According to a group of 250 scientists, consumer products that emit specific radio signals may produce cancer risks due to the legal limits of electromagnetic frequency (EMF) radio waves within the products. Such products, according to the report, include “cellular and cordless phones and their base stations, Wi-Fi, broadcast antennas, smart meters, and baby monitors as well as electric devices and infra-structures used in the delivery of electricity that generate extremely-low frequency electromagnetic field (ELF EMF).”

Further, biochemistry professor Jerry Phillips, PhD, at the University of Colorado states that Bluetooth/wireless headphones, such as AirPods, could cause high levels of radiation to the user because they’re so closely worn to the ear canal. “My concern for AirPods is that their placement in the ear canal exposes tissues in the head to relatively high levels of radio-frequency radiation,” says Philips. “Effects include increased cancer risk, cellular stress, increase in harmful free radicals, genetic damages, structural and functional changes of the reproductive system, learning and memory deficits, neurological disorders, and negative impacts on general well-being in humans,” according to the expert.

As such, he alongside the group of experts have signed a petition to the United Nations and World Health Organization expressing “serious concern” about the risks and a strengthening of the pre-existing guidelines.

Other studies linking mobile devices and cancer have been debunked, however, another professor within the field (from the University of Pennsylvania) also states that the arguments have no credibility.

Apple has yet to make a statement.

In other tech news, Twitter has updated its camera to look more like Instagram.
