Researchers from the University of Essex have found no evidence that short-term health effects like headaches, rashes and nausea are caused by exposure to TETRA mobile radio masts. The two-and-half-year study, carried out at the University’s specially-designed Electromagnetics and Health Laboratory, is the first to report on short-term effects of TETRA mast emissions on human health and well-being. 

A total of 48 people who had previously reported sensitivity to mobile technology, and 132 control participants, were tested. Neither group could reliably detect the presence of a TETRA signal.  Participants were tested without knowing whether the signal was on or off (double-blind conditions). The researchers found there were no differences in physiological responses, or the reported severity of symptoms, between the on and off tests in either the sensitive or control groups.
