This double-blind, counterbalanced cross-over study investigated whether extremely low frequency (DC to at least 40 kHz) fields emitted by GSM handsets affect resting EEG. In 72 healthy volunteers, the authors report a decrease in the alpha band during 20 minutes of ELF exposure in the exposed hemisphere only. They…

This animal study exposed 36 adult male guinea pigs to extremely low frequency electromagnetic fields at 5 Hz or 50 Hz and compared testosterone and testes tissue outcomes with sham/control conditions. After 5 days, the authors report a significant decrease in testosterone in exposed groups versus controls. They also…

This animal study examined rat ovaries after chronic exposure to a 3 mT low-frequency electromagnetic field for 4 hours per day over 4 months. Using TEM and TUNEL, the authors report ultrastructural alterations in oocytes and more frequent apoptosis-associated changes in granulosa and corona radiata cells versus…

This study reports measurements in 25 dental patients treated with the Viofor JPS system using extremely low frequency magnetic fields. Following a series of treatments, oral cavity electropotentials decreased and saliva pH increased. Copper levels in non-stimulated saliva decreased, while other measured elements…
[Evaluation of the genotoxicity of the extremely low frequency-magnetic fields (ELF-MF) in workers exposed for professional reasons].

Jan 1, 2007
This occupational study assessed whether extremely low frequency magnetic fields (ELF-MF) are associated with genotoxicity using cytogenetic assays in 109 workers. Comparisons across exposure strata, including a highest-exposed subgroup (TWA > 1 microT), found no significant differences in CA, SCE, or MN outcomes.…
Biological effects of extremely low frequency electric and magnetic fields: a review
Research

Jan 1, 1977
This review summarizes reported biological effects of extremely low frequency (ELF) electric and magnetic fields, describing them as significant and often acting as stressors. Reported outcomes include metabolic, hormonal, and body weight changes in rodents, lethality at high exposure levels in mice and insects, and…
