Smart Meter health risks and information that is not found easily on MAIN STREAM MEDIA TV, newspapers and magazines. There are several web sites that can be found quickly by using a search engine such as www.metacrawler.com and search using words "Smart Meter Dangers". One of the web sites I found most helpful http://http://www.smartmeterdangers.org and you can also search the names of Devvy Kidd and/or Dr. David Carpenter Dean at the University of Albany as part of search parameters.
Examples of dangers related are sleeplessness, headaches, ringing in head/ears, cancers, etc.
Note....You can refuse to have it installed if you know of it before hand and recently the electric companies have even been forced to remove them when health concerns have been noted.
