Like light, radiation has energy. When it passes through matter, it transfers and exchanges energy and interacts with matter. One of the main modes of action is to ionize or excite atoms in a substance, which is called ionization. Generally, we divide radiation into ionizing radiation and non-ionizing radiation according to its energy level or ability to ionize matter:
Non-ionizing radiation: refers to the radiation of low-energy substances that cannot be ionized, such as sunlight, lights, infrared, microwaves, radio waves, radar waves, etc. To
Ionizing radiation: Refers to radiation with high energy that causes matter to ionize.
Ionizing radiation is divided into:
(1) Particle radiation, such as α, β, neutron radiation, etc.;
(2) Wave radiation, such as gamma radiation and X-rays. To
Generally speaking, the so-called radiation or radiation refers to ionizing radiation.
