beta particles (beta), also translated beta or shellfish particles, when the radioactive material beta decay, the release of high-energy electrons, the speed of up to 90% of the speed of light. In the process of beta decay, the radioactive nuclei are transformed into another by electrons and neutrinos, and the electrons in the product are called beta particles. In the positive β decay, a proton in the nucleus is transformed into a neutron, and a positive electron is released. In the "negative β decay", a neutron in the nucleus is transformed into a proton, while releasing an electron, that is, the beta particle Will release anti-micro-neutrons. Since the mass of the electrons is much lighter than the proton, the neutrons are much lighter, and when the β particles pass through an electric field, if it is negative electrons, the path is distorted in the direction of the positive pole. In the case of a magnetic field, if the direction of the magnetic field is from the inside to the outside, its particles will be twisted in counterclockwise direction, the path is curved, this distortion can be described using the right hand of the amperage: the thumb represents the direction of the magnetic field, the other four fingers on behalf of the negative Distort the path. ... β粒子（英语：Beta particle），又譯貝塔粒子或貝他粒子，指當放射性物質發生β衰變，所釋出的高能量電子，其速度可達至光速的90%。 在β衰变过程当中，放射性原子核通过发射电子和中微子转变为另一种核，产物中的电子就被称为β粒子。在正β衰变中，原子核内一个质子转变为一个中子，同时释放一个正电子，在“负β衰变”中，原子核内一个中子转变为一个质子，同时释放一个电子，即β粒子，也會釋放出反電子微中子。 由於電子的質量比質子、中子要輕得多，當β粒子通過一個電場時，如果那是負電子，其路徑會向正極的方向扭曲。在通過磁場時，如果磁場的方向是由內向外，其粒子會以逆時針方向扭曲，路徑呈弧形，這種扭曲可以利用安培右手定則描述：拇指代表磁場方向，其餘四指代表負電子的扭曲路徑。...
