摘要

背景:极低频电磁场(elf - emf)是由室内电器和电线产生的。2002年,国际癌症研究机构(IARC)将极低频磁场列为可能对人类致癌的物质(2B组)。因此,作为在德黑兰进行的首次研究,本研究的目的是调查2018年公众在住宅中暴露于极低频磁场的情况。方法:采用方便抽样法对102户家庭进行抽样调查。根据IEEE std 644-1994标准,使用TES-1393 EMF测试仪测量磁场。现场测量在三个不同的房间进行,包括厨房、客厅和卧室。结果:在住宅中测量的平均值为0.1µT。102个住宅的总磁通密度值与本底磁通密度值存在显著性差异。从厨房、客厅和卧室收集的磁场也没有显著差异。从不同距离的电视和计算机上采集的极低频磁场显示,随着距离源的增加,磁场磁场强度迅速减小。结论:根据统计分析,伊朗德黑兰的极低频磁场平均值与国际非电离辐射防护委员会(ICNIRP)提供的推荐值一致。

Survey of public exposure to extremely low-frequency magnetic fields in the dwellings
Background: Extremely low-frequency electromagnetic fields (ELF-EMFs) are generated from indoor electrical appliances and wiring. In 2002, the International Agency for Research on Cancer (IARC) classified ELF magnetic fields as possibly carcinogenic to humans (Group 2B). Therefore, the aim of this study as the first ever study conducted in Tehran was to survey the public exposure to ELF magnetic fields in dwellings, in 2018. Methods: In this study, 102 houses were selected using convenience sampling method. The magnetic field was measured based on the IEEE std 644-1994 standard using TES-1393 EMF tester. Spot measurements were done in three different rooms including kitchen, living room, and bedroom of each residential. Results: The average value of measurements taken in dwellings was 0.1 µT. There was a significant difference between total value of magnetic flux density and background level of magnetic flux density among 102 dwellings. There was also a non-significant difference among magnetic fields collected from kitchen, living room, and bedroom. The ELF magnetic fields collected from television and computer in different distances present that MFs decrease rapidly with increasing distance from the source. Conclusion: According to the statistical analysis, the average value of ELF magnetic field in Tehran, Iran, is the same as the recommended value provided by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
