    Abstract: A scintillator unit with less light leakage from a scintillator to an adhesive layer and a radiation detector that can improve sensitivity to radiation and the resolution of an image to be formed. Specifically disclosed is a scintillator unit including an adhesive layer between a scintillator and a supporting member and a low-refractive-index layer with a lower refractive index than the adhesive layer between the scintillator and the adhesive layer.

    Abstract: A method of producing a ceramic manufactured object including (i) a step of leveling a ceramic powder to form a powder layer, (ii) a step of irradiating the powder layer with a laser beam based on three-dimensional data to crystallize an irradiated site, and (iii) performing the steps (i) and (ii) in repetition, wherein in the step (ii), a surface of the powder layer is irradiated with the laser beam in an unfocused state.

    Abstract: In a related-art composite scintillator in which pores in a porous scintillator are filled with an absorbing member or the like, as the ratio between the structural period of the composite and the thickness in an optical waveguide direction becomes smaller, almost all light is absorbed, and, in some cases, it is difficult to obtain a sufficient light amount for forming an adequate image. Provided is a scintillator including multiple first phases having directionality in a direction connecting two surfaces thereof which are not located on a same surface and a second phase positioned around the first phases, in which each of the multiple first phases is in the shape of a column, and an absorbing portion is provided in part of one of the two kinds of phases, which has a lower refractive index.

    Abstract: In a scintillator used for radiation detection, such as an X-ray CT scanner, a scintillation crystal body having a unidirectional phase separation structure is provided which has a light guide function for crosstalk prevention without using partitions. The phase separation structure includes a first crystal phase and a second crystal phase having a refractive index larger than that of the first crystal phase and which have a first principal surface and a second principal surface, these principal surfaces being not located on the same plane, the first principal surface and the second principal surface have portions to which the second crystal phase is exposed, and a portion of the second crystal phase exposed to the first principal surface and a portion of the second crystal phase exposed to the second principal surface are connected to each other.
