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 …

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 …

An AI Approach in Radioactive Source Localization by a Network of Small Form Factor CZT Sensors

We present a small form factor (0.5𝑐𝑚3) static CZT sensor net-work consisted of a number of Non- Directional Detectors (NDD)capable to localize a stationary radiation source in 3D. The localiza-tion is performed with a fusion algorithm based on AI …

Localization of radioactive source using a network of small form factor CZT sensors

We present a small factor (0.5 cm3) CZT static sensor network consisted of a number of Non-Directional Detectors (NDD) capable to localize bare and lightly shielded radiation sources. The localization is performed with a fusion algorithm based on a …
