| 内容記述 | The thermoluminescence of the ceramic material appears to be the result of damage to the crystal lattice by the radiation coming from the radioactive elements contained in the material. When the ceramic materials are heated up to the temperature of 400 or 500゜C, trapping electrons are ejected from their traps and fall back to their ground states with emission of light. The amount of light is a function of the dose and the light efficiency of the sample. The dose is proportional to the number of years that have elapsed since the ceramic material was treated by the last heating and to the natural rate of alpha particle radiation. In practice, the thermoluminescence glow curve of the sample to be dated can be measured quantitatively with a photomultiplier tube. The temperature of the hot-plate on which the sample is spread, and the output of the tube are recorded simultaneously. The sections of the equipment is shown in the block diagram (Fig.1). Thermoluminescence glow curve of the pottery sample in its natural condition can be satisfactorily recorded by this equipment. When the sample is subjected to an artificial radiation of γ-ray in cobalt, its glow-p eak heights in the series of our experiments are proportional to various dose. As the result, the relative equivalent radiation dose can be acquired by using the calibration curve. But the glow curve of the natural ancient ceramic materials are decayed in normal temperature. If the estimate of decay can be properly done and the radioactivity of the sample be measured by an alpha counter, the thermoluminescence method, mentioned above, may be an effective method for the ancient ceramic material's dating. | |||||||
