通过阻抗法对高分辨率人体解剖模型中的感应电流进行数值计算。人体模型应该暴露在来自家用感应加热器 (IH) 的高度不均匀的 20.9 kHz 磁场中。对于成人模型，在肩部和下腹部之间感应出 5 至 19 mA/m2 的电流。同时，对于儿童模型，在头部和腹部之间感应出 5 至 21 mA/m2 的电流。特别是脑组织附近的感应电流与腹部附近的感应电流几乎相同。当考虑中枢神经系统组织的感应电流时，在相同的B场暴露环境下，儿童模型的感应电流是成人模型的2.1至6.9倍。这些结果表明，对于使用 IH 的孕妇以及儿童（或站立高度较小的 IH 用户）进行进一步调查的重要性。
Induced currents in the high-resolution, anatomical human models are numerically calculated by the impedance method. The human models are supposed to be exposed to highly inhomogeneous 20.9 kHz magnetic fields from a household induction heater (IH). In the case of the adult models, the currents ranging from 5 to 19 mA/m2 are induced for between the shoulder and lower abdomen. Meanwhile, in the case of the child models, the currents ranging from 5 to 21 mA/m2 are induced for between the head and abdomen. In particular, the induced currents near the brain tissue are almost the same as those near the abdomen. When the induced currents in the central nervous system tissues are considered, the induced currents in the child model are 2.1 to 6.9 times as large as those in the adult model under the same B-field exposure environment. These results suggest the importance of further investigation intended for a pregnant female who uses the IH as well as for a child (or the IH users of small standing height).
