– NEW ProCon.org Website! – Are cell phones safe? – Cell phones use a form of radiation called radio frequency (RF) to send their signal. This RF radiation is regulated by the FCC, and has been deemed safe by a number of government and private scientific studies. However, some studies have found that the radiation from cell phones may increase the chance of developing cancer and other health problems. ProCon.org’s newest website explores the pros and cons of whether or not cell phones are safe to use.
