BERLIN: Your wallet, your keys and – your mobile phone, of course! If you’re like most people, you never leave home without this trusty trio. But our attachment to our phones has sparked concerns that exposure to the radiation they emit is a health risk.
Mobile phones use radio-frequency (RF) electromagnetic fields to send and receive voice and text messages. Sometimes referred to as electromagnetic pollution or electrosmog, RF radiation is non-ionizing – it can’t break chemical bonds – but heats tissue in the area of the body where the phone is held, says Julia Ketteler, a research assistant at the German Federal Office for Radiation Protection’s (BfS) Competence Centre for Electromagnetic Fields.
