摘　　要：KJD-2000Rα谱仪是采用半导体探测器、利用核谱测量技术与嵌入式技术研制的新型测氡仪,是一种简便快速的测量氡气及氡子体的仪器。该仪器利用静电收集氡衰变子体进行测量,体积小,灵敏度高,操作方便,还可进行连续测氡与瞬时测氡以及α谱的测量。将该仪器用于地震流体监测,并总结出了测量在理论认识和实际应用中存在的问题,讨论了氡监测的原理和实践经验,以有助于促进氡测量方法的发展。A new alpha spectrometer, model KJD -2000R with the semiconauctor, was manufactured with the technology of the nuclear spectrum acquisition system and embedded system. The spectrometer works based on the electrostatic-coUection method. It has high sensitivity, small volume and easy to operate. The spectrometer can measure radon and radon daughters in a simple and fast way. It can be applied to the continuous measurement, instantaneous measurement, a-spectrum measurement and the underground fluid monitoring.
