游离辐射 Ionizing radiation

（重定向自Radiotoxic）
电离辐射的标志。此标志的含义是“当心电离辐射”，预示着标志挂放处可能存在被辐射照射的危险。
非电离辐射的标志。

游离辐射（英语：ionizing radiation）是指波长短、频率高、能量高的射线（粒子或波的双重形式）。辐射可分为游离辐射和非游离辐射，游离辐射可以从原子或分子里面电离过程（Ionization）中作用出至少一个电子。反之，非游离辐射则不行。游离能力，决定于射线（粒子或波）所带的能量，而不是射线的数量。如果射线没有带有足够游离能量的话，大量的射线并不能够导致游离。

Ionizing radiation hazard symbol
Alpha (α) radiation consists of a fast-moving helium-4 (4He) nucleus and is stopped by a sheet of paper. Beta (β) radiation, consisting of electrons, is halted by an aluminium plate. Gamma (γ) radiation, consisting of energetic photons, is eventually absorbed as it penetrates a dense material. Neutron (n) radiation consists of free neutrons that are blocked by light elements, like hydrogen, which slow and/or capture them. Not shown: galactic cosmic rays that consist of energetic charged nuclei such as protons, helium nuclei, and high-charged nuclei called HZE ions.
Different types of electromagnetic radiation
The total absorption coefficient of lead (atomic number 82) for gamma rays, plotted versus gamma energy, and the contributions by the three effects. Here, the photoelectric effect dominates at low energy. Above 5 MeV, pair production starts to dominate.

Ionizing (or ionising in British English) radiation is radiation that carries enough energy to free electrons from atoms or molecules, thereby ionizing them. Ionizing radiation is made up of energetic subatomic particles, ions or atoms moving at high speeds (usually greater than 1% of the speed of light), and electromagnetic waves on the high-energy end of the electromagnetic spectrum.
