune system.
