LURAD: Design Study of a Comprehensive Radiation Monitor Package for the Gateway and the Lunar Surface

Moon is an auspicious environment for the study of Galactic cosmic rays (GCR) and Solar Particle Events (SEP) due to the absence of magnetic field and atmosphere. The same characteristics raise the radiation risk for human presence in orbit around it …

Data Acquisition System of a Comprehensive Radiation Monitor for Lunar Mission

The data acquisition system of a radiation monitor package for lunar mission is presented. The package enables the measurement of the flux of all the main particles present in the lunar environment as a function of their energy, as well as the …

Spatial Localization of Radioactive Sources for Homeland Security

In general localization of radioactive sources or hotspots is a major issue for radiological safety of operators in nuclear facilities and in National Security. For this purpose, portable Gamma-Ray Imaging (GRI) systems allow remote localization of …

A machine learning approach in the estimation of a radioactive source position using a coded aperture device

Coded Aperture γ-cameras have been used for more than three decades for imaging radioactive source distributions encountered in astrophysics, in decommissioning of nuclear facilities, and in nuclear medicine. These devices enable the identification …

GEANT4 simulation study of the response of a miniature radiation detector in Galactic Cosmic Rays and inside a spacecraft.

The Miniaturized Detector for Application in Space (MIDAS) is a compact device with dimensions 5 x 5 x 1 cm 3 which combines position sensitive Si detectors and a fast neutrons spectrometer. MIDAS is developed with purpose to act as a linear energy …

Radioactive source localization using a data driven MVA method

We present a small form factor (0.5 cm3) static CdZnTe (CZT) sensor network consisted of a number of Non Directional Detectors (NDD) capable to localize a stationary radiation source in 3D. The localization is performed with fusion algorithms based …
