A comprehensive study of exposure to the radiation emitted by mobile phones found an increased risk of a rare tumour in some rodents, although the scientist in charge cautioned against drawing conclusions about the impact on humans. 

Male rats developed heart tumours when exposed to high levels of a type of radiation used by the wireless telephone industry, according to the draft studies released Friday. Female rats and mice didn’t get the same tumours, the studies showed. Results were posted online.
