The term describes cellular telephones that emit the least amount of radiofrequency (RF) energy absorbed by the body when in use. Specific Absorption Rate (SAR) is a measurement that quantifies this RF energy absorption, typically expressed in watts per kilogram (W/kg). A lower SAR value indicates reduced exposure to RF radiation during phone operation.
Limiting RF energy absorption offers potential health benefits, aligning with a precautionary approach to electromagnetic radiation exposure. Individuals may prioritize devices emitting lower levels of RF radiation, reflecting a desire to minimize any potential long-term health effects associated with cellular phone usage. The concept has gained traction as scientific understanding of RF radiation effects evolves, influencing consumer choices and manufacturer design considerations.
