In the real world, however, most people carry their phones close to their body, usually in a pocket. Many women tuck their phone right into their bra, which may be the absolute worst place for a woman to put it, as it could raise their risk of both heart problems and breast tumors, two leading risks of death for women.
Now, cellphone testing by the Chicago Tribune1 reveals several popular cellphones emit far higher levels of RF radiation than legally permitted, which has not only reignited discussions about safety but also led to the launch of at least one class-action lawsuit.
How Safety Limits Are Determined
The safe distance (listed in your cellphone manual) is based on your phone's specific absorption rate (SAR). SAR is a measure of how much RF energy your body will absorb from the device when held at a specific distance from your body, typically ranging from 5 to 15 mm, depending on the manufacturer.
