Metal dental work can more than double cell phone radiation absorption in head tissues, revealing how individual factors affect EMF exposure.

Plain English Summary

Summary written for general audiences

Researchers used computer modeling to study how metal dental work affects radiation absorption from cell phones held against the head. They found that certain types of metal dental crowns can more than double the amount of electromagnetic energy absorbed in nearby tissues when positioned parallel to the phone's antenna. Despite this significant increase, the radiation levels remained within current safety limits set by international health organizations.

Study Details

To investigate the influence of dentures on electromagnetic energy absorption during the daily use of a mobile phone, a high-resolution head phantom based on the Visible Chinese Human dataset was reconstructed.

Simulations on phantoms with various dentures were performed by using the finite-difference time-dom...

When the metallic dental crowns with resonance lengths of approximately one-third to one-half wavele...
