The goal of this work was to evaluate the thermoluminescence features of Himalayan salt (HS) for the purpose of radiation dosimetry. As a result of its low cost, widespread availability in the market, and similarity to the tissues found in the human body. Irradiation of the samples was performed with a radiation source that utilised 137Cs. With a heating rate of 15 degrees Celsius per second and a final temperature of 320 degrees Celsius, the samples were subjected to TL analysis with the help of the Harshaw Model 2000B/C TLD Reader. In commercial salt samples, the glow curve (gwc) reveals the presence of a strong glow peak at temperatures ranging from 204 to 282 degrees Celsius. For the salt sample, the grain size (gz) is exactly proportional to the total light intensity (TL) of the glow curve shown in the graph. Not only that, but the findings also demonstrate that the TL intensity of the HS has a linear relationship with dosage throughout a wide range, spanning from 250 mGy to 20 Gy. The post- irradiated fading rate are investigated and shows the rate of thermal fading of HS, found to be equal 32% at storage time for 24 days. These results indicate that this material is very interesting for useful for TL-dosimetric applications.

“…[ 29 ] Gonzales‐Lorenzo et al studied the effect of annealing temperature on the structural, optical properties of a thermally treated naturally occurring salt from Lluta and the use of natural mineral as a retrospective TL dosimeter. [ 30 ] Toktamis et al used the rock‐salt crystals extracted from the Meke volcanic crater lake Konya, Turkey, to investigate the TL dosimetric properties. Machine learning techniques such as support vector machine (SVM), artificial neural network (ANN), and K‐nearest neighbor (K‐NN) were used to categorize the TL characteristics.…”

Dosimetric properties of thermoluminescent NaCl pellets from Khewra Salt Mines, Pakistan

Thermoluminescence (TL) and extended dosimetric characteristics of naturally occurring sodium chloride (NaCl) salt were studied. Pellets were prepared from mined crystalline salt obtained from Khewra Salt Mines, Pakistan and irradiated from 1 mGy to 10,000 mGy using cobalt-60 gamma source. The TL response showed two dominant peaks around 125 C and 230 C, respectively, at low doses, with an additional peak in between at doses beyond 300 mGy. A linear and supra-linear TL response was observed between 1 mGy-100 mGy and 100 mGy-10 Gy dose ranges, respectively.During the first 24 h post-irradiation, the TL intensity dropped by 20%. A maximum angular dependence of up to 50% was observed between 0 to 360 . For photon
