Why Do Scientists State That SAR Is Inadequate To Protect Cell Phone Users?

There are three major problems with the SAR laboratory compliance tests: (1) the models, (2) the method, and (3) the limits.

Inadequate Model: SAR Test Dummies Do Not Represent Human Cell Phone Users

SAR is not an adequate metric for understanding a person’s exposure as the test method is not representative of the actual people (from babies to adults) who use cell phones. The SAR test dummy is based upon a large adult male (6’2” tall and 220 pounds) called the Specific Anthropomorphic Mannequin, or SAM. 97% of the population is smaller than the SAM model, meaning that only 3% of cell phone users are represented. Research confirms that radiation absorption into a child’s head can be over two times greater, and absorption into the skull’s bone marrow can be ten times greater than adults.

The SAM head and body phantom is filled with a homogenous liquid. This liquid is not representative of the human body, which has dozens of different tissues—from eyes to muscles to bones—each of which has different electrical properties. Radiation moves in a more uniform fashion through SAM’s homogeneous liquid but does not move the same way though human tissues, which vary in thickness.

Scientists are concerned due to research that has shown in real mammal brains that cell phone radiation ricochets through the tissues and can form hotspots. Furthermore, the SAR laboratory compliance tests do not integrate various internal (e.g., piercings, metal implants) and external environmental factors (e.g., eyeglasses, metal walls) that could further impact the radiation absorption in a human body.

Inadequate Method:
