BACKGROUND There is an exponential growth of public concern worldwide regarding the exposure to electromagnetic fields (EMF) generated by wind turbines. The high concern of the general population enhances the fact that EMF exposure remains a crucial issue that demands specific actions and reliable data to evaluate possible health hazards. MATERIALS AND METHODS EMF exposure measurements were conducted in two wind farm (W/F) areas in Greece. The magnetic field strength concentrated in the proximity of 22 wind turbines (20 type of Gamesa Eolica Siemens of total power of 17 MW and 2 type of E53 Enercon, 800 KW each). Measurements were conducted using a Narda-NBM-550 basic unit (Narda Safety Test Solutions Company) using EHP-50F probe. The EMF exposure measurements were processed applying the weighted peak method (WPM), according to the 2013/35/EU Directive. WPM provides correction of the measured value of pulse signals, taking into account the phases of the various frequency components. The data were classified under two scenarios of EMF exposure: 'high wind' and 'low wind' conditions. RESULTS The variation of the magnetic field strength was calculated between 1.13 and 1.42% (WPM). Measurements indicate that the intensity of the emitted magnetic field at the base of the wind turbines, in both high and low wind conditions, was relatively low (mean = 0.146 μT), while decreasing rapidly with increasing distance and reaching background values 6 m from the base. CONCLUSION The results of the present study indicate that EMF levels are similar or even lower compared to those in urban areas and well below the national and international safety limits.

风力涡轮机附近的极低频电磁场测量。

背景技术在全世界范围内，关于由风力涡轮机产生的电磁场（EMF）的暴露的指数级增长。广大民众的高度关注进一步表明，电磁场暴露仍然是一个至关重要的问题，需要采取具体行动和可靠的数据来评估可能的健康危害。材料与方法在希腊的两个风电场（W / F）地区进行了EMF暴露测量。磁场强度集中在22台风力涡轮机附近（Games Eolica Siemens的20种类型，总功率为17 MW，E53 Enercon的2种类型，各自的功率为800 KW）。使用Narda-NBM-550基本单元（Narda安全测试解决方案公司）和EHP-50F探头进行测量。使用加权峰值方法（WPM）处理EMF暴露测量，根据2013/35 / EU指令。WPM考虑到各种频率分量的相位，可以对脉冲信号的测量值进行校正。在EMF暴露的两种情况下对数据进行了分类：“强风”和“低风”条件。结果计算得出的磁场强度变化在1.13和1.42％（WPM）之间。测量结果表明，在高风和低风条件下，风力涡轮机底部的发射磁场强度都相对较低（平均值= 0.146μT），但随着距离的增加而迅速减小，并从背景达到6 m。基础。结论本研究结果表明，与城市地区相比，EMF水平相近甚至更低，远低于国家和国际安全限值。
