Female rats and mice didn’t get the same tumours, the studies showed. The rats received radiation over their entire bodies for nine hours a day for two years. The study found an increased risk of cardiac schwannoma, a tumour type that typically originates from cells found in neurons. Its guidelines set maximum radiation exposure levels based on the amount of heat emitted by mobile phones. The reports, along with earlier research show that current limits for mobile phone radiation, “remain acceptable for protecting the public health,” Jeffrey Shuren, director of the FDA’s Center for Devices and Radiological Health, said in an emailed statement.
