today, there is an increasing interest in the use of metal nanoparticles in health sciences. amongst all nanoparticles, the gold nanoparticles have been known to kill the cancer cells under hyperthermic condition by near-infrared frequency electromagnetic waves. on the other hand, although there are different physiochemical methods for disinfection of microbial pollution, however applications o...
Worldwide Interoperability for Microwave Access (WiMAX), based on the IEEE 802.16 standards, is a technology that offers low cost mobile broadband access to multimedia and internet applications for operators and end-users. Similarly to cellular phone or other Radio Frequency devices, WiMAX has to be considered as a possible source of electromagnetic pollution and so monitoring its emission coul...
The environment is exposed to electromagnetic radiations as a result of widespread use of wireless communication. This yields a massive increase in electromagnetic pollution. There is a concern of possible adverse effects of cellular phone radiation as a result of the enormous increase in the use of these phones throughout the world. The potential risks of electromagnetic field (EMF) emitted by...
Introduction: The highest electromagnetic radiation pollution is related to the radiofrequency waves of mobile phones (1). Up to 70% of these waves can be absorbed by various tissues (2). Absorption of these waves can damage the body tissues by causing oxidative stress (3). Given that melatonin plays an antioxidant role, it seems that this hormone can have a protective effect on the hepato- tox...
A review on the impact of radiofrequency radiation from wireless telecommunications on wildlife is presented. Electromagnetic radiation is a form of environmental pollution which may hurt wildlife. Phone masts located in their living areas are irradiating continuously some species that could suffer long-term effects, like reduction of their natural defenses, deterioration of their health, probl...
BACKGROUND An increasing number of persons suffer from non-specific health symptoms such as headache, sleep disturbances, difficulties in concentrating and more. In lack of a medical explanation, more and more persons take refuge to the assumption that they were electromagnetic hypersensitive (EHS) and electromagnetic pollution causes their problems. The discussion whether electromagnetic field...
Life on Earth has formed and evolved under exposure to electromagnetic radiation (EMR) of the Sun, which is the most potent natural source of electromagnetic waves. Besides the Sun, electromagnetic oscillations form during lightning strikes. Also, there is geomagnetic background of our planet. Artificial electromagnetic radiation is produced by different electrical equipment, electric motors, r...
