Abstract

Identification of elements is an important part of material science. Neutron activation is a technique to determine the individual signature of each element. The elements are placed in close proximity to a radioactive source so that they absorb radiation and become radioactive. Each element decays at a unique rate so that the amount of gamma radiation released on decay is a good measure for the identification of the element. For this study a range of elemental isotopes are tested in a particular energy band to provide accurate data for neutron decay. This is a valuable technique because it can be used on mixed materials to determine the component elements. The sensitivity, accuracy and non-destructive nature of the method makes it very adaptable to many areas of industry providing insights into wastes and other materials. Further advantages of neutron activation are the wide variety of materials that can be studied and the large number of elements it is possible to detect. This technique can be found in the fields of archaeology, biochemistry, environmental restoration and medicine.
