In this work, we evaluate the use of silicon photomultipliers (SiPMs) as a suitable candidate for use as a photodetector for thermoluminescence measurements. The measurements were based on the Hamamatsu S13360-series with a pixel area of 3 ? 3 mm2 and microcell pitches of 25 ?m, 50 ?m, and 75 ?m, which were mounted on a Ris? TL/OSL reader system with LiF:Mg,Cu,Si chosen as the reference TL material. Through the experiment, we showed that the typical TL glow curves can be obtained with SiPMs, despite their lower geometric efficiencies. We also demonstrated the dose response of SiPMs ranging from 6 to 66 mGy for three different photon threshold levels. The detection limit was approximately equal to 0.2 mSv, 0.08 mSv, and 0.17 mSv for 25 ?m, 50 ?m, and 75 ?m SiPMs, respectively. More importantly, a sensitivity change and sensor temperature depending on a TL reading up to 260 ?C was monitored on a sequential readout. Lastly, we discuss some of the possible benefits and limitations of SiPM-based TL measurements in comparison to PMT-based TL measurements.
