| Abstract(in English) | Contact currents occur when a person touches conductive surfaces at different electric potentials. In the low frequency to intermediate frequency, The flow of current from an object to the body may result in the stimulation of peripheral nerves. Therefore, the reference level is regulated in terms of injected current in the international guidelines/standard. Contact current which does not produce induced quantities exceeding the basic restriction is used as a reference level. Some recent studies conducted dosimetry for contact current but only at extremely low frequencies. In our previous study we proposed a quasi-static finite-difference time-domain (FDTD) method which has a feature in its capability for handling realistic structures and source. This method extends a conventional FDTD method to solve quasi-static FDTD method for an ungrounded human body. Then the induced electric fields in the human body grounded and ungrounded are compared. The relationship between the basic restriction and reference level for contact current is discussed based on our computational results. |
