University of Essex - Hold the phones, it's fine

Researchers have found no evidence that short-term health problems such as headaches, rashes and nausea are caused by exposure to a type of mobile phone mast. A two-and-a-half-year study, carried out at the University of Essex's Electromagnetics and Health Laboratory, is the first to report on the short-term effects of emissions from terrestrial trunked radio (Tetra) masts. A total of 48 people who had reported sensitivity to mobile technology and 132 control participants were tested. The researchers found no differences in physiological responses when the Tetra signal was on or off.
