In 1993, The AIHA Board of Directors adopted a position statement on human exposure to extremely low frequency fields. Since that time, members of the AIHA’s Nonionizing Radiation Committee have closely followed developments in this area including publication of significant studies of potential health effects and reports of expert panels. Based upon this information, the Nonionizing Radiation C...
The extremely low frequency (ELF) radiation from various laptops and monitors model was investigated using a cell sensor manufactured by Action Electronic, USA that is optimized to measure radiofrequency and extremely low frequency radiation. The ELF measured vary between 0.05 and 2.5 mG for all the laptops/monitors studied however, Hp Pavilion dv6000 laptop was considered to emit highest ELF i...
Paparan (radiasi) medan elektromagnetik Extremely Low Frequency (ELF) dicurigai berpengaruh terhadap kelainan otak. Tujuan penelitian ini adalah untuk menganalisis efek paparan ELF pada Metode yang digunakan metode article review dengan jumlah artikel 20 hasil relevan mulai dari tahun 2000 sampai 2022. Pada otak manusia, pengukuran selama 30-60 menit dalam intensitas 50 Hz tidak memiliki pengar...
Medan magnet Extremely Low Frequency (ELF) termasuk dalam radiasi gelombang elektromagnetik yang memiliki karakterisktik dengan spektrum rendah berfrekuensi 0-300 Hz biasa digunakan bidang pangan terutama pada proses fermentasi . Penelitian ini bertujuan untuk menganalisis potensi peningkatan kualitas apabila menggunakan medan (ELF). Metode penelitian yaitu Article Review Pengumpulan data dilak...
This paper surveys the instrumentation, calibration procedures, measurement techniques, and standards which can be used to characterize extremely low frequency (ELF) electric and magnetic fields. While the focus of the paper is on power frequency and power frequency harmonic fields, the measurement methods discussed are appropriate in principle for other ELF frequencies.
Introduction: Lack of high-quality sleep causes serious side effects like anxiety and changes in plasma concentration of oxalate. The current study aimed to investigate the impact of local extremely low frequency magnetic fields (ELF-MFs) on inducing sleep (sleepiness) and anxiety in male rats. Methods: In this experimental study, 40 male rats were allocated in four groups (n=10). The ELF-MFs ...
hypothermia generates potentially severe complications in operating or recovery room. forced air warmer is effective to maintain body temperature. extremely low frequency electromagnetic field (elf-emf) is harmful to human body and mainly produced by electronic equipment including convective air warming system. we investigated elf-emf from convective air warming device on various temperature se...
Magnetic fields have been reported to have shortand long-term effects on health, and epidemiological studies point to an increased risk of certain cancers after exposure to even low field strengths 2 . The International Agency for Research on Cancer (IARC) has classified so-called Extremely Low Frequency (ELF) magnetic fields (MFs) as a Class 2B ‘possible carcinogen’, whereas the evidence for E...
Background: The aim of this study was to assess exposure to extremely low frequency electromagnetic fields (ELF-EMFs) and its effects on secretion of thyroid hormones associated with symptoms of fatigue on electric arc welding workers. Methods: This study was carried out on two groups including 35 welders (as exposed) and 35 non-welders (as control). Extremely low frequency electromagnetic fie...
