It's not radio active waves; it's just radio waves.
It's called the Ionosphere and depending on what layer of the Ionosphere it changes how far you can talk
The Ionosphere reflects longer radio waves back to Earth. It varies in height going up at night giving the waves a long distance bounce.Flat vertical walls. Better refraction will Non-ferous metals. Horizontal plan will distort the image of the wave.\ CIV
The ionosphere - specifically the e-layer
Ionosphere
Radio waves are in all parts of the atmosphere. Some, but not all, radio waves are reflected from the ionosphere, permitting transmission over greater distances.

The ozone layer contains electrical charged particles that reflects radio waves
The ionosphere is the layer of the atmosphere that reflects radio waves. This layer is able to reflect specific frequencies of radio waves back to Earth, allowing for long-distance communication using radio signals.
The "F" layer is high altitude region of ionized atoms that reflects radio waves.

The ozone layer contains electrical charged particles that reflects radio waves
X-rays and gamma rays, which have high energy levels, can be absorbed by the Earth's atmosphere and are unable to penetrate it. This absorption occurs mainly in the ionosphere, a layer of the atmosphere that reflects or absorbs these high-energy waves.
The thermosphere layer of the atmosphere can reflect certain frequencies of sound waves due to its high temperatures and density of charged particles. This allows for the propagation of long-distance radio communications known as skywave propagation.
If you are talking about short waves then the ionosphere.
No, it does not. Ozone only reflects UV rays.
