Specific Absorption Rate (SAR)

Specific absorption rate is the measure of the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) in electromagnetic field. The term is not restricted to the absorption of Electromagnetic Feild (EMF) and can be used in terms of absorption of other forms of energy by tissue, including ultrasound. In short SAR is the power absorbed ..
