I have been going to an Infrared sauna to detox my body of heavy metals, using the Sunlighten infra red sauna, which uses carbon heaters. Now I am concerned that I am getting too much EMF Electro magnetic field from the carbon heaters. Does any one know which gauss meter should I use to test the amount of EMF in the sauna I use? Thank you very much. Susan Pratt Walton swalton@umich.edu
