Specific Absorption Rate
A measure of the amount of
radio frequency energy (radiation) absorbed by the body when using a
radio transmitter device such as a mobile phone.
with federal health and safety agencies, such as the Food and Drug
Administration (FDA), the FCC has adopted limits for safe exposure to
radiofrequency (RF) energy. The FCC requires cell phone manufacturers
to ensure that their phones comply with these objective limits for safe
exposure. Any cell phone at or below these SAR levels (that is, any
phone legally sold in the U.S.) is a "safe" phone, as measured by these
standards. The FCC limit for public exposure from cellular telephones
is an SAR level of 1.6 watts per kilogram (1.6 W/kg).
