The response of a thermoluminescent dosimeter to low energy protons in therange 30-100 keV

This study demonstrates the thermoluminescence (TL) response of CaF2:Tm (co mmercial name TLD-300) to 30-100 keV protons which were generated by means of a Cockcroft-Walton accelerator. The phenomenon in which the total thermo luminescent output from CaF2: Tm (TLD-300) decreases with proton energy fro m 30 to 100 keV (with increase of LET) can be interpreted by the track stru cture theory (TST). The analysis of the glow peaks: P2 (131 degreesC), P3 ( 153.5 degreesC) and P6 (259 degreesC), of TLD-300 show the oscillatory decr easing phenomenon as a function of incident proton energy, which can be int erpreted with the TST and the oscillatory emission of electrons in a thermo luminescent dosimeter (TLD) that is caused by resonant or quasi-resonant ch arge transfer in ion-atom interactions in this TLD-300.
