Investigation of emission spectra, dose response and stability of luminescence from NaCl

► A 590 nm/260 °C TL peak was found in many commercial salts (NaCl). ► Salt has no significant pre-existing 590 nm/260 °C TL. ► This TL peak is dose-dependent and stable over 2 months (minimum). ► Unless light-exposed, NaCl is suitable as an opportunistic retrospective dosimeter.
