What I am trying to get Ed among others to recognize is that high energy radiation from nuclear activity can be significantly downshifted in frequency by the same sub wave length nano-structures that produce the nuclear reactions in the first place.
Furthermore, the WL argument that energetic electrons can screen high energy radiation has not made an impression on people either. And then, when heat strongly interacts with electrons, these quasiparticles can modify the character of high energy EMF. When heat is developed in the lattice, gamma rays can be transformed into a lower energy radiation. Transmutation is a sure indicator that nuclear processes are afoot. Cheers: Axil
