The results of more than 280 different experiments aimed at exploring the main features and performances of a newly developed gamma imager, called iPIX, are summarized in this paper. iPIX is designed to quickly localize radioactive sources while estimating the ambient dose equivalent rate at the measurement point.

A panoramic coded aperture gamma camera for radioactive hotspots localization
/ Paradiso, V (Mirion Tech., France ; CERN) ; Amgarou, K (CEA Marcoule, Bagnols-sur-Cèze) ; Lanaute, N Blanc De (Mirion Tech., France) ; Schoepff, V (LIST, Saclay) ; Amoyal, G (LIST, Saclay) ; Mahe, C (CEA Marcoule, Bagnols-sur-Cèze) ; Beltramello, O (CERN) ; Liénard, E (Caen U.)
A known disadvantage of the coded aperture imaging approach is its limited field-of-view (FOV), which often results insufficient when analysing complex dismantling scenes such as post-accidental scenarios, where multiple measurements are needed to fully characterize the scene. In order to overcome this limitation, a panoramic coded aperture γ-camera prototype has been developed. [...]

3-D localization of radioactive hotspots via portable gamma cameras
/ Paradiso, V (Mirion Tech., France ; CERN) ; Amgarou, K (CEA Marcoule, Bagnols-sur-Cèze) ; Blanc de Lanaute, N (Mirion Tech., France) ; Bonnet, F (Mirion Tech., France) ; Beltramello, O (CERN) ; Liénard, E (Caen U.)
A portable stereo gamma camera has been built, based on two hybrid pixelated detectors, each of them comprising a 1 mm thick CdTe substrate bump-bonded to the Timepix readout chip, a pixelated CMOS ASIC consisting of 256 × 256 pixels with 55 µm pitch.
The technique described in this paper allows the automatic estimation of the distances between the prototype and the located radioactive sources by using triangulation based on epipolar geometry. The 3-D Cartesian coordinates of the sources are provided even when they are hidden behind an occluding material, such as a wall, or inside a barrel. [...]
