I recently watched 2 excellent youtube videos that explained it very well:

Dark Side of Smart Meters, by Rob States: http://www.youtube.com/watch?v=FLeCTaSG2-U (30 minutes)

Scientist and PhD Martin Blank:

http://www.youtube.com/watch?v=5NdfYR2daAg (part 2–10:09)

For detailed peer reviewed reports, someone else may choose to post that or you can obtain those from researching the scientists in the #3 videos and read their reports and those of colleagues.
1. INSURANCE COMPANIES WON’T INSURE THE HEALTH PROBLEMS FROM WIRELESS Smart Meters

And Insurance companies don’t sacrifice insurance premiums ($$$) for no reason.

2. WIRELESS SMART METERS TRANSMIT RADIATION APPROXIMATELY 25,000 TIMES PER DAY, 24/7, not 45 seconds per day as claimed by PG$E.

3. CELL DAMAGE, DNA BREAKS and BREACHES IN THE BLOOD-BRAIN BARRIER observed in laboratory tests from low levels of pulsed RF signal radiation as emitted by Wireless smart meters – reported by Top Wireless radiation scientists in the world at the Commonwealth Club in San Francisco Nov 18, 2010:

4. FINALLY, THE KAROLINSKA INSTITUTE IN STOCKHOLM THAT GIVES THE NOBEL PRIZES PUT OUT A GLOBAL WARNING AGAINST WIRELESS SMART METER DEPLOYMENT and some other Wireless devices.
2-page Press Release:
http://www.scribd.com/doc/48148346/Karolinska-Institute-Press-Release

Comparing cell phones and Wireless smart meters is comparing apples and oranges. Simple signal strength comparisons of one device to another done by amateurs or PG&E Corporate talking heads are guiding many people into dangerous environments.

Wireless smart meters are unique in that they transmit 24/7 without shut off switch and without relief. Humans can recover from significant adversity and stress, but 24/7 pulsed transmissions from Wireless smart meters mounted to homes may interfere with the sleep time for human recovery and the pulsed signal radiation from the Wireless meters may interfere with the natural bio-electronic communications originating in the brain.

Thank you.

We have more problems on the horizon!!!

Well-written, easy-to-read article–thanks!

By the way, what is happening to the people who tell the meter installers not to install on their house and the installers don’t. Do those residents get threatened by PG&E? Are meters eventually being installed anyway?
