Summary of Experience

  • Application of Radiotracer techniques in Hot Atom Chemistry, gamma radiation effects on solids.
  • Original technique for measuring total body chlorine to determine extra-cellular water, in vivo, using prompt gamma neutron activation analysis.
  • Design and calibration of a very low radiation dose facility for measuring in vivo, carbon, nitrogen and oxygen and hence protein, fat and water simultaneously in young experimental animals such as sheep or pigs. Inelastic neutron scattering reactions on C, N and O were employed and nano-second timing techniques were applied using a compact sealed tube 14 MeV neutron generator and the associated particle technique.
  • Field deployable instrumentation for terrestrial carbon sequestration studies: in situ analysis of carbon and water content of soil using pulsed 14 MeV neutrons; compact digital signal processing for gamma spectroscopy.
  • Fast neutron detection in mixed neutron-gamma fields.

Projects as Principal Investigator

  • Department of Defense (Strategic Environmental Research and Development Program, www.serdp-estcp.org), March 2010, "Identification of UXO using the Associated Particle Neutron Time-of-Flight Technique".

One of the major problems facing the DoD is dealing with unearthed UXO (UneXploded Ordnance) items at past or present military facilities or munition testing grounds. Range clearance operations must distinguish UXO filled with High Explosives (HE) from inert ordnance. Handling every piece of ordnance as "live" increases disposal and remediation costs to the DoD. The suitability of the Associated Particle neutron Time-of-Flight technique(APnTOF) to non-destructively identify previously found UXO as hazardous or benign will be demonstrated in this project. This technique uses an electronically collimated tagged neutron beam from a novel compact, portable field deployable 14 MeV neutron-generator system to simultaneously provide 3-D imaging of objects and their elemental composition.

This system is modified easily for applications in homeland security, non-proliferation and carbon sequestration.
