US mobile operator group, CTIA, has filed a suit against the San Francisco city government over a new law requiring retailers to display the radiation level of handsets on packaging.
The CTIA has accused the city of "unlawfully interfering with the FCC's exclusive, congressionally-derived authority over radio frequency emissions."
The CTIA noted that the FCC already publishes cellphone radiation limits or Specific Absorption Rate (SAR) limits on its website.
Proponents of the city's plan argue that the move will ultimately lead vendors to lower radiation levels. That seems unlikely since a SAR-approved phone is considered safe regardless of its official rating.
The bottom line is that most subscribers don't have a clue on radiation levels. This is a bit of an over-reaction since CTIA should have nothing to fear from consumers being more informed.
