The brain is not a radio receiver for wireless phone signals: Human tissue does not demodulate a modulated radiofrequency carrier

It has been suggested that the low frequency modulations of the radiofrequency (RF) signal from a wireless phone could be demodulated by human tissue. If this occurred it could lead to interactions with ions in the tissue, with possible biological consequences. In recent experiments it has been shown that biological cells do not exhibit significant electrical nonlinearity to be able to demodulate low frequency signals present as modulations of a RF carrier. This makes irrelevant any hypothetical interactions between RF electromagnetic waves and biological systems involving such demodulation mechanisms. Your wireless phone is not an athermal hazard to your brain. (C) 2010 Academie des sciences. Published by Elsevier Masson SAS. All rights reserved.
