此图片显示了三种游离辐射之穿透性。α粒子可被纸张阻停。β粒子可被铝片阻停。γ射线在穿越铅屏时部分被阻。
电离辐射的标志
 电磁光谱

物理学上的辐射指的是能量以波或是次原子粒子移动的型态,在真空或介质中发送。包含:

辐射之能量会从辐射源往外向所有方向直线放射。一般依其能量的高低及电离物质的能力分类为电离辐射和非电离辐射。电离辐射所携带的能量大于10电子伏特(eV),可以将原子或分子电离、打断化学键,非电离辐射则否。主要电离辐射来源为放射性物质,放射出αβγ射线,分别带有氦核、电子、正电子、光子。其他电离辐射来源有医学影像造影使用的X射线、渺子、介子、正电子、中子,以及宇宙射线与地球大气作用所产生的其他粒子。

Radiation 辐射

Illustration of the relative abilities of three different types of ionizing radiation to penetrate solid matter. Typical alpha particles (α) are stopped by a sheet of paper, while beta particles (β) are stopped by an aluminum plate. Gamma radiation (γ) is damped when it penetrates lead. Note caveats in the text about this simplified diagram.
The international symbol for types and levels of radiation that are unsafe for unshielded humans. Radiation in general exists throughout nature, such as in light and sound.
Graphic showing relationships between radioactivity and detected ionizing radiation
The electromagnetic spectrum

In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes:

Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules, and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms. A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively. Other sources include X-rays from medical radiography examinations and muons, mesons, positrons, neutrons and other particles that constitute the secondary cosmic rays that are produced after primary cosmic rays interact with Earth's atmosphere.
