Mobile phone companies are running on blood money, according to a leading scientist. Dr George Carlo claims the industry is ignoring and hiding evidence on the health risks of mobiles. After leading a £15 million research study into cellular safety, Carlo has written to the heads of every mobile phone company about fears that his scientific findings are being hidden. Carlo's current Wireless Technology Research (WTR) project is ending and he is moving into other public health areas. Speaking to The Guardian, he said: "The industry has known for a long time everything that I am saying. "It is alarming to me that they have taken so long in responding to he findings. They have sold another 25 million phones to people in the US alone since I raised these issues in February." Carlo found a higher rate of death from brain cancer in those using mobile phones. People using a mobile for at least six years doubled their chances of developing a benign tumour. He accused some companies of "repeatedly and falsely" claiming the devices were safe, and asked for safety leaflets to go out with every mobile sold. There are almost 20 million mobile phone users in the UK, with an average of two mobiles sold every second in the UK this summer. ®
