Sensitivity analysis of fluorescent nuclear track detectors for fast and high‐energy mono‐energetic neutron dosimetry
This study compares FNTD and PADC detector sensitivities, demonstrating a notable energy and converter thickness dependence for FNTDs, which is essential for precise dosimetry.

A benchmarked MC model for fast neutrons was then applied to analyze the FNTD signal for high-energy neutrons.
