Gamma radiation
either by radiation, conduction, or convection.
blackbody radiation
No. While most infrared radiation is from the center of hot solid objects, some of it is not. The sun is plasma (not solid) and it emits infrared radiation. Also, infrared radiation can be emitted by the friction in between objects
Radiation physics and solid state physics.
Sure. But the thicker and more dense the solid is, the more radiation is blocked. A nice, heavy blocker of nuclear radiation is lead.
in solid liquid and gasses
Usually.
The Sun is a source of energy, electromagnetic radiation. When this radiation impinges on a solid or liquid, it causes the atoms of that substance to vibrate more rapidly. The increasing vibration is "heat", their temperature increases.
It would take several inches of solid lead to prevent gamma radiation from reaching you.
In radioactive solids, yes. Any solid material with a half life will emit radiation. Any solid material with unstable isotopes within it will also emit radiation. Heat is infrared radiation, and any solid will radiate heat when the temperature outside it is lower.
None of these, light is electromagnetic radiation different response: its really a plasma
