Study of safety evaluation method for statistically varying wide frequency range of electromagnetic fields.

在大型螺旋装置（LHD）等磁聚变等离子体测试设备周围，对暴露于宽频率静态、低、高电磁场等突发事件的职业安全进行了测量。利用谱仪分析了随时间变化的统计变电场和磁场，并建立了包括个人监测器在内的探头连续监测系统。在分析中模拟了人体暴露分布，并讨论了健康和安全问题。

Concerning occupational safety by burst like exposure to wide frequencies of static, low and high electromagnetic fields had been measured around a magnetic fusion plasma test facility like the Large Helical Device (LHD). The time-dependently and statistical varying electric and magnetic fields were analysed by spectrometer and continuous monitoring system by using some probes including the personal monitors were established. Also human exposure distribution was simulated in analysis, and health and safety issues were discussed.
