FNTD radiation dosimetry system enhanced with dual-color wide-field imaging (original) (raw)

This study presents an advanced radiation dosimetry system utilizing Fluorescent Nuclear Track Detectors (FNTDs) enhanced by dual-color wide-field imaging. The novel method incorporates confocal laser scanning fluorescent imaging combined with dual-color imaging to achieve automatic sensitivity calibration for each FNTD. The research demonstrates that this technique effectively mitigates the challenges posed by track overlap at high doses, allowing for improved estimation of detector sensitivity in environments with mixed neutron and photon radiation.
