Mobile communication systems are undoubtedly an environmental source of electromagnetic radiation (EMR). Although the direct health effect a cell phone to human is still elusive, unicellular organisms rather apparent. The aim this study was examine effects EMR on development bacterial biofilm. Microtitration plates with four strains Staphylococcus aureus were exposed field frequencies 1-5 GHz, ...

Radiofrequency electromagnetic field=radiation (RFR) covers a large segment of the electromagnetic spectrum and falls within the nonionizing bands. Its frequency ranges between 3KHz and 300GHz. Cellular phones, wireless transmission towers for radio, TV, and telecommunication, radar and many other applications emit RFR. Different frequencies of RFR are used in different applications. For exampl...

Children are increasingly using cell phones. "Family package" deals make it easy for parents to obtain phones for their children, and the phones provide parents with the comfort of easy access to their children. However, cell phones emit radio frequency (RF) radiation (Bucher & the Committee on Appropriations, 2010). While the government has deemed RF radiation to be safe, there is no current s...

INTRODUCTION Tinnitus is a multifactorial condition and its prevalence has increased on the past decades. The worldwide progressive increase of the use of cell phones has exposed the peripheral auditory pathways to a higher dose of electromagnetic radiofrequency radiation (EMRFR). Some tinnitus patients report that the abusive use of mobiles, especially when repeated in the same ear, might wors...

It is documented that electromagnetic emissions from mobile phones can interfere with brain's signal processing activity due to their oscillatory similitude to the inherent rhythms of the brain, akin to "electromagnetic interference" observed while using mobile phones in aeroplanes. At high power density levels, thermal effects occur, some of which can be attributed to heat induced stress mecha...

CONTEXT The dramatic increase in use of cellular telephones has generated concern about possible negative effects of radiofrequency signals delivered to the brain. However, whether acute cell phone exposure affects the human brain is unclear. OBJECTIVE To evaluate if acute cell phone exposure affects brain glucose metabolism, a marker of brain activity. DESIGN, SETTING, AND PARTICIPANTS Ran...
