State–of–the–art hybrid semiconductor pixel detectors such as Medipix2 are suitable for energy– and position–sensitive nuclear spectroscopy. In addition to excellent energy– and spatial–resolution, these devices can operate in spectroscopic, single–quantum counting and/or on–line tracking mode. A devoted compact USB–readout interface provides functionality and ease of operation. The compact and versatile Medipix2/USB radiation camera provides visualization, vacuum and room–temperature operation as a real–time portable active nuclear emulsion.
