摘要/Abstract

摘要： 放射性气溶胶监测方法主要有假符合法和能谱法, 能谱法又有超道补偿和双道补偿2种方式。本文对这3种监测方法的测量灵敏度进行分析和估算。

关键词: 放射性气溶胶监测, 测量灵敏度, 假符合法, 能谱法

Abstract: Both false coincidence methods and spectroscopic methods are mainly employed for radioactive aerosol monitoring, whilethere are two kinds of mode for the latter, i.e. super-channel and dual-channel compensations. The measurement sensitivity thereof is analyzed and estimated.The spurious coincidence and spectroscopy are mainly methods used for radioactive aerosol monitoring, furthermore the spectroscopy methods can be categorized as Super channel-energy compensation method and Double channel-energy compensation method. This paper analyzes and estimates the measurement sensitivity of thethree monitoring methods above.

Key words: Radioactive aerosol monitoring, Measurement sensitivity, False coincidence method, Spectroscopic method
