can u tell when mobile phones go off?

[Marg0]

before they start ringing? i sometimes can, I've been told it's quite rare. Should i be worried about radiation exposure?

Yep, the radio makes a strange noise

return to sender.
i get a headache when i use my mobile. i hope they don't figure out 10 years from now that they're all incredibly dangerous, like they did with Tizer and beef and stuff.

Like televisions, alarm systems, computers, and all other electrical devices, mobile phones emit electromagnetic radiation.
Any powered speaker may make a sort of beeping sound before the mobile rings. It happens because the power supply to your speakers acts as an aerial, the signal (or more accurately parts of the signal)is picked up then causes the noise you hear.
Cell phones emit radiation- not gamma rays or x-rays but only non-ionizing micro waves which have lesser frequencies than even infrared rays.

thanks rob, maybe it's almost imperceptible, i don't recollect hearing anything, but I think it's going to ring, then it does. I saw on tv somewhere it was mentioned that a very small number of people can pick up some kind of change in the phone when this happens.
cheers.

Even I sometimes fancy I sense something before a person enters the room or the phone rings or something like that.
But I call it COINCIDENCE.
