^(36)Cl的加速器质谱测量及其应用

^(36)Cl AMS Measurement and Its Application

长寿命核素36Cl的半衰期为3.01×105a,广泛分布于自然界中。加速器质谱是目前测量36Cl的最灵敏的方法。介绍了36Cl的样品制备及加速器质谱测量方法,重点描述了基于小型化加速器质谱发展起来的测量36Cl的探测方法及其特点,综述了各实验室利用36Cl在相关领域开展的工作及所取得的成果。

The distribution of long-lived isotope ^36Cl （T1/2=3.01×10^5 a） is widely spread in the world.Accelerator mass spectrometry（AMS） is presently the most sensitive method for the measurement of ^36Cl.The sample preparation and AMS measurement procedure are briefly introduced.The detection methods based on the ＂small＂ AMS are also introduced,as well as their performance.The research progress on applications of ^36Cl in various laboratories around the world is reviewed.
