Genetic Effects of Nonionizing Electromagnetic Fields
نویسنده
چکیده
Nonionizing electromagnetic fields (EMF) have photon energy less than 10eV, a level not sufficient to produce ions by ejection of orbital electrons from atoms. The biological effects of two types of nonionizing electromagnetic fields are being studies intensely: extremely-lowfrequency (ELF) electromagnetic field and radiofrequency radiation. Extremely-low-frequency EMF covers the frequency range of 3 Hz to 3 KHz. The most intensely studied frequency is the power frequency of 50/60 Hz. Electric appliances and power lines emit 50/60 Hz EMF. Radiofrequency radiation (RFR) covers a frequency range between 10 KHz to 300 GHz. Different frequencies of RFR are used in different applications. For example, the frequency range of 5.4 to 16 KHz is used in AM radio transmission, while 76 to 108 MHz is used for FM radio. Mobile phone technology uses frequencies between 800 MHz and 3 GHz. And RFR of 2450 MHz is used in microwave cooking.

Low-frequency electromagnetic radiation had previously been thought to cause human injury only by generation of excess heat or by shock from direct contact with electric current. Information accumulating over the past few decades, however, suggests that nonionizing electric and magnetic fields associated with this radiation may be an environmental etiology in human disease. Human beings are aff...

Many biological effects of exposure to extremely low frequency electromagnetic fields(ELF-EMFs) have been documented, but little work carried out on plants. A meiotic study wasperformed on Brassica napus L as C3 plant and Zea mays L as a C4 plant exposed to electromagneticfields. Our investigations were focused on plants grown from wet pretreated seeds with3 and 10 mT for a 4 h exposure time an...

Aiming to investigate the possibility of electromagnetic fields (EMF) developed by nonionizing radiation to be a noxious agent capable of inducing genotoxicity to humans, in the current study we have investigated the effect of 910-MHz EMF in rat bone marrow. Rats were exposed daily for 2 h over a period of 30 consecutive days. Studying bone marrow smears from EMF-exposed and sham-exposed animal...
