High-speed electric multiple unit (EMU) trains generate high-frequency electric fields, low-frequency magnetic fields, and high-frequency wideband electromagnetic emissions when running. Potential human health concerns arise because the electromagnetic disturbances are transmitted mainly into the car body from windows, and from there to passengers and train staff. The transmission amount and amplitude distribution characteristics that dominate electromagnetic field emission need to be studied, and the exposure level of electromagnetic field emission to humans should be measured. We conducted a series of tests of the on board electromagnetic field distribution on several high-speed railway lines. While results showed that exposure was within permitted levels, the possibility of long-term health effects should be investigated.
高速动车组列车运行时会产生高频电场、低频磁场以及高频宽带电磁辐射。由于电磁干扰主要通过车窗传入车厢内部，进而影响乘客和列车工作人员，因此引发了对人体健康潜在影响的担忧。需要研究主导电磁场发射的传输量和幅度分布特性，并测量电磁场发射对人体的暴露水平。我们在多条高速铁路线路上进行了一系列车内电磁场分布测试。虽然结果表明暴露水平在允许范围内，但仍应调查长期健康影响的可能性。
