Question 399

What is one way that RF energy can affect human body tissue?

  1. It heats body tissueBonne réponse
  2. It causes radiation poisoning
  3. It causes the blood count to reach a dangerously low level
  4. It cools body tissue

Explication

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.
