放射性数据的水平分类研究是充分利用实验数据提供的情报,评价或解释实验结果是否有效的基本依据。它对实验方案的合理设计,测量系统的优劣比较,操作规程的质量控制,以及实验数据的预测估算等方面都有指导意义。 在文献上已见有这方面为数不多的研究报导。本文试图进一步把放射性数据的常规分析以更严格的形式把它们区分为放射性有—无临界水平、放射性可测定水平和放射性精确测定水平三级,通过引入源净计数可探测概率的定义,统一地给出各水平级的数学表示。还引进了极限精确度的概念和使用方便的极限制定规则。
The study of horizontal classification of radioactive data is the basic basis for making full use of the information provided by the experimental data to evaluate or explain the validity of the experimental results. It is instructive in the reasonable design of the experimental scheme, the comparison of the advantages and disadvantages of the measurement system, the quality control of the operating procedures and the prediction and estimation of the experimental data. There are a few studies reported in the literature. This paper tries to further divide the routine analysis of radioactive data into more rigorous forms of radioactively-non-critical level, radioactively measurable levels and precise level of radioactivity determination. By introducing the definition of probable probabilities of net source count, Give a mathematical representation of each level. Also introduced the concept of limit accuracy and ease of use to develop rules.
