| 电离放射线 | ionising radiation Radiation that is capable of energizing atoms sufficiently to remove electrons from them. In this state atoms become more reactive, so that ionizing radiation increases chemical activity and in this way produces biological effects, including effects that involve alterations induced in DNA. X-rays and gamma-rays are the only electromagnetic waves that cause ionization in biological material (能够使原子充分通电并移除其电子的射线。在这种状态下原子的活性增强，因此电离射线可以增强化学反应性，通过这种方式可以产生生物效应，包括诱导DNA改变。X射线和伽玛射线是仅有的对生物材料造成电离的电磁波。) |
