摘　　要：运用某些放射性核素在衰变过程中放射出β粒子激活发光材料发光的基本原理,利用能够放射出β粒子的核素种类和衰变数据及选用激发源的条件,确定了常用放射性的几种核素.选择出能用于β粒子激活发光的3种发光粉,制备出永久发光粉和红、蓝、绿3种氚灯.Introduced the principle of exciting the luminescent material to glow by β particle which is emitted by radionuclide. The nuclide category which can emit β particle, disintegration data, the condition of choosing the excitated source and the kinds of common radioactivity nuclide are presented. Three kind of the luminescent powder which can be activated by β particle is selected. The permanent luminescent powder and the new type of tritium lamp are manufactured by the principle of exciting the luminescent material to glow by β particle.
