Global concern for the illicit transportation and trafficking of nuclear materials and other
radioactive sources is on the rise, with efficient and rapid security and non-proliferation …

A prototype of hybrid gamma imager has been developed, based on a single Timpex3
readout chip hybridized with a 1 mm thick cadmium telluride semiconductor. This prototype …

The system response of a gamma camera is dependent on the photon energy, thus the
energy-dependent response function needs to be considered to improve the quality and …

Here a novel, real-time, highly-compact imaging system capable of detecting and localising
gamma rays, thermal and fast neutrons is reported. The imaging system presented in this …

In the framework of a national funded program for nuclear safety, a first prototype of portable
gamma camera was built and tested. It integrates a Caliste-HD CdTe-hybrid detector …

Radiation mapping, through the detection of ionising gamma-ray emissions, is an important
technique used across the nuclear industry to characterise environments over a range of …

This work presents the application of a novel evolutional algorithmic approach to determine
and reconstruct the specific 3-dimensional source location of gamma-ray emissions within …

Radioactive sources exist in environments or contexts that influence how they are detected
and localised. For instance, the context of a moving source is different from a stationary …

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 …

The purpose of this study is to perform radiation monitoring by acquiring gamma images and
real-time optical images for 99m Tc vial source using charge couple device (CCD) cameras …
