Living near Power Lines - should I use EMF Paint to shield my home?

I have measured around 5mGauss of EMF inside my home from a nearby high power line. I've read about EMF Paints such as CuPro-Cote and Y-shield that can create an EMF shield. Before spending hundreds on this paint, does anyone know if it works? Are their any other ways to shield your home/family from EMF?
