In fact, there have been so many reports in Sweden that an epidemiological study is being undertaken. Does anyone know of headache studies being undertaken in the US? I think these headache reports are valid. Back in the 1960's when I found the microwave hearing effect, I carried out some studies in humans at incident average power densities of less than 1mw/cm2.* I was working at approximately what is now the cell phone frequencies. I discontinued that line of research with humans when I found that I was getting reports of headaches and I was experiencing headaches myself. (I don't get headaches). There was little known about headaches then and no good animal models for headache studies. Thus, at that time I could only report it in the literature as an incidental observation. * There is a microwave hearing effect that occurs at very low power densities and a skull vibration effect that occurs when very high energies are applied to the head. There is some confusion in the literature because the vibration effect has often been referred to as a microwave hearing effect, but it is not the same phenomena. Allan Allan H.
