加速器质谱方法测量41Ca及其在生物医学中的应用

介绍了用AMS测量41Ca的方法及其在生物医学中的应用,以及中国原子能科学研究院目前开展4 1Ca的AMS测量及其应用研究的情况.Ca(T 1/2 =1.0×10 5 a) as a tracer, confined with Accelerator Mass Spectrometry (AMS) method and its applications are reviewed. Measurement of 41 Ca with HI-13 tandem AMS system at the China Institute of Atomic Energy is also introduced. The measurement of 41 Ca used for studying mechanism of cancer caused by carcinogenic substances and mechanism of Ca supplement in human body diseases are being developed in collaboration with Department of Occupational Health, Beijing Universit...     

Application of ^41Ca Tracer and Its AMS Measurement in CIAE

The man-made calcium isotope ^41Ca is an ideal tracer for the study of calcium metabolism. We represent the first application of accelerator mass spectrometry (AMS) measurement of ^41Ca tracer in China. The technique is being applied to the research field of cell messenger at the China Institute of Atomic Energy (CLAE). The sample preparation methods and the AMS measurements are discussed and some interesting results are presented.
