Special Issue Information

Dear Colleagues,

Applications of analytical methods using fast neutrons can be found in almost every conceivable field of scientific inquiry. While it is correctly identified as a method of “chemical analysis” because of the information it can generate, it is based on nuclear rather than atomic or molecular properties. Neutrons can be obtained by several nuclear reactions, the best known is d+t →α+n reaction producing the beam of 14 MeV neutrons. Simplicity of design and inherent safety of operation makes the use of neutron generators very attractive. The 14 MeV neutrons have recently been again in the spot mainly because of the development of smart analytical instrumentation for explosive and drugs detection. Oil industry has recognized advantage provided by the use of neutron probes some time ago and 14 MeV neutrons are widely used in well-lodging activities.

Recent advances in technology of neutron generator fabrication has led to extension of instrument lifetime and improved reliability of operation. Reduction in size made online analysers very popular especially in coal and cement industry for monitoring the composition of the raw material on the conveyor belts. Homeland security in today’s world depends on our ability to monitor borders for the potential trafficking of explosives, special nuclear material, drugs and chemicals. The container inspection systems are using penetrating radiations in the scanning geometry, with the detection of transmitted or radiation produced in investigated object. Tagged neutron beams have been used for the inspection of shipping container for the presence of the threat materials hidden within cargo.

We invite contributions in the form of expert comprehensive reviews or research articles dealing with applications, new instrumentation developments, other uses of fast neutrons from a wide perspective.

Contributions are expected to address, but are not limited to, the following issues:

  • New developments in Accelerator Technology
  • Collimated Neutron Beams, Slow and Fast
  • Instrumentation for Biological and Medical Applications
  • Nuclear Well Logging
  • Underwater Surveillance System for the Inspection of Strategic Coastal Installations
  • Neutron Generators in Extreme Conditions
  • Use of Tagged Neutron Beam for Sea Container Inspection
  • Radiological Risks from Irradiation of Food in Neutron Inspection Systems
  • Detection of Special Nuclear and Other Threat Material
  • Carbon in Soil
  • Diamond Detection in Kimberlite
  • Process Control of Industrial Production Processes
  • QA/QC Measures, Reference Materials, Standards and Simulants

The results of testing a prototype of a separator for detecting diamonds in kimberlite ore using tagged neutron method are discussed. Kimberlite ore was irradiated with fast tagged neutrons with an energy of 14.1 MeV. The elemental content of the tray with kimberlite ore was determined. The criterion for detecting diamond was the presence of excess carbon concentration in a certain region of a kimberlite sample. Full article
