一、γ射线料位计的测量原理和结构放射性同位素核衰变过程中能发射出各种不同的粒子。我们把单位时间内能够放射出来的粒子数或核的衰变数称为放射性强度。它的单位是居里,通常用毫居和微居。核衰变主要有α、β、γ三种。α衰变是核中放射出α粒子(即氦原子核);β衰变是从核中放射出带有负电荷的β粒子,也就是电子;γ衰变是从核中放射出一种电磁幅射, First, the γ-ray level meter measurement principle and structure of the radioactive isotope nuclear decay process can emit a variety of different particles. We call the number of particles that can be emitted per unit of time or the number of decaying nuclei as radioactive intensity. Its unit is Curie, usually with Habitat and Habitat. Nuclear decay mainly α, β, γ three. Alpha decay is emitted in the nucleus α particles (ie helium nuclei); β decay is emitted from the nucleus negatively charged beta particles, that is, electrons; γ decay is emitted from the nucleus of an electromagnetic radiation,
