The thermally stimulated processes in NaF X‐irradiated at room temperature are studied. Three processes are observed whose relative weight depends on the F‐coloring stage: (1) electron release; this causes glow peaks to appear at 75 and 115°C, as a result, M+ centers are annealed out; (2) interstitial fluorine release from different traps and subsequent recombination with F‐centers and F‐aggregate centers, it causes glow peaks at 70, 130, 200, 240, and 280°C; (3) F‐center migration causing their annealing by recombination with interstitials or the formation of F‐aggregate centers.

“…The development of NaF based TLDs is challenging due to a complex manner of its TL properties influenced by factors like type and energy of ionizing radiation, thermal and radiation dosage history, etc. [1][2][3][13][14][15][16][17]. Both LiF and NaF like many others have drawback consisted in a low sensitivity to low doses and an early saturation at higher doses.…”

Abstract. The thermally stimulated luminescence (TSL) and exoemission (TSE) in Li and Cu doped NaF and LiF single crystals irradiated with electron high energy electron beams of (10 MeV, doses 0.75 and 2 MGy) have been investigated. The results obtained reveal important properties that suggest that the crystals have a sufficient radiation stability and sensitivity for high energy electron beams and are promising for application as high-dose detectors of electron radiation.

Thermoluminescence of NaF harshaw single crystals irradiated to very low and high doses

NaF Harshaw single crystals are found to show very little thermoluminescence. The thermoluminescence response, however, can be increased by a process called radiation induced sensitization. The sensitized samples when γ‐irradiated to a dose less than 1 × 103 R exhibit only one glow peak at 306°C. This peak is tentatively related to impurity‐vacancy dipoles. On being exposed to 1 × 107 R dose, the samples show two peaks at 140 and 254°C, respectively. Phototransfer and optical bleaching experiments are performed to find the relationship between these two peaks and the colour centres. It is concluded that both the peaks are due to the thermal destruction of P‐centres.
