By ANSYS, Inc.
This application models the specific absorption rate (SAR) distribution in a human head, heart, and body exposed to an electromagnetic field emitted from a handheld cellular phone operating in GSM (900 MHz and 1,800 MHz) and GPS range in a partially closed environment. In the modeling, SAM Phantom IEEE model and a realistic human head and body are used to investigate both the local and average SAR of 1 g and 10 g tissue.
For a number of years, the general public has been concerned about the possible health effects of exposure to radio frequency (RF) radiation. High levels of RF fields are known to cause a variety of physical effects on the human body. With the dramatic increase in wireless device usage, particularly mobile telephones, R&D teams must ensure that products do not expose users to potentially harmful radiation levels.

.Why Samsung Cell Phones Are Rated The Lowest Radiation Cell Phones
Samsung adopted an innovative antenna system in 2006 to “enhance handset safety by radiating most of the transmitted RF energy away from the handset user” and improve RF (radio frequency) performance. Why haven’t more manufacturers followed suit?

RF Safe offers RF shielded flip cover cases and air tube headsets for the lowest radiation cell phones in 2014. Lowest SAR Samsung Phones Made Even Safer! Galaxy Note 2, Galaxy Note 3, Galaxy S3, Galaxy S4, Galaxy S5
(1) Why haven’t more manufacturers adopted modern antenna technology that both improves user safety and enhances cell phone performance?
