variability is known as “measurement uncertainty.” When the FCC conducts post-grant testing of a cell phone, it takes into account any measurement uncertainty to determine whether regulatory action is appropriate.This approach ensures that when the FCC takes regulatory action, it will have a sound, defensible scientific basis.

The FDA scientific staff reviewed the methodology used by the FCC to measure cell phone RF,and agreed it is an acceptable approach,given our current understanding of the risks presented by cellular phone RF emissions. RF emissions from cellular phones have not been shown to present a risk of injury to the user when the measured SAR is less than the safety limits set by FCC (an SAR of 1.6 w/kg). Even in a case where the maximum measurement uncertainty permitted by current measurement standards was added to the maximum permissible SAR, the resulting SAR value would be well below any level known to produce an acute effect. Consequently, the FCC’s approach with measurement uncertainty will not result in consumers being exposed to any known risk from the RF emitted by cellular telephones.

The FDA will continue to monitor studies and literature reports concerning acute effects of cell phone RF, and concerning chronic effects of long-term exposure to cellular telephone RF (that is,the risks from using a cell phone for many years). If new information leads the FDA to believe that a change to the FCC’s measurement policy may be appropriate, the FDA will contact the FCC, and both agencies will work together to develop a mutually-acceptable approach.
