In this interview I had the pleasure to interview Mark Langdon, who is the founder and co-developer of Blushield EMF protection devices. Mark has been developing and working with EMF protection devices for over 25 years, and has designed and created some of the most sophisticated and effective EMF protection devices utilizing modern microprocessing technology.

Here is an interesting documentary on the effects of EMF radiation in our environment.  If you have a spare hour and a half this is well worth watching, and quite frightening.
