Often unaware of the potential risks to both library staff and the public, libraries have adopted wireless technology as a means to bridge the Digital Divide and in order to fulfill their mission under the Library Bill of Rights.
Research on the health effects of wireless technologies (2.4GHz and 5.0GHz bands) and electromagnetic (microwave) radiation indicates wireless technology, among other effects, may cause immune dysfunction, increased risk of brain tumors and acoustic neuromas, childhood cancers, breast cancer, Alzheimer’s disease (European Environment Agency, Bioinitiative Working Group, 2007), and genotoxicity. Research also indicates that public health standards are inadequate in offering guidance on the use of wireless technologies in community spaces.
