Waveguard is a small, oblong disc that is attached to the ear piece of the cellular phone with an adhesive pad. It requires no batteries or power source and can be used on any cellular phone on the market today. It is designed to absorb the potentially harmful stray electromagnetic radiation generated during the transmission and reception of cellular phone signals. Waveguard's design uses concentric circles of a highly conductive material that absorbs a majority of the stray electromagnetic radiation. Developed in South Korea, Waveguard's laboratory and field tests show the product absorbs more than 80 percent of electromagnetic radiation.
Cellular phones utilize electromagnetic waves to convey the voice signal.
The specific radio frequency that cellular phones utilize is very high and an energy source many medical experts believe can interfere with the body's central nervous system. In recent years, questions concerning health risks associated with exposure to electromagnetic radiation have arisen. As recently as January 1998, major newspapers quoted British bio-electromagnetic scientist Roger Coghill as saying cellular telephones should have a health warning. In 1985 there were 375,000 cellular phones in the United States. By 1995, that number had risen to more than 33 million, and today there are an estimated 55 million cellular phones in use.
