This study assesses radiation doses from the CT component of SPECT/CT scans used in lymphoscintigraphy procedures at a single institution. Data from 130 patients were analyzed, focusing on CT dose metrics, including CTDIvol, SSDE, and DLP, alongside technical parameters such as tube current, collimation, and pitch. Results showed an average CTDIvol of 2.07 ± 1.25 mGy (range:... -

The study of Urartian metallurgy remains a significant topic in the investigation of metal production in the Ancient Near East during the first half of the first millennium BC. Excavations conducted between 2014 and 2016 at the newly discovered necropolis of Teishebaini (Karmir Blur), a city of the Kingdom of Urartu, uncovered over 250 burials, yielding several hundred metal artefacts. The...

Antimony-124 (¹²⁴Sb) is a promising radionuclide for medical applications, particularly in low-dose rate intravascular brachytherapy (IVBT), due to its unique nuclear characteristics. High-energy β-particles (1-2 MeV and higher) are effective for local tumor or restenosis treatment. Low-energy γ-rays (20–300 keV) are suitable for imaging, dosimetry, and monitoring the treatment process without...

Isotopes research and production department at A. Alikhanyan National Science Laboratory (AANL) develops production technologies for Ga, Cu, and Tc radiometals for medical applications [1-4]. The technology is based on solid target irradiation under an 18 MeV proton beam of an IBA C18 cyclotron. The solid target production method leads to higher activity of the final product than the liquid...

Ionizing radiation (X-rays, proton beams) causes structural changes in materials. If a vibrating metallic wire is subjected to such radiation, the natural frequency of the wire is affected as a result of changes in the elastic characteristics of the material. This paper presents the results of experiments on the impact of X-ray radiation in the range of 100-165 keV and a proton beam with...
