摘要： A scintillator receives radiation and produces light. The scintillator is composed of columnar crystals arranged upright. Conical end portions of the columnar crystals are embedded in a resin layer formed on a light detection section. The resin layer, made from a thermosetting resin material, is heated and cured with the end portions embedded therein. Because a refractive index of the resin layer is lower than that of the columnar crystals, average refractive indices of respective layers between the columnar crystals and the light detection section change continuously. The resin layer prevents the end portions from damage and improves efficiency of incidence on the light detection section.

摘要： In a radiation detector, a scintillator converts radiations penetrating through a sensor panel to light, and the light is detected by a photosensor in the sensor panel. A reflector layer including a specular reflection and retro-reflection layers is provided on the opposite side of the scintillator to the sensor panel. The specular reflection layer specularly reflects short-wavelength components of the light from the scintillator, and lets long-wavelength components of the light pass through it. The photosensor can detect the short-wavelength components efficiently at positions close to their origins because they are guided along columnar crystals of the scintillator. Since long-wavelength components are less refrangible and tend to deviate from their origins, causing crosstalk, the retro-reflection layer retroreflects the long-wavelength components toward the sensor panel, so that the long-wavelength components also reach the sensor panel at positions close to their origins.
摘要翻译：在辐射检测器中，闪烁器将穿过传感器面板的辐射转换成光，并且光由传感器面板中的光电传感器检测。包括镜面反射层和反射反射层的反射层在闪烁体的相对侧设置到传感器面板。镜面反射层镜面反射来自闪烁体的光的短波长分量，并使光的长波长分量通过它。光电传感器可以在靠近其起源的位置有效地检测短波长分量，因为它们沿闪烁体的柱状晶体引导。由于长波长分量不太可重复，并且倾向于偏离其起源，引起串扰，所以后向反射层将长波长分量向后传输到传感器面板，使得长波长分量也在靠近的位置到达传感器面板到他们的起源。
