In response to Mark's request, I'd like to just bring in some general facts and personal observations concerning RF fields and biological effects. And also stick my head out with what I'm about to say.
RF radiation falls into basically three different categories in relation to its effect on things. (This is Doug speaking) The lower frequencies and longer wavelengths effect gross structures of things dependent upon a variety of factors that include geometry, dimensions, dielectric properties... Higher frequencies begin to effect the molecular structure of systems, and still higher freqs begin to penetrate the molecules and atoms themselves. When discussing RF fields and biological effects, the important thing to remember is the difference between "ionizing" and "non-ionizing" EM waves. Ionizing EM waves occur at extremely high freqs (up beyond the radar freqs). These can cause changes in molecules and can change gene structure. These freqs can cause changes in molecules and atoms more by their ability to penetrate these structures then effect the structure as a whole. Non-ionizing EM waves such as in microwave ovens don't cause molecular changes that have been observed at the very high freqs. For instance, the 2.45 GHz in domestic microwave ovens is capable of vibrating mainly dipole molecular structures such as water. The vibration of which causes heat and cooks (or burns as in my case) food. A large glass of water is a better target for absorption of RF energy than a drop of water. This is due to the size of the object and its associated rf absorption. These freqs effect the molecular or atomic structure is an entity more than its effects by penetration. What has never been resolved for me with the power line issues is whether or not the high voltage capable of ionizing surrounding mediums (i.e. air and such) is producing ionized material to which humans are exposed and have made various claims. In other words, I haven't been convinced that its simply RF or simply high voltage.
