Fast neutron radiography scanner for the detection of contraband in air cargo containers.

There is a growing need to rapidly scan bulk air cargo for contraband such as illicit drugs and explosives. The Commonwealth Science and Industrial Research Organisation (CSIRO) have been working with Australian Customs Service to develop a scanner capable of directly scanning airfreight containers in 1--2 minutes without unpacking. The scanner combines fast neutron and gamma-ray radiography to provide high-resolution images that include information on material composition. A full-scale prototype scanner has been successfully tested in the laboratory and a commercial-scale scanner is due to be installed at Brisbane airport in 2005.

Feasibility study for a low-cost 3D gamma-ray camera.

A novel gamma-ray camera is proposed based on Positron Annihilation Compton Scattering Imaging (PACSI). The camera comprises a positron source and a fast, position-sensitive gamma-ray detector. Monte Carlo simulations of the camera have demonstrated that it should be capable of forming 3-D images of objects that can only be viewed from one side. A simple 1-D PACSI camera has been constructed and tested in the laboratory. Prospects for the construction of a full 3-D prototype camera are discussed.

An on-belt elemental analyser for the cement industry.

On-line control of raw mill feed composition is a key factor in the improved control of cement plants. A new and improved on-conveyor belt elemental analyser for cement raw mill feed based on neutron inelastic scatter and capture techniques has been developed and tested successfully in Adelaide Brighton's Birkenhead cement plant on highly segregated material with a depth range of 100 to 180 mm. Dynamic tests in the plant have shown analyser RMS total errors of 0.49, 0.52, 0.38 and 0.23 wt% (on a loss free basis) for CaO, SiO2, Al2O3 and Fe2O3 respectively, when 10-minute counting periods are used.
