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, FCC's approach with measurement uncertainty will not
result in consumers being exposed to any known risk from the RF emitted
by cellular telephones.
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 FDA to believe that a
change to FCC's measurement policy may be appropriate, FDA will
contact FCC and both agencies will work together to develop a mutually-
acceptable approach.
