Fusion Based Neutron Sources for Security Applications: Neutron Techniques [PDF]

open access: yes, 2014
The current reliance on X-Rays and intelligence for na- tional security is insufficient to combat the current risks of smuggling and terrorism seen on an international level. There are a range of neutron based security techniques which have the potential

Neutron activation analysis of multimetallic accumulation in dolomites [PDF]

open access: yesHemijska Industrija, 2008
The reason for exploring polymetallic ores, which are found in dolomite structures of the Veovača and Borovica zone near Vareš, lies in the fact that there is very little information about its chemical structure.

Neutron spectrum determination of p+Be reaction for 30 MeV protons using the multi-foil activation technique [PDF]

open access: yesEPJ Web of Conferences, 2020
At the NPI in Rez, the p + Be source reaction was investigated for 30 MeV proton beam and thick beryllium target. For neutron field determination of the p(30)+Be source reaction in close source-to-sample distance, the multi-foil activation technique with

Use of Instrumental Neutron Activation Analysis to investigate the distribution of trace elements among subsamples of solid materials [PDF]

open access: yes, 2014
The results of analytical measurements performed with solid-sampling techniques are affected by the distribution of the analytes within the matrix. The effect becomes significant in the case of determination of trace elements in small subsamples.
