what’s is radiation and does everything emit radiation?
In: 0
Radiation is a *very* general term. Almost anything that travels outward from a source and carries energy can be considered radiation. Even sound is frequently considered radiation.
Oddballs like gravitational waves and sound aren’t usually talked about categorically as radiation, and are instead referred to specifically. The common types are particle radiation and electromagnetic radiation.
Particle radiation is fastmoving particles like electrons, protons, or even whole atoms. This is ionizing and can break molecules, so it is dangerous to humans.
Electromagnetic radiation includes so many different wavelengths, from radio waves to visible light to x-rays. These wavelengths act very differently, but share some similarities since they are fundamentally the same thing. Everything made of atoms generates this radiation as those atoms bounce against one another. This is how thermal cameras work.

There’s a few different kinds of radiation.
There’s electromagnetic radiation, which is basically light, everything from radio waves up to gamma radiation. X-rays and higher frequency waves are called ionizing, because they are powerful enough to knock electrons away from atoms, and will cause damage to living tissue.
Everything that has some heat (so everything), gives off some amount of electromagnetic radiation, mostly infrared radiation.
The other type of radiation is particle radiation, tiny bits of atoms that have gotten knocked free, and are moving really really fast. There are different types of particle radiation, groups of protons and neutrons (alpha), electrons (beta), and just plain neutrons. Each of them have different energies and will go through matter more easily.
Most matter has some small portion of its makeup that are unstable atoms. These atoms will spontaneously lose parts, and those parts are radation. Some matter (like uranium), is more unstable then others, and are more radioactive then others.
