Application of Neutron-capture to Elemental Analysis

To many in our community the study of nuclear Physics is a mental exercise that strengthens the mind, and helps to accumulate the appropriate number of points for a BSc degree. In reality many of the fundamental concepts of Physics, and nuclear physics in particular, have led to significant improvements in the community. (ref. MRI, CAT, PET, radiation therapy, nuclear power). This paper addresses the use of neutron capture in the identification of elements in small amounts. Applications have significant import in environmental areas (ref. heavy metal detection, Ni-Cd battery recycling) and community health (ref. Drug detection). Here we address the problems of nitrogen detection in medical applications (protein measurement) and explosives detection (parcel bombs and landmines)
