The human body exposed to a magnetotherapy device magnetic field
This paper deals with human exposure to extremely low frequency (ELF) magnetic fields generated by a magnetotherapy device. The problem is twofold, i.e. it implies the assessment of an external ELF magnetic field and other internal parameters related to the human body response to this field (total current, power density, total power). Of particular importance is the current density induced inside the human body as the basic restriction proposed by relevant international bodies for non-ionizing radiation, such as ICNIRP. ELF magnetic field levels generated from a magnetotherapy device are obtained from measurement. Knowing the external magnetic field generated by a magnet, the circular current density induced in the human body is obtained by the use of the analytical formula arising from the disk model of the human torso. On computing the circular current density, it is possible to assess other parameters of interest related to body response. The obtained values of both the magnetic field and internal current density are compared to exposure limits in terms of reference levels and basic restrictions proposed by ICNIRP.
