Specialists from Armenia’s Nuclear and Radiation Safety Center (NRSC) participated in the Nuclear Forensics Technical Exchange, held on August 20–22 at Argonne National Laboratory, in Lemont, (Illinois, the US). The international event brought together experts to discuss radioactive source registries, field data collection, and the development of National Nuclear Forensics Libraries (NNFLs). Armenia was represented by Ms. Arpi Khachatryan, Mr. Karen Haroyan, and Ms. Anahit Petoyan. During the program, Ms. Petoyan, a PhD student at NRSC, delivered a presentation titled “Towards Accurate Quantification of Non-Homogeneous Swipe Samples in Gamma Spectrometry.” Her research addressed challenges in analyzing heterogeneous contamination and proposed methods to improve measurement accuracy in nuclear forensics investigations. The program combined theoretical discussions—such as the expansion of the xARIS platform developed by NRSC and the outcomes of the ISTC cooperation project—with hands-on sessions using Argonne’s NNFL toolkit, field detection instruments, and integrated registry software. Such exchange of experience is an important step in developing nuclear forensics capabilities in Armenia, contributing to the creation of a National Nuclear Forensic Library.
