一、概述随着核技术的发展,放射性同位素和标记化合物在医学、生物学、工业、农业和科学研究等方面获得了广泛的应用。在应用工作中如何快速准确的进行定性、定量的测量分析是十分重要的。过去分析测量中采用的是分段测量等方法,这些方法灵敏度、分辨率都很低,误差也大,速度慢,操作人员的劳动强度大。国外在60年代发展起一种色层扫描法,它将被测样品用特别方法附在纸条上,然后在扫描机上分段扫描,获取的数据,描成射线强度谱,再进行分析处理得到所需的质量数据。随着电子计算机技术的飞速发展,
I. Overview With the development of nuclear technology, radioisotopes and labeled compounds have been widely used in medicine, biology, industry, agriculture and scientific research. In the application of how to quickly and accurately qualitative and quantitative measurement and analysis is very important. In the past, the methods used in the analysis and measurement were segment measurement. The sensitivity and resolution of these methods were very low with large errors and slow speed. The labor intensity of the operators was large. Abroad in the 60’s developed a color scanning method, which will be tested samples attached to the strip with a special method, and then scanned on the scanner section, the data obtained, described as the ray intensity spectrum, and then analysis and processing The required quality data. With the rapid development of electronic computer technology,
