Radiation defined

All these are radiations and forms of radiation classified into ionizing and non-ionizing. Ionizing because it produces electrically charged particles called ions in the materials it strikes, non-ionizing because it does not carry enough energy to ionize atoms.

So, radiation is defined thus:

• Energy in the form of waves or particles that has enough force to remove electrons from atoms.

• It includes particles and rays given off by radioactive materials, stars, nuclear reactions, and high voltage equipments.

• Most of it occurs naturally and some are produced by human activities.
