“…The 90÷150 mm fraction was then etched in HF and washed in HCl [7]. The measurement sample comprised quartz inclusions with a size greater than 90 mm and a density between 2.63 and 2.67 g/cm3, separated using sodium poly tungstate [9,10]. The grains were preheated before ED measurements to eliminate the influence of unstable traps on luminescence counts.…”

The presented work was the first attempt to increase the accuracy of dating natural archeological monuments, namely, the Ballabur castle in Lenkaran of Azerbaijan Republic, by employing the Thermoluminescence (TL) dating method. Luminescence measurements were performed to find out the equivalent dose (ED). Registration of TL signal was carried out using the HarshowTLD 3500 Manual Reader. The irradiation was performed at an ambient temperature from a 60 Co source at different dose levels, and a dose rate of the 60 Co source was determined by EPR spectrometric method using an individually wrapped Alanine Dosimeter. Soil samples were collected close to the pottery sample to determine the natural dose rate. Uranium, Thorium, and Potassium concentrations in soil. The annual dose rate was obtained using a γ-spectrometer with a hyper-pure germanium detector, which was 2.98±0.19 mGy/year. the cosmic dose rate, which pertains to radiation from cosmic sources, was also calculated and found to be 0.10±0.01 Gy/ka. Online dose rate and age calculator calculated the sample's age as 920±50 years which is in line with the age of this area estimated by historians.

“…The brick sample underwent a series of steps, including crushing and sieving, to obtain grain size fractions of 80 to 120 µm. The targeted grain fraction was then treated with HCl, subjected to heavy liquid separation, and etched in 40% HF [9], [10]. Precipitated fluorides were subsequently dissolved using HCl.…”

The study aimed to improve the precision of dating historical landmarks, specifically the Ballabur castle in Lenkaran, Azerbaijan Republic, using the thermoluminescence dating (TL) method. The annual dose rate, calculated with a -spectrometer equipped with a hyper-pure germanium detector, was found to be 2.98±0.19 mGy/year. By employing an online dose rate and age calculator, the sample's age was determined to be 920±50 years, consistent with the historical estimates of this region.
