This study is designed to examine the thermoluminescence characteristics of potassium fluoride for possible use as a thermoluminescence dosemeter. Thermoluminescence measurements were carried out at doses up to 20 Gy and heating rates between 0.2 and 4 °C/s. The glow curve of the fluoride, readout at 1°Cs⁻¹, exhibited two peaks at 130 and 250 °C. In addition, two shoulder peaks appeared at 70 and 200 °C. The kinetic parameters of the peaks were determined using glow curve deconvolution, peak shape and variable heating rate methods. The intensity of the 130 °C peak exhibited linearity at low doses and sublinearity at high doses. The dose response of the 250 °C peak is supralinear at low doses but becomes linear with further increase in dose. The intensity of 130 °C peak is affected by thermal quenching. Glow curve deconvolution indicated the presence of four peaks in the glow curve.

本研究旨在检查氟化钾的热致发光特性，以用作热致发光剂量计。在高达20 Gy的剂量和0.2至4°C / s的加热速率下进行热致发光测量。氟化物的辉光曲线，在1°C ^-1时读数，在130和250°C下显示两个峰。此外，在70和200°C下出现两个肩峰。使用辉光曲线解卷积，峰形和可变加热速率方法确定峰的动力学参数。130°C峰的强度在低剂量下显示线性，在高剂量下显示亚线性。250°C峰的剂量响应在低剂量时是超线性的，但随着剂量的进一步增加而变为线性。130°C峰的强度受热淬火的影响。辉光曲线解卷积表明辉光曲线中存在四个峰。
