A pad or helmet at 25 milliwatts per square centimeter placed directly on the skin (zero distance) loses very little power through air scatter and remains nearly as powerful as a 178 milliwatt per square centimeter panel positioned 6-24 inches away, despite the apparent 7-fold difference in surface irradiance.
