Risk Assessment of Chronic Exposure to Magnetic Fields near Electrical Apparatus

Conferência: 9th International Symposium on Occupational Safety and Hygiene (SHO) Guimaraes, Portugal - FEB 14-15, 2013The paper presents a numerical model to calculate ELF magnetic fields for typical conductor arrangements of electrical power lines. After a presentation of the several sources of the magnetic field and an introduction to the problems arising from the continued exposure of human beings to low frequency magnetic fields, a description of the numerical model for the magnetic field evaluation is presented, discussing its application. The attention is then devoted to the analysis of possible solutions for magnetic field reduction.Portuguese Soc Occupat Safety & Hyg; Univ Porto, Fac Engn; Fac Motricidade Humana; Univ Politecnica Catalunya; TU Delft; Univ Minho, Sch Engn; European Network Safety & Hlth Profess Org; Int Social Secur Assoc; Latin Amer Assoc Work Safety Engn; Brazilian Soc Safety Engn; Spanish Ergon Assoc; Asociac Especialistas Prevenc & Salud Laboral; Galician Soc Occupat Risk Prevent; Brazalian Assoc Civil Engineers; Brazilian Assoc Ergon; Brazilian Assoc Occupat Hyg; Brazilian Assoc Prod Eng
