“…It is well known that the thermal quenching effect is dominant around the TL dosimetric peak of CaF 2 :Mn [27,28]. Therefore, the reduction of E a values was clearly observed by previous researches in this field [29,30].…”

A high temperature ratio (HTR) method has been proposed to correct the linear energy transfer (LET) dependence of thermoluminescent (TL) efficiency. To realize the use of the slab-type thermoluminescence detector (TLD) that based on the phosphor Li 3 B 7 O 12 :Cu for heavy charged particle beam, the HTR method has been considered. To improve the reproducibility of HTR, the slow heating rate method is introduced in this report and the coefficient variations of HTR decreased from 10%-20% to 8%. The relation between TL-efficiency, HTR, and LET for Li 3 B 7 O 12 :Cu was manifested and the TL-efficiency as a function of HTR was derived in an attempt to measure the absorbed dose without LET information. The feasibility of the HTR method in therapeutic carbon beams was evaluated by comparing the dose estimated by Li 3 B 7 O 12 :Cu and by an ionization chamber. The accuracy of dose estimation in carbon beams was improved by using the HTR method, but there is room for further improvement. The use of Li 3 B 7 O 12 :Cu in heavy charged particle beams can be materialized with further improvement of HTR sensitivity.

“…Thermal quenching effect can be another reason for this reduction, as efficiency increases as temperature increases. [ 29 ] In the measurement cycle (reproducibility) experiment, the stability of the TL glow curve of the sample was investigated. For a good dosimeter, each measurement cycle needs to give the same result.…”

This marble extracted from deposits in Elazığ in Turkey resembles red meat in appearance and is only found in Elazığ. This type of marble has been widely used in the most famous architectural structures and buildings. In this study, the thermoluminescence (TL) properties of a unique marble that originated from Turkey, named Rosso Levanto, were investigated. Two distinct TL peaks were observed at 160°C and around 375°C. Particle size experiments showed that best TL intensity was seen at 200 μm particle size and therefore dose–response, heating rate, cycle of measurement and fading experiments were carried out on powdered samples with a particle size of 200 μm. The findings revealed good linearity in dose–response, observed up to 0.5 kGy. The reproducibility experiment gave good results, but peak intensity decreased by about 40% in first 6 h of storage in a dark room.
