We dismiss claims about mobiles being bad for our health – but is that because studies showing a link to cancer have been cast into doubt by the industry?

On 28 March this year, the scientific peer review of a landmark United States government study concluded that there is “clear evidence” that radiation from mobile phones causes cancer, specifically, a heart tissue cancer in rats that is too rare to be explained as random occurrence.

Eleven independent scientists spent three days at Research Triangle Park, North Carolina, discussing the study, which was done by the National Toxicology Program of the US Department of Health and Human Services and ranks among the largest conducted of the health effects of mobile phone radiation. NTP scientists had exposed thousands of rats and mice (whose biological similarities to humans make them useful indicators of human health risks) to doses of radiation equivalent to an average mobile user’s lifetime exposure.
