The aim of the course is to make students familiar with the topics of radioanalytical method of neutron activation analy-sis and activation measurements. Students will acquire detailed knowledge on neutron-induced nuclear reactions, neu-tron sources, neutron spectra, nuclear data and tools useful for activation techniques. They will get detail knowledge on procedures of neutron activation analysis, individual methods and types of activation analysis, and wide applications of this radioanalytical method in physical sciences and humanities. The working procedures of neutron activation analysis, its utilization for neutron field spectrometry, measurement of cross-sections and fission yields, and nuclear data valida-tion will be described in detail. Students will routinely work with semiconductor gamma spectrometers, they extend previously acquired knowledge on gamma spectrometry. They will perform activation measurements and composition analysis of various types of samples (historical, geological, environmental, biological) and neutron field parameters measurement necessary for determination of absolute thermal neutron flux and neutron spectrum. Students will acquire a wide practical experience with HPGe detectors, experimental work at the Training reactor VR-1, and neutron activation analysis in an interdisciplinary approach.
