A fully automated and fast pneumatic transport system for short-time activation analysis was recently developed. It is suitable for small nuclear research reactors or laboratories that are using neutron generators and other neutron sources. It is equipped with a programmable logic controller, software package, and 12 devices to facilitate optimal analytical procedures. 550 ms were only necessar...

Introduction Neutron activation analysis (NAA) is a nuclear process used for determining the concentrations of elements in a vast amount of materials. NAA relies on excitation by neutrons so that the treated sample emits gamma-rays. It allows the precise identification and quantification of the elements, above all of the trace elements in the sample. NAA has applications in chemistry but also i...

Urban ares are subjected to intensive pollution due continuous anthropogenic activity. In order assess the influence of thermal power plants and waste incineration on City Moscow recreational areas, mass fractions 37 major trace elements were determined using instrumental neutron activation analysis in soil samples collected at two different depths vicinity more potential contamination sources....

Organohalogens, especially organochlorinated compounds (OCs) such as polychlorinated biphenyls (PCBs), have long been recognized as a potential threat to human health and, therefore, these compounds have been widely investigated in foods [3, 27], vegetation [9, 14], and the atmosphere [1, 11]. Recently, interest in using extractable organohalogens (EOX) as parameters for the quantification of t...

An analysis of neutron diffraction data of liquid deuterated terr-butanol at room temperature to determine its molecular conformation is presented. Being a big molecule of 15 sites, the analysis is tricky and needs careful consideration. The resulting molecular parameters are compared with those obtained from other experimental data analysis and model calculations. The information about the int...

As a continuation of diffraction work on melts from eutectic binary systems such as Al-Sn [1], Au-Co [2], and Bi-Cu [3] an investigation of melts from the eutectic system Sn-Zn by means of neutron diffraction will be described in the present work. The liquidus lines in the constitution diagrams of these systems always show a point of inflection, so th a t segregation tendency in molten state is...
