This paper evaluates the currents induced in the human body when exposed to extremely low frequency (60 Hz) electric fields by numerical modelling with boundary elements. The exposure is driven by the voltage of a rectangular panel representing the control keyboard of a power substation room. The main focus is to study the variations of the current density in the human body when located at different distances from the panel. In addition, the sensitivity of the results for the current density when considering the human body with and without its internal organs is estimated. The numerical approach is based on the three dimensional boundary element method (BEM) with the kernel of Laplace equation, in which the human body model considered is a simplified representation which allows parametric modifications of its geometry and physical properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
