摘要 长寿命的宇宙射线成因核素和人工生成核素如^14C、^10Be、^26Al和^129I等在环境科学具有非常重要的意义。然而,由于他们半衰期长,含量及其低(同位素丰度比在10^-10-10^-16范围)。采用传统质谱和放射性测量方法都不能够事先对其准确测量,目前只有加速器质谱(AMS)是最为有效的测量方法。本文介绍AMS原理、技术发展现状、测量方法以及在环境保护中的应用。 The Long-lived cosmogenic radionuclides and artificial radionuclides,such as ^14C, ^10Be, ^26Al and ^129I,havea very important significance in environmental science. However, above radionuclides have long half-life, and low content (isotope abundance ratio in the range 10-10-10-16). Using conventional mass spectrometry and radioactive methods are not able to accurately measure. Recently, accelerator mass spectrometry (AMS) is capability of effectivemeasurement. This article introduces the principle, technology development situation, methods of measurement of AMS and its application in environmental protection.
