Listen to pronunciation. (I-uh-NY-zing RAY-dee-AY-shun) A type of high-energy radiation that has enough energy to remove an electron (negative particle) from an atom or molecule, causing it to become ionized. Ionizing radiation can cause chemical changes in cells and damage DNA.
What is ionising radiation in simple terms?
Ionizing radiation is radiation with enough energy that to remove tightly bound electrons from the orbit of an atom, causing that atom to become charged or ionized.
What does Ionising mean?
Ionization or ionisation is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically charged atom or molecule is called an ion.
What is Ionising effect of radiation?
When ionizing radiation interacts with cells, it can cause damage to the cells and genetic material (i.e., deoxyribonucleic acid, or DNA). If not properly repaired, this damage can result in the death of the cell or potentially harmful changes in the DNA (i.e., mutations).
What is the difference between radiation and ionising radiation?
Radiation is classified as being either non-ionizing or ionizing. Non-ionizing radiation is longer wavelength/lower frequency lower energy. While ionizing radiation is short wavelength/high frequency higher energy. Ionizing Radiation has sufficient energy to produce ions in matter at the molecular level.
What causes Ionising radiation?
Ionizing radiation is generated through nuclear reactions, nuclear decay, by very high temperature, or via acceleration of charged particles in electromagnetic fields. Natural sources include the sun, lightning and supernova explosions.
What are the 3 types of Ionising radiation?
Types of Ionizing Radiation
- Alpha Particles. Alpha particles (α) are positively charged and made up of two protons and two neutrons from the atom's nucleus. …
- Beta Particles. …
- Gamma Rays.

What is ionising radiation HSE?
Ionising radiations occurs as either electromagnetic rays (such as X-rays and gamma rays) or particles (such as alpha and beta particles). It occurs naturally (eg radon gas) but can also be produced artificially.
