In large doses, radio waves, also known as radio frequencies, can disrupt biological functions and break down tissue. There is still much debate over whether or not the radio frequencies emitted from mobile communication devices and the systems that support them pose any danger.Continue Reading
Some studies claim that the radio emissions from power lines, microwaves and radio communications contribute to the growth of tumors and are linked to increased headaches and brain disorders in those with higher exposure. The Federal Communications Commission, which has backed several studies, follows a recommended specific absorption rate of 1.6 watts per kilogram of emission as the public limit of radio frequency absorption from mobile devices. The FCC states that there are no scientific links between cellphone radiation and any illnesses, but the commission's website does provide some tips to reduce exposure. Moreover, the FCC is required by the National Environmental Policy Act of 1969 to continue evaluating and reporting any potential hazards surrounding radio frequencies as they are discovered.
Any electronic device that operates within the radio frequency of the electromagnetic spectrum emits some radio waves, regardless of the presence of an antenna. Radio waves are electromagnetic radiation, but they fall within the category of non-ionizing radiation, meaning they are longer and less energetic wavelengths. Studies on the effects of long-term and close-proximity exposure are still producing mixed results.Learn more about Optics & Waves
