This survey of the activities of the Activation Analysis Section covers the period July 1969 to June 1970. An overview of the progress made by the various projects in the Section is given. A discussion of the operating characteristics of the NBS Reactor for activation analysis is given and the research activities of the various projects are discussed. Special attention is given to the many practical problems encountered by the Section during the year, and the results of the solutions to these problems, especially the analysis of Trace Elements in Glass Standard Reference Material (SRM) and of the botanical SRM. The quantitative analysis for boron using the nuclear track technique is discussed as well as extension of the analysis for uranium using this technique. An extensive discussion of the value of 3-MeV neutrons in neutron generator activation analysis and the experimental parameters for using these neutrons is discussed. The new target and pneumatic transfer systems at the NBS LINAC for photon activation analysis are described and the application of photon activation analysis for determining thallium in glass and high purity metals and gold, manganese and iron in high purity cadmium is discussed. Research into determination of nitrogen by photon activation analysis is described. A computer program, ALSPIS, for peak finding and integration is described and the application of a mini-computer to the Activation Analysis Section is noted.
