Luminescence studies focusing on sodium chloride crystals have been conducted in various parts of the world, including Brazil, India, Greece, Türkiye, Australia, Spain, and Poland. This material shows great promise in the field of dosimetry, as it has demonstrated high sensitivity, excellent reproducibility, a linear response, and a low minimum detectable dose. Moreover, it holds significant potential for applications in accidental dosimetry, providing valuable results for dating and retrospective dosimetry purposes. Natural sodium chloride encompasses different types of salts, such as Himalayan black salt, pink salt, and sea salt. The presence of these salt variations is attributed to their composition, which includes not only pure sodium chloride but also other elements like magnesium, potassium, sulfur, and calcium. These additional elements contribute to the unique characteristics and properties exhibited by these types of salts. A comprehensive study was conducted to investigate the effects of thermal treatments on pink salt crystals, aiming to enhance their luminescent intensity and thereby improve their sensibility to detect ionizing radiation. By subjecting the crystals to various thermal treatments, we observed significant changes in their luminescent signals. Firstly, we observed a change in the shape of the Thermoluminescence (TL) curve, indicating modifications in the properties of the luminescent F-centers present in the crystals. Additionally, we noticed a significant increase in the Optically Stimulated Luminescence (OSL) signal, indicating a greater ability of the crystals to store and release energy under optical stimulation. A particularly interesting discovery was the reduction in intensity of the third component of the OSL signal in darker-toned crystals. Also the spontaneous regeneration reported by other researchers was almost eliminated. Furthermore, our results demonstrated only a 2.5% fluctuation in experimental repeatability, indicating high consistency and reliability of the obtained data.
