What is one way that RF energy can affect human body tissue?
It heats body tissue✓Ճիշտ պատասխան
It causes radiation poisoning
It causes the blood count to reach a dangerously low level
It cools body tissue
Բացատրություն
RF fields induce currents in conductive tissue, and the resistive loss of those currents deposits energy as heat. Photon energy at radio frequencies is far below the threshold needed to ionise atoms, so radiation poisoning is not the mechanism involved.
