The workshop on "Multiple Prompt Gamma-ray Analysis" was held on February 19, 2008 at Tokai. It is based on a project, "Development of real time, non destructive ultra sensitive elemental analysis using multiple gamma-ray detections and prompt gamma-ray analysis and its application to real samples", one of the High Priority Cooperative Research Programs performed by Japan Atomic Energy Agency and the University of Tokyo. This report presents the papers and the materials of 9 presentations in the workshop.

A new trace element analysis method is proposed on the basis of multiple -ray detection, which is two or higher fold -ray coincidence method. We apply this method for prompt -ray activation analysis (PGAA) and instrumental neutron activation analysis (INAA). The advantage of the methods consists of high energy resolution and high sensitivity. The principle of the multiple -ray detection method and actual applications to cosmological chemistry, earth chemistry, environmental chemistry, etc, will be presented.

In this study, as a first step to understand the formation behaviour of gaseous iodine under Sodium-cooled fast reactor sever accident condition, gas evolution from sodium iodide (NaI) in an inert atmosphere was investigated using a Temperature Programmed Desorption-Mass Spectrometry (TPD-MS) apparatus. NaI is expected to be formed by reacting iodine as the fission product with sodium as the coolant. The result was suggested that thermal behaviour of NaI over about 660 Celsius degree was apparently phase change from solid to liquid/gas and formation of gaseous iodine was negligible in an inert atmosphere.
