摘要： A multielement radiation detector in which many elements are arranged in array. Each element includes a scintillator which is tilted with respect to the incident direction of radiant rays, and a silicon photodiode which is opposed to the plane of incidence of the scintillator. The light-receiving plane of the silicon photodiode is tilted to meet the inclination of the scintillator. Therefore, the gradient of detection sensitivity distribution is reduced in the thickness direction of the detectors.

摘要： In a radiation detector having a radiation-stimulated light emitting scintillator and a photodetector for receiving the light emission from the scintillator, the scintillator is formed of a layer of phosphor particles and a light scattering layer is provided in an optical path between the phosphor particle layer and the photodetector. Light generated in the surface of the scintillator is scattered and absorbed by the light scattering layer in some degree so that the reduced quantity of light incident upon the photodetector lowers the output of the photodetector. This effect is balanced with the lowering of the photodetector output due to the absorption and scattering of light generated at the inner parts of the scintillator and further removes anisotropic light emission. As a result, signal-to-noise ratio is greatly improved.A shielding layer between the scintillator and photodetector prevents secondary radiation such as scattered and fluorescent radiation from reaching the photodetector. The shielding layer can also serve as the scattering layer.
摘要翻译：在具有辐射激发的发光闪烁体的辐射检测器和用于接收来自闪烁体的发光的光检测器中，闪烁体由荧光体颗粒层形成，并且光散射层设置在荧光体颗粒层和光电检测器。在闪烁器表面产生的光在一定程度上被光散射层散射和吸收，使得入射到光电检测器上的光的减少使得光电检测器的输出降低。由于在闪烁器的内部部分产生的光的吸收和散射，光电检测器输出的降低会使这种效果平衡，并进一步消除各向异性发光。结果，信噪比大大提高。闪烁体和光电检测器之间的屏蔽层防止二次辐射如散射和荧光辐射到达光电探测器。屏蔽层也可以用作散射层。
