You can stop wearing that aluminum foil hat while using your smartphone. A long-term study in the UK found that there is “no evidence of biological or adverse health effects” from using mobiles.

The report, officially dated 2012, is an 11-year program that, along the way, claims around 60 peer-reviewed journal papers. It also studied base stations and found that there is "no evidence that exposure to base station emissions during pregnancy affects the risk of developing cancer in early childhood, and no evidence that use of mobile phones leads to an increased risk of leukaemia.”

Professor David Coggon wrote that: “This independent programme is now complete, and despite exhaustive research, we have found no evidence of risks to health from the radio waves produced by mobile phones or their base stations. Thanks to the research conducted within the programme, we can now be much more confident about the safety of modern telecommunications systems.”
