Description
Solid-State Nuclear Track Detectors (SSNTDs) have been studied since the 1950s and have proven highly effective for detecting neutrons and ionizing particles. Their key advantages include compact design, high detection efficiency, no need for electronic components, simple operation, and the ability to detect neutrons even at low fast-neutron fluences. In 2023, the STU laboratory acquired the TASLImage™ system for radon and neutron dosimetry using SSNTDs, successfully integrating it into its research portfolio. This presentation provides a brief overview of the fundamental principles of SSNTDs and highlights a series of experiments aimed at deepening our understanding of detector behavior under varying conditions, such as different neutron spectra, etching techniques, scanning configurations, degrader use, improper handling, and ageing and fading effects. Beyond controlled experiments, SSNTDs have been creatively applied in diverse contexts: measuring radon levels in caves and residential buildings, assessing doses from neutron isotope sources, performing neutron imaging, mapping angular distributions around deuterium-deuterium (DD) neutron sources, and applying advanced data analysis techniques, including Principal Component Analysis, Machine Learning, and Artificial Intelligence, done within the EU-funded PANDORA project. The results demonstrate the STU team's growing expertise in SSNTD technology, which holds promise for future applications in neutron and alpha dosimetry across Slovakia.
