Abstract

We have started the development of a transportable neutron salt-meter, we call it RANS-μ, combining a 252Cf neutron source and a prompt gamma neutron activation analysis. Trials of chloride detection measurement with RANS-μ were performed outdoor using removed bridges damaged by chloride attack at an outdoor yard in Public Works Research Institute (PWRI) and a test bridge in Fukushima Robot Test Field. For the measurement at PWRI, the results obtained by RANS-μ were compared with those of the automatic potentiometric titration by drilled powder, and then consistent results were obtained.

用于混凝土结构现场无损检测的中子盐计RANS-μ的研制

我们已经开始开发一种可运输的中子盐计，我们称之为RANS-μ，它结合了252Cf中子源和快速伽马中子活化分析。使用RANS-μ进行氯化物检测测量的试验是在室外进行的，使用的是公共工程研究所（PWRI）室外庭院中被氯化物侵蚀损坏的拆除桥梁和福岛机器人试验场的测试桥梁。对于PWRI的测量，将RANS-μ获得的结果与钻孔粉末自动电位滴定的结果进行了比较，从而获得了一致的结果。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
