Localization and identification of radioactive sources is a key issue for operators in nuclear facilities and homeland security. We propose a γ-ray detection system without moving parts, based on a scintillator crystal read out by an array of silicon …
We address on-scene nuclear forensics with a portable NaI 3 inch detector by training a convolutional neural network on spectra synthesized from Geant4 event level pools with bootstrap resampling, mixed with measured background, and regularized via …
Gamma-ray spectroscopy is an essential technique for identifying the composition of radioactive materials. This work presents a detailed algorithm for analysing gamma-ray spectra, focusing on peak detection, energy calibration, efficiency calibration …
