This article investigates the electromagnetic field strengths and the resulting indoor exclusion zones (EZs), taking into account the actual indoor nuclear power plant (NPP) environment. To obtain the accurate indoor EZ, a real indoor environment based on the simulator room of Korea Institute of Nuclear Safety was included in the numerical simulation. The maximum distance d of the indoor EZs depending on the position and polarization of the emitter is 1 to 2.1 times longer than the distances d of the free-space EZs. To validate the simulated indoor EZs, electromagnetic field strengths along the arc line with an arbitrary distance from the emitter are measured in the NPP, which are in good agreement with the simulation results. The result demonstrates that the indoor EZ should be investigated before applying the wireless system in the NPP because the indoor EZ and free space EZ can be significantly different.

核电站电磁场传播与室内禁区分析

本文研究了电磁场强度和由此产生的室内禁区 (EZ)，同时考虑了实际的室内核电站 (NPP) 环境。为了获得准确的室内 EZ，数值模拟包括基于韩国核安全研究所模拟器室的真实室内环境。取决于发射器位置和极化的室内 EZ 的最大距离 d 是自由空间 EZ 距离 d 的 1 到 2.1 倍。为了验证模拟的室内 EZ，在 NPP 中测量了沿弧线与发射器任意距离的电磁场强度，这与模拟结果非常吻合。
