You're not an antenna, you're a reflector. Just like you are a reflector for RFR at much greater power levels and much higher frequencies (light), yet only the highest energy ones(UV and above) cause cancer, and that is because they are of a sufficiently high energy that they are able to knock electrons away from atoms, turning them into ions(ionizing radiation).
