Is it safe to sleep close to an electrical socket?

There is no evidence that can be scientifically proven that electricity (electric fields) is harmful at 50Hz. It may become dangerous at radio frequencies, getting worse as the frequency gets higher, with high power sources, but this is due to tissue heating as in a microwave oven. There is not a lot of radiation from a bit of T&E, and the story is very unlikely. The wavelength of 50Hz is around 6000 km, so the body is really tiny compared to it, and the voltage gradient across the body likewise tiny, even under a 400 kV line. One can easily light a fluorescent tube under those lines, but that is just the electric field to ground (say 50m and 400kV, so about 8 kV/m field strength, give or take. Even this is not usually considered harmful. Please don't tell her that the kitchen is probably the closest she will get to lots of electricity, her partner will not be pleased with the cooking work!
