What is radiation?

Radiation is essentially energy traveling through a medium such as air, water, or space. Radiation can be divided into two categories. The first is electromagnetic radiation, which transports energy in the form of waves, such as radio waves or X-rays. The second is corpuscular radiation, which is composed of real particles as opposed to waves. Alpha particles, beta particles and neutrons are a few good examples.

Radiation can also be further divided into ionizing and non-ionizing radiation. This distinction depends on the energy of the radiation. Ionizing radiation has enough energy to remove electrons from atoms, creating ions. Non-ionizing radiation does not have enough energy to remove electrons but instead causes the atoms to move or vibrate
