This paper presents a simulation of the spectroscopic performance of two large CZT coplanar detectors, 1.5 1.5 cm area and 1.0 cm thick, with coplanar anodes. A code, based on the GEANT libraries and classical Monte Carlo sampling, was developed to simulate experimental scenarios. This code adapts the GEANT capabilities for simulating complex detection systems for spectroscopic studies. Detecto...

AIMS To study the prognostic value of rapid-acquisition adenosine stress-rest myocardial perfusion scintigraphy (MPS) on a gamma camera using multipinhole collimation and cadmium-zinc-telluride (CZT) detectors. The secondary aim was to assess the diagnostic accuracy of the technique compared with invasive coronary angiography. METHODS AND RESULTS Retrospective analysis of 1109 consecutive pat...

Because of its excellent opto-electronic properties, CdZnTe (CZT) has been the material choice for x- and gamma-ray detectors operable at room temperature. CZT is leading commercially available room-temperature radiation detector today. Although much progress made over past three decades, today's crystals still face certain challenges, especially presence performance-limiting materials defects ...

The performance of the Radionuclide Aerosol Sampler/Analyzer (RASA) under high-activity conditions has been evaluated to maintain and protect operations International Monitoring System (IMS) radionuclide stations. Station measurements following Fukushima Daichi accident 11 March 2011 have combined with laboratory understand how quality made using RASA High-Purity Germanium (HPGe) gamma-spectrom...
