- Light is a form of electromagnetic radiation (EMR). The term light usually refers to visible light, but this is not the only form of EMR. As we will see, visible light occupies a narrow band in a broad range of types of electromagnetic radiation. Electromagnetic radiation is generated by a moving electric charge, that is, by an electric current.

Some types of radiation have enough energy that they can knock electrons out of their orbits around atoms, upsetting the electron/ proton balance and giving the atom a positive charge. Electrically charged molecules and atoms are called ions. The radiation that can produce ions is called ionizing radiation.

Electromagnetic radiation (EMR) consists of waves. The waves contain electric and magnetic energy. The electromagnetic spectrum (EMS) includes different types of energy waves. At one end of the spectrum, there are very low energy waves. Radio waves are an example of low energy waves. At the other end of the spectrum, there are very high energy wave...
Radiation can be either non-ionizing or ionizing. 1. Non-ionizing radiation doesn’t have enough energy to ionize atoms or molecules. That means it can’t cause atoms to gain or lose electrons. There are several types of non-ionizing radiation. They include near ultraviolet light, visible light, infrared radiation, microwaves and radio waves. Even if...
Particle radiation is made up of atomic or subatomic particles. These particles include protons, neutrons and electrons. They all have kinetic energy. That’s the energy is the energy an object has when it’s in motion. Both alpha particles and beta particles produce ionizing radiation. The charge they carry can remove electrons from atoms. They can ...
Mar 19, 2020 · Unlike the other kinds of radiation, there is no mass or charge. The amount of energy can range from very low, like in dental x-rays, to the very high levels seen in irradiators used to sterilize medical equipment.
Video. Test. Types of radiation. Three types of ionising radiation are: Alpha particle. particle \ (\alpha\) - is a helium nucleus, two protons and two neutrons. It has a large mass, compared...
Feb 22, 2024 · Key points. Ionized atoms can occur naturally in the environment and are considered unstable. Atoms seek to be stable and may release energy to become stable. The energy released from the atom is known as radiation. Overview. Ionizing radiation comes from radioactive atoms, many of which occur naturally in the environment.
Radioactive decay occurs when an unstable atomic nucleus emits particles or light waves. Isotopes are atoms of the same element (thereby having the same number of protons) which differ in the number of neutrons in their nucleus.
