Ceramic thermoluminescence detectors (TLDs) are low-cost devices with high spatial resolutionand very easy to use. The basic characteristics of alumina-based ceramic TLDs (Chiba CeramicMfg. Co., Ltd. A8) in response to X-ray and charged particle beams (H, He, C, Ne, Ar) have beenreported in an effort to apply TLDs as a QA/QC tool for charged particle therapy. The glow curvehas two peaks, and the main peak is located at 148 °C and 694 nm. For each irradiation, fourdose levels were given: 0.5, 1.0, 2.0, and 5.0 Gy in water. The main peak showed good linearityand repeatability for X-rays. However, thermoluminescence efficiency decreased slightly withincreasing irradiation dose with charged particle irradiation. The thermoluminescence efficiencyof the main peak showed a very small dependence on linear energy transfer (LET) compared withcommon TLDs. This ceramic TLD may be applicable as a verification tool in a limited LET rangesuch as proton therapy.
