Philadelphia, the city of brotherly love has it. Many in San Francisco want it...
Wireless broadband Internet access (WiFi) seems too good to be true. At relatively low cost, anyone can get on the Internet anywhere in a city. All the city needs to do is install WiFi antennas.
An argument in favor of citywide WiFi is that it will reduce the digital divide: the poorer you are, the more limited your access to the Internet and its information resources. Cities like Philadelphia and San Francisco are actively trying to close the digital divide. One option is WiFi.
Yet in weighing the options, virtually nothing is heard about the potential health risks. Saturating an entire city with WiFi adds to the existing burden of nonionizing radiation. That burden, called electrosmog by some, consists of long-term exposure to low-level concentrations of nonionizing radiation from familiar sources like radio and TV signals, electronic and electrical devices, and the ubiquitous cell phone.
