RF radiation from mobile phones didn't kill magnetite-containing bacteria, suggesting other phone emissions may be more biologically relevant.

Plain English Summary

Summary written for general audiences

Researchers exposed magnetic bacteria (bacteria containing magnetite particles) to radio frequency radiation similar to that emitted by GSM mobile phones to test whether RF signals cause cell death. They found no increase in bacterial mortality from RF exposure compared to sham (fake) exposures, suggesting that RF radiation alone doesn't kill these magnetite-containing cells. This challenges earlier findings that direct mobile phone exposure harmed similar bacteria, pointing researchers toward other components of phone emissions like low-frequency magnetic pulses.

Study Details

The aim of this study is to observe Exposure of magnetic bacteria to simulated mobile phone-type RF radiation has no impact on mortality.

A repeat of these experiments examining only the radio frequency (RF) global system for mobile commu...

Results indicate that the RF components of mobile phone exposure do not appear to be responsible for previous findings indicating cell mortality as a result of direct mobile phone exposure. A further mobile phone emission component that should be investigated is the 2-Hz magnetic field pulse generated by battery currents during periods of discontinuous transmission.
