The purpose of the experiment is a demonstration of the relative neutron activation analysis technique (NAA). This technique is widely used in a variety of fields (e.g. environmental sciences, forensic science, analysis of geological and inorganic materials, foodstuff, etc.). It plays a key role within environmental specimen banking programmes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
