Lots of people use their Mobile phones to read emails. They put the mobile phone in the pocket and it receives an email every couple of seconds. Every time an email is received the phone emits Electromagnetic radiation for several seconds. If they receive a lot of emails during the day then these seconds accumulate and the radiation doses can be large.
This video will show you that Electromagnetic Radiation is emitted from a Nokia E51 when receiving an e-mail.This file was send to me by "RoadFlyer" who was able to catch the moment
