During nuclear search operations, the localization of radioactive sources can be a time-consuming process that requires mapping relative radiation intensity in large area to determine position source. This article introduces use machine learning, specifically temporal convolutional network (TCN), estimate direction between detector array and static <sup xmlns:mml="http://www.w3.org/1998/Math/Ma...

Background: The natural radioactivity level and the radon concentration of soil were measured at four important geothermal area located in Dikili geothermal region, Turkey. Materials and Methods: The natural radionuclide content of soil samples were measured by NaI(Tl) gamma spectrometer system and the soil radon concentration were determined using Kodak-Pethe LR-115 Type II Solid State Nuclear...

A large number of the presently running neutrino and dark-matter experiments use thallium-doped cesium-iodide CsI[Tl] crystals, sodium-doped CsI[Na] or sodium-iodide NaI[Tl] crystals. In present paper we calculate elastic inelastic cross sections for neutral-current supernova-neutrino scattering off $^{127}\mathrm{I}$ $^{133}\mathrm{Cs}$, relevant using CsI[Tl], CsI[Na], We study also folded wi...

In this paper, we propose a CdZnTe rotating and spinning gamma camera attached with a slit collimator. This imaging system acquires convergent planar integrals of a radioactive distribution. Two analytical image reconstruction algorithms are proposed. Preliminary phantom studies show that our small CdZnTe camera with a slit collimator outperforms a larger NaI(Tl) camera with a pinhole collimato...

ANAIS (Annual Modulation with NaI’s) is an experiment planned to investigate seasonal modulation effects in the signal of galactic WIMPs using up to 107 kg of NaI(Tl) in the Canfranc Underground Laboratory (Spain). A prototype using one single crystal (10.7 kg) is being developed before the installation of the complete experiment; the first results presented here show an average background leve...

A fixed-point measurement of cosmic-ray intensity has being continued at Chiba, near Tokyo in Japan to obtain the time-sequential data. High efficiency neutron rem counter and Multi-sphere neutron Spectrometer (Bonner Sphere: BS) were used for the measurement of cosmic-ray neutron components and for the evaluation of the cosmic-ray ionizing components, NaI(Tl) scintillation spectrometer was emp...

Gamma-ray Localization Aided with Machine-learning (GLAM) utilizes an array of four rectangular NaI(Tl) detectors, and data processed a k-nearest neighbor machine learning model, to predict the location gamma-ray sources in stationary scenarios. This work demonstrates GLAM capabilities real source locations when trained purely on simulated data. To account for efficiency differences not capture...
