Classification of Radiation
Radiation is classified into two broad groups:
- Ionizing radiation (IR):- capable of causing characteristic changes in atoms or molecules in the body which can result in tissue damage such as cancer. Examples of IR include x-rays and gamma rays.
- Non-ionizing radiation (NIR):- doesn't cause these characteristic changes, but can prompt molecules to vibrate. This can lead to temperature rises, among other effects. Examples of NIR include ultraviolet radiation in sunlight, visible light, light bulbs, infrared radiation, microwave energy and radiofrequency energy.
