Is ELF (extremely low frequency) radiation emitted by the electrical appliances' battery's current considered to have adverse health effects, or is this radiation too low to be considered?

I'd like to keep the focus specifically on mobile phones and tablets, and please take in account that those devices are put on 'airplane mode' to eliminate the RF radiation emitted by 3g and Wifi.

Therefore this question address the effects of ELF only from a mobile phone or tablet running on battery.

The existence of some scientific papers show this may be a valid concern. For example,

  • Can you link us to a notable article or quote on this? – Rory Alsop Nov 10 '14 at 13:07
  • @RoryAlsop I arbitrarily referenced a couple of papers which I hoped may support that the question is notable. – ChrisW Nov 10 '14 at 13:47

    Thanks Chris - I've reverted my downvote. My quick google had only shown me a couple of very odd tinfoilhat websites... – Rory Alsop Nov 10 '14 at 14:18
  • @RoryAlsop I haven't read those papers. I'd like to assume that there's no risk at all, but, what do I know... – ChrisW Nov 10 '14 at 14:41

    I have a hard time believing this isn't a duplicate. Has this question _really_ not been asked before? It's such a common scaremongering claim... – Brian S Nov 10 '14 at 15:28
  • @BrianS I think it was asked yesterday quoting a page from the Mercola web site (but the quote from Mercola seemed too senseless to be answerable, so the question was closed and then maybe deleted). – ChrisW Nov 10 '14 at 16:02
  • Oh my. If such ELF was harmful, how could anybody survive NMR imaging? I'd estimate that if you scale the relative ELF intensity you receive in an MRT tube, compared to a mobile phone, to the phone's microwave emission, then this would correspond to an oven able to evaporate your body within seconds. Probably, even an ordinary permanent magnet would be a deadly weapon, if you throw it at somebody. — Hopefully, someone will reference a proper calculation of this. – leftaroundabout Nov 11 '14 at 12:54

    ["ELF" (i.e. extremely low frequency)](http://en.wikipedia.org/wiki/Extremely_low_frequency) is not microwave (the usual subject of these claims for cell phones) but much lower frequency and longer wavelength. Not that phones are going to be very efficient transmitters in this band: they simply aren't big enough to do a good job. But this looks like a distinct version of this kind of scaremongering, more closely related to high tension power-line claims than the usual cell-phone one. – dmckee --- ex-moderator kitten Nov 12 '14 at 01:10
  • @BrianS The question seems to be asked and answered here http://skeptics.stackexchange.com/questions/569/do-mobile-phones-have-anything-to-do-with-brain-cancer and here http://skeptics.stackexchange.com/questions/10239/can-radiation-from-wireless-phones-and-computers-harm-babies – Ellie Kesselman Nov 12 '14 at 12:58
  • @BrianS these posts are concerned with RF which are susceptible. I'm looking what happens when RF is cut off and you use the phone running on battery only,hence the ELF emitted – user3687001 Nov 12 '14 at 17:38
