211At是人工生产的，用于医疗目的。为了防止短寿命~(211)At的严重损失，需要一种快速分析放射性和所有化学形态的方法来进行相关的基础研究。我们提出了一种新的方法，即利用薄层层析和高灵敏度α摄像机组成的CCD光闪烁摄像系统。该系统的性能得到了实验验证：S在短时间内测量了低放射性~(211)At的56-672Bq，并对~(211)At的所有化学形态进行了评价。结果表明，该方法使我们能够在极短的时间内分析~(211)At的两个特征。
211At is artificially produced for medical purposes. To prevent severe loss of short-lived211At, a rapid method analyzing both the radioactivity and all chemical forms was required for related fundamental researches. We propose a new method by means of an α-scintillation-camera system comprising of thin-layer chromatography and a high-sensitive CCD camera. The performance of the system was experimentally verified: low-radioactivity211At of 56–672 Bq was measured in a short-time of 1000 s and all chemical forms of211At were evaluated. The results reveal that the method enables us to analyze two features of211At with significantly short-time.
