Here are some possibilities:
1. Based on how it's emitted:
* Electromagnetic radiation: This covers a wide range of radiation, from radio waves to gamma rays, and is characterized by its wave-like properties.
* Particle radiation: This includes radiation that consists of particles like alpha particles, beta particles, neutrons, and protons.
2. Based on its source:
* Nuclear radiation: This refers to radiation emitted from the nucleus of an atom.
* Cosmic radiation: This refers to radiation originating from outer space.
3. Based on its effect:
* Ionizing radiation: This type of radiation can knock electrons off atoms, creating ions.
* Non-ionizing radiation: This type of radiation does not have enough energy to ionize atoms.
So, there isn't just *two* names for radiation. It's more accurate to say that radiation can be categorized in various ways.
Can you tell me more about what kind of names you're looking for? I might be able to give you a more specific answer.
