You can't see it, taste it or smell it, but it's one of the most prevalent environmental exposures in the world today. Electromagnetic radiation (EMR) or electromagnetic fields (EMF) are the terms that describe exposures created by wired and wireless technologies that affect our lives today.
However, these technologies were never designed with biological effects on people in mind. Based on new studies, there is growing evidence among scientists and the public about possible health risks associated with these technologies. Research shows that humans are bioelectrical systems. Our hearts and brains are regulated by internal bioelectrical signals. Environmental exposures to artificial EMF's can interact with biological processes in the human body. In some cases, this can cause discomfort and disease. Since Word War II, the background level of EMF's from electrical sources has risen. Some examples of new technologies adding to our EMF exposure are: cell phones, wireless phones, Wi-Fi networks and more. Several decades of international science research confirms that EMF's are biologically active in animals and in humans and this could have a major public health effect.There are two different types of EMF's that we are exposed to: 1) Extremely low frequency electromagnetic fields (ELF). These come from electrical and electronic appliances and power lines. 2) Radiofrequency Radiation (RF) from wireless devices such as cell phones and cordless phones, cellular antennas and towers and broadcasting towers. Both of these are non-ionizing radiation, which means that they don't have enough energy to break off electrons from their orbits around atoms and ionize (charge) the atoms, unlike x-rays, CT scans and others. |
