Background: Effect of electromagnetic and radiofrequency fields on human health is not well understood, a concern is its effect on male infertility. With the increased use of modern technology, issue of protection against this fields has great importance. infertility is the problem to follow psychological - social consequences. The most common cause of infertility are: male factor, female facto...
background: the rapidly increasing use of mobile phones has led to public concerns about possible health effects of these popular communication devices. this study is an attempt to investigate the effects of radiofrequency (rf) radiation produced by gsm mobile phones on the insulin release in rats. methods: forty two female adult sprague dawley rats were randomly divided into 4 groups. group1 w...
Experimental studies that sought teratologic effects or developmental abnormalities from exposure to radiofrequency electromagnetic fields (RFEMF) in the range 3 kHz-300 GHz are critically reviewed for their possible consequences on human health. Those studies were conducted on beetles, birds, rodents, and nonhuman primates. Collectively, those experimental studies indicate that teratologic eff...
introduction : the fast-growing telecommunication and wireless technologies has led to more dependence to these communication devices and higher levels of exposure to electromagnetic radiations propagated by cellular devices and their service towers. to disable signaling in places where silence is valued or where information quarantine measures are required, mobile phone jammers emit radiofrequ...
introduction : the rapid development of wireless telecommunication technologies over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fi elds. nowadays, people are continuously exposed to different sources of electromagnetic fi elds such as mobile phones, mobile base stations, cordless phones, wi-fi routers, and power lines. therefore,...
In the electromagnetic spectrum, structural damage to living tissues per unit of absorbed energy tends to increase with the decrease of a wavelength which is evident not only for ultraviolet and ionizing radiation but also for the infrared and visible light. By causing thermal damage after absorbing energies that would be harmless for radiofrequency electromagnetic fields (EMF), tissues are eve...

In May, 2011, 30 scientists from 14 countries met at the International Agency for Research on Cancer (IARC) in Lyon, France, to assess the carcinogenicity of radiofrequency electromagnetic fi elds (RF-EMF). These assessments will be published as Volume 102 of the IARC Monographs. Human exposures to RF-EMF (frequency range 30 kHz–300 GHz) can occur from use of personal devices (eg, mobile teleph...
