Reflections on the INTERPHONE Study of Cell Phones and Brain Cancer
Many people cannot imagine life without a cell phone. Since commercial cell phone networks were first introduced in the 1980s, over half the world's population now uses them. While becoming a way of life and work, the radio frequency (RF) waves from cell phones have also been depositing energy into users' brains. With billions of people exposed to more RF energy than ever before, scientists and the public have asked if a lifetime of cell phone use might be a health risk.
