A number of my relatives believe that radiation from cell phones is dangerous. After doing a bit of reading, I've found that the general scientific consensus is that this is not the case, and I myself don't see how low power, low frequency, non-ionising radiation can cause e.g. brain tumours - at least, not by directly causing stress to DNA. However, there are still a few papers which conclude that cell phone use can cause health problems, e.g. lots by Hardell, and a few by others as well. This article, though it does not seem the best source of information (by far), suggests that the radiation indirectly causes health problems by inciting harmful 'biochemical responses in the cell'. Is a nondirect effect of cell phone radiation on health plausible? Are long term effects plausible? (Long term exposure is also something they are fixated on.) They are still adamant on keeping phones at a distance, regardless of my (possibly poor) attempt to explain why (I think) the radiation is harmless. They call it a precaution, 'just in case something turns out to be harmful'. My secondary question is: What sort of effects would sleeping in the same room as a charging phone have? I doubt there is anything drastic, but a relative frowned upon it and claimed some sort of increased electric field and long term effects etc. which I don't buy; but, at the same time, I don't know enough to give a confident response.
