β粒子:一种高速电子或质子,主要在放射衰变中释放出。
Beta particle: a high-speed electron or positron especially one emitted in radioactive decay.
β衰变过程使母核增加或减少一个单位的正电荷而不改变它的质量数。虽然与γ衰变或α衰变相比,β衰变是一个较慢的过程,但β粒子的穿透距离要比α粒子的大几百倍。β衰变的半衰期为几个毫秒或更长。
The process of beta decay increases or decreases the positive charge of the original nucleus by one unit without changing the mass number.though beta decay is in general a slower process than gamma or alpha decay beta particles can penetrate hundreds of times farther than alpha particles.beta decay half-lives are a few milliseconds or more.see also radioactivity.
