Unless you're a tech-hating Luddite, there's a good chance you'll have a smartphone pressed up against your face on a daily basis. Ever since mobiles became commonplace in the late '90s, the medical community has raised concerns regarding the negative effects of prolonged phone usage. Thankfully, a new study suggests the type of radiation smartphones emit really isn't that harmful to humans.
Sadly, the same can't be said for rats. A recent US study saw both male and female rats exposed to radiofrequency radiation, with incidents of cancer springing up in the former. The rats were exposed to the sorts of radiation outputted from 2G and 3G connections, and after frequent nine-hour bouts of full-body exposure, some of the males developed tumours around their hearts.
Scientists don't seem to be overly concerned with what these results could mean for us squishy humans, though. Speaking to the Associated Press, Otis Brawley, who is the American Cancer Society's chief medical officer, downplayed the link between regular phone usage and cancer:
“The evidence for an association between cellphones and cancer is weak, and so far, we have not seen a higher cancer risk in people... I am actually holding my cellphone up to my ear.”
We're all reassured, right? Still, if you have pet rats at home, you should probably resist the urge to shove your iPhone against their furry little faces.
