The secret to diagnosing ES is to expose the subject to only one type of EMF at a time , without confounding factors such as screen flicker, chemical outgassing, or auditory and visual cues that the subject may have come to associate with symptoms. This information is key to proper mitigation and avoidance techniques. The mystery of designing and selecting proper personal or architectural shielding is eliminated. Even the selection of the appropriate meter to determine EMF hot spots which would be trouble for you becomes obvious. Even if you find you are NOT sensitive to the fields produced by the kit, you have greatly narrowed down your search for the cause of your symptoms.
