There is research showing that prolonged exposure to non-ionizing electromagnetic field radiation (EMF) may increase the risk of cancer as well as contribute to mitochondrial damage, headaches, vertigo, brain fog, and fatigue. There is also research showing that non-ionizing EMF radiation is harmless. My personal experience with it included some of the symptoms described in the former studies, and I've had a few clients whose symptoms (primarily chronic headaches,) went away once they removed themselves from high EMF areas.
For $35 plus $1 per mile if beyond a 7 mile radius from my office, I will travel to your home and test your household for EMF hotspots using a TriField meter. I like TriField because it tests radio and microwave radiation in addition to (and separate from) electric radiation and magnetic radiation.
Most EMF hotspots are located near WiFi routers, appliances in use such as portable heaters, dimmer switches, CFL lights, and microwaves, but occasionally it can also leak from wiring in the walls.
Payment for EMF testing is due upon my arrival and can be in the form of cash or credit card (the latter only if there is WifFi access).
For those interested, here is a link to an interview regarding the effects of EMF radiation, conducted by Dr. Joseph Mercola, of Paul Heroux, Ph.D., a physicist and professor of toxicology at McGill University:
