Applications in Security and Environmental Imaging

Invited Paper

The importance of advanced imaging modalities in modern medicine is widely appreciated. Probably less familiar is their potential use for studying engineering processes in industry. This is especially true of techniques based on the use of high energy photons which can penetrate metal casings. Transmission imaging can distinguish individual phases in multi-phase flow, while the use of...

Applications in Security and Environmental Imaging

Oral Paper

Current research in the Nuclear Instrumentation group of the University of Liverpool focuses on the optimisation of the gamma ray Compton camera [1]. Such an imaging system can utilise two energy and position sensitive semiconductor detectors with the Compton scattering formula to gain position and energy information of gamma-ray emitting radioactive sources. This presents a significant...

93. Adaptive response matrices for optimised mixed-field imaging

Applications in Security and Environmental Imaging

Oral Paper

Pinpointing the location of radiological materials has the potential to be extremely useful in many scenarios, not least of which is in nuclear decommissioning. This subject forming the focus application of this research. We present a compact and lightweight mixed-field imaging system able to produce images of radiation source terms distributed in a local environment, passively and in near...

127. Digital fast neutron radiography of rebar in concrete

Applications in Security and Environmental Imaging

Oral Paper

Neutron imaging has previously been used in order to test for cracks, degradation and water content in concrete. However, these techniques often fall short of alternative non-destructive testing methods, such asgamma-ray and X-ray imaging, in terms of resolution. Further, they can be compromised by the significant expense associated with thermal neutron sources that can often precipitate the...
