nuclear radiation
Nuclear radiation, or radiation as it is commonly known, exists in all substances, which is an objective fact and a normal phenomenon that has existed for hundreds of millions of years. Nuclear radiation is a stream of microscopic particles released by the nucleus in the process of changing from one structure or one energy state to another. Nuclear radiation can ionize or excite substances, so it is called ionizing radiation. Ionizing radiation is divided into direct ionizing radiation and indirect ionizing radiation.
A kind of energy emitted by radioactive substances in the form of waves or particles is called nuclear radiation. Nuclear explosions and nuclear accidents can produce nuclear radiation. Nuclear radiation is mainly alpha, beta and gamma rays. Alpha rays are helium nuclei, and the penetration ability of external irradiation is very weak. You can block it with a piece of paper, but it will be harmful if inhaled. β -ray is an electron flow, which burns obviously after irradiating the skin; Gamma rays have strong penetrating power and are short-wavelength electromagnetic waves.
