The aim of this study is to propose and evaluate a low cost alternative solution as a detector module in nuclear imaging. For this purpose, we have assessed the performance of Gd2O2S:Pr powder scintillator in the form of thick screens easily produced in our laboratory. All measurements were carried out in photon counting mode using m99Tc. To our knowledge, Gd2O2S:Pr powder phosphor screens have never...
One way of smuggling drugs into a country is via the postal and courier services. Automated systems are necessary to scan incoming parcels and make quick decisions on whether they contain drugs or not. Few false positive and negative results are an important requirement for the end users of such a system, as neither parcels containing drugs should be lost nor parcels without drugs should stop the...
A system for drug detection using X-ray diffraction is currently being developed by the DILAX collaboration. A simulation program for modelling the response of an energy-dispersive X-ray diffraction system has been developed, with the two-fold aim of selecting possible configurations prior to experimental tests and of generating data for statistical models for prediction of drug content. Simulated...
