Wireless industry group sues San Francisco over new cellphone radiation law

CTIA, the lobbying arm of the wireless industry, is taking the city of San Francisco to court over a controversial new cellphone law. In a lawsuit filed July 23, CTIA is trying to block law that requires cellphone retailers in San Francisco to post in their stores each phone's "specific absorption rate," a measure of radiation absorbed by a user's body tissue that each manufacturer is required to register with the Federal Communications Commission. The CTIA said in a statement that it filed its suit in U.S. District Court in San Francisco because the law could mislead the public into believing that one phone is safer than another because of lower radiation levels.
