Background and Objective: Effects of electeromagnetic exposure on different parts of neruous system and memory of humans and animals has been established. In spite of important human studies, animal studies have been more precise and comprehensive. Extremely low frequency electromagnetic fields (ELF, <300Hz), have been reported to induce a variaty of behavioral and physiological function change...
extremely low frequency (elf) and radio frequency (rf) electromagnetic field may affect biological systems by raising generation free radicals by decline activities of glutathione peroxidase dismutase or increase in the lifetime of free radicals with inhibited pretreatment of cells antioxidant like that alpha tocopherol. elf and rf electromagnetic field maycan damaged dna with raising level ...
Extremely Low Frequency-Magnetic Field (ELF-MF) Exposure Characteristics among Semiconductor Workers
Extremely Low Frequency Magnetic Fields Induce Spermatogenic Germ Cell Apoptosis: Possible Mechanism
The energy generated by an extremely low frequency electromagnetic field (ELF-EMF) is too weak to directly induce genotoxicity. However, it is reported that an extremely low frequency magnetic field (ELF-MF) is related to DNA strand breakage and apoptosis. The testes that conduct spermatogenesis through a dynamic cellular process involving meiosis and mitosis seem vulnerable to external stress ...
Extremely-low-frequency (ELF, 3-3000 Hz) and very-low-frequency (VLF, 3-30 kHz) waves generated by the excitation of the thermal cubic nonlinearity are observed for the first time at the High-Frequency Active Auroral Research Program high-frequency transmitter in Gakona, Alaska. The observed ELF and VLF field amplitudes are the strongest generated by any high frequency (HF, 3-30 MHz) heating fa...
the ever increasing rate of power consumption has led to an increase in public exposure to extremely low frequency magnetic fields (elf-mfs) and brought severe concerns about their health effects. considering previous studies and the facts about potential health effects of these fields, the present study aimed to evaluate the elf-mf flux densities from power distribution lines near hospitals i...
In order to clarify the activity of magnetic fields on their frequency against the body, inhibitory activity against vasomotion of mouse skin arterioles was observed using a intravital-microscope after exposing the mouse whole body to 0.46 mT magnetic fields of extremely low frequency (ELF-MF: 25, 50 and 100 Hz) and direct current (DC-MF) which are approximately 10 times as strong as terrestria...
