Do cellular phones pose health risks? The available scientific reports do not show that any health problems are associated with the use of wireless phones. On the other hand, however, there is no proof that cellular phones are absolutely safe. Wireless phones emit small levels of radiofrequency energy (RF) in the microwave range when being used. As well, cell phones also emit small levels of RF when in the main menu screen. While high levels of RF can produce health effects by heating tissue, low level exposure to RF that does not produce heating effects, cause no known adverse health effects while using cell phones. Many studies of small level RF exposures have not found any biological effects. Some studies suggest that some biological effects may occur, but these findings have not been confirmed by additional research. In other research, expert researchers have had problems in reproducing those studies, or determining the cause for the conflicting results with respect to wireless phones. We hope that we have been successful in reassuring our readers that there is no evidence to conclude that wireless phones pose health risks.
