The attenuation of ELF waves is so low that they can travel completely around the Earth several times before decaying to negligible amplitude, and thus waves radiated from a source in opposite directions circumnavigating the Earth on a great circle path interfere with each other.[20] At certain frequencies these oppositely directed waves are in phase and add (reinforce), causing standing wavesAt present, these bodies consider the scientific evidence related to possible health effects from long-term, low-level exposure to ELF fields insufficient to justify lowering these quantitative exposure limitsList of initialisms Skin effect TACAMO Wardenclyffe Tower Message OK Extremely low frequency (ELF)" Archived 21 July 2011 at the Wayback MachineIt is known that acute exposure to ELF EMF at high levels can affect the function of the nervous system27 (4): 53446Kraimer (May 1993)(Non-Ionizing Radiation) AAASThe Times of IndiaABibcode:2003R&QE.46.909BNaturally occurring ELF EMF is associated with atmospheric processes such as ionospheric currents, thunderstorms and lightningPropagation[edit]^ Coe, Lewis (2006)6 April 20101 June 2007^ GC.ca ^ "Expertise de l'Afsset sur les effets sanitaires des champs lectromagntiques d'extrmement basses frquences" (in French)pp.10.2510.27Retrieved 2007-06-02Retrieved 17 February 2012Health effects related to short-term, high-level exposure have been established and form the basis of two international exposure limit guidelines (ICNIRP, 1998; IEEE, 2002)Other uses[edit]^ "Extremely Low Frequency"Schumann resonances[edit]Titan's surface is thought to be a poor reflector of ELF waves, so the waves may instead be reflecting off the liquid-ice boundary of a subsurface ocean of water and ammonia, the existence of which is predicted by some theoretical models"Individual subject sensitivity to extremely low frequency magnetic field"^ Extremely Low Frequency Fields Environmental Health Criteria Monograph No.238, chapter 5, page 121, WHO What are the effects of exposure to ELF electric and magnetic fields?
