Because the mantle rock is opaque, most radiation (except for radioactivity from decay of uranium and other radioisotopes) cannot pass through it.
Radiation from radioisotopes (e.g. x-rays, gamma rays, beta rays) occurs in earth's mantle and can go significant distances before being absorbed by the rock, helping to keep the mantle hot.
The Earth's mantle is composed of solid rock that is not undergoing radioactive decay, which is the process that releases radiation. The radiation that is naturally emitted from the Earth mainly comes from the crust and the core, not the mantle. Additionally, the thickness and composition of the mantle act as a barrier that prevents most radiation from reaching the surface.
The movements of mantle rock is a classic example of thermal convection, though there will be some conductivity as well.

Hot, soft rock rise from the bottom of the mantle towards the top, cools, and sinks back through the mantle.

Radiation cannot occur in the Earth's mantle because the high density and pressure of the mantle material prevent electromagnetic radiation from propagating through it. Instead, heat transfer in the mantle occurs primarily through conduction and convection, with most of the heat generated by the decay of radioactive elements within the mantle itself.
The maximum wavelength at which electromagnetic radiation can occur is infinite.

No where.
Yes, radiation can occur in all three states of matter: solid, liquid, and gas. In solids and liquids, radiation can be absorbed or emitted by the atoms and molecules. In gases, radiation can also occur due to interactions between gas molecules and electromagnetic radiation.

Radiation exposure safety is the process of preventing or minimizing exposure to radiation, and tracking what does occur.
