There is extremely glaring factual mistake in this text. "And guess what wave frequency x-ray backscatter machines use? Hint: THz. http://arxiv.org/abs/0910.5294 http://arxiv.org/abs/0910.5294 Sorry. You missed by a multiplier of 10000-10000000. X-rays go from tens of petahertz to tens of exahertz. X-rays have frequencies way above visible light and terahertz waves have frequencies way below visible light. So this is quite glaring error. Is this intentional to increase doubts about x-ray backscattering or just a honest mistake? Just to clarify for everyone who requires some source for this claim: "X-radiation (composed of X-rays) is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3 × 1016 Hz to 3 × 1019 Hz) and energies in the range 120 eV to 120 keV." http://en.wikipedia.org/wiki/X-ray http://en.wikipedia.org/wiki/X-ray [EDIT] Removed few sentences which were written before morning coffee, the post was tad impolite before.
