Abstract: The quartz samples with different thickness were adopted to study the thermoluminescence (TL) responses to the α-irradiation. The quartz was exposed at 2.64 Gy α-irradiation dose, and then the exposed quartz was installed on aluminous slice with different thickness and same area. According to area integral of the TL peak measured on the equipment, the responses to the alpha dose were obtained for the different thickness quartz samples.
