Abstract: 

REGARDING THE INCREASING DEVELOPMENT OF POWER LINES TRANSFORMATION IN THE WORLD AND INEVITABLE RADIATION EXPOSURE OF STUFFS OF POWER PLANTS AND ELECTRICAL DISTRIBUTION NETWORKS DUE TO MAGNETIC RADIATIONS THIS LINES, THERE FOR INVESTIGATING. THE EFFECT OF THESE MAGNETIC FIELDS ON CHARACTERISTICS AND FUNCTION OF VARIOUS TISSUES OF HUMAN BODY ESPECIALLY NERVOUS SYSTEM IN THE VIEW POINT OF THE HEALTH CARE OF THESE PERSONELS, IS NECESSARY. BASED ON THIS DEMAND, WE PROVIDE A STUDY ON THE INVESTIGATING EFFECT OF THESE POWER LINES MAGNETIC FIELDS ON PERIPHERAL MOTOR NERVES LATENCY.
IN THIS STUDY THE EFFECT OF EXTREMELY LOW FREQUENCY (ELF) WITH FREQUENCY OF 50 HZ AND THE POWER OF 10 MT THE LATENCY OF PERIPHERAL MOTOR NERVE OF MEDIAN IN 50 HEALTHY SUBJECTS (BY PUTTING THEIR LEFT WRIST BETWEEN TWO COILS OF HELMHOLTES BEFORE EXPOSURE AND AFTER EXPOSURE TO THE MAGNETIC FIELD. BY RECORDING WITH STIMULATORY AND ELECTROMYOGRAPHY DEVICES.
THE ASSAY OF EMG CURVES RESULTS, INDICATE THAT THE EXPOSURE OF MAGNETIC FIELD CAUSES A SIGNIFICANT (P<0.05) DECREASE IN LATENCY OF MEDIAN NERVE IN 84% OF SUBJECTS. DECREASING IN LATENCY MAY BE DUE TO THE ELECTRICAL CURRENT INDUCTION EFFECTS OF ELF FIELDS. THE RESULTS INDICATE THAT ELF FIELDS HAVE EXITABILITY EFFECT ON PERIPHERAL MOTOR NERVES.
