摘　　要：介绍了一种基于静电扩散法的氡气测量装置的探测器总成,它采用由硅胶干燥器、双层滤膜、高压静电收集衰变室和微型气泵构成的采样气路收集氡,利用金硅面垒探测器,电荷灵敏放大器对衰变室内氡的子体进行探测,并配有峰值保持电路。It introduces a radon detector assembly of the radon measure device which bases on high voltage electrostatic diffuse approach.The radon is collected by a sampling air circuit which made of silicagel desiccator,double filter,high voltage electrostatic collecting decay chamber and micro-air pump.It detects the daughters of the radon which is in the high voltage electrostatic collecting decay chamber by Au-Si surface barrier detector and charge-sensitive preamplifier,and equips suitable peak hold circuit.
