Q:

How do cell phone radiation levels work?

A:

Quick Answer

Cellphone radiation is a type of non-ionizing radiation, typically thought of as a safe kind of radiation, and a form of electromagnetic radiation that falls somewhere near where microwaves are found on the electromagnetic spectrum. Cellphone radiation is emitted from the phone at varying levels depending on the model, and it is measured at a specific absorption rate, or the rate at which human tissue absorbs the incoming radiation.

SAR, or specific absorption rate, is measured as a comparison of the energy found in human tissue before and after exposure to electromagnetic radiation. These levels are considered safe below a certain threshold in a sample of human tissue, such as skin. Cellphones must meet a standard related to this, which keeps them safe for consumer use, with organizations such as the Federal Communications Commission monitoring the manufacturing of these products.

According to an article published in Scientific American, cellphone radiation may have benefits as well. Mice exposed to radio waves, such as those emitted from cellphones, were shown to have stronger memories as they aged. This comes as physical proof that contradicts the claims cellphone companies have made that their products do not have the emission strength to have physical effects, but not all effects seem to be damaging.
