Abstract
A solid scintillator having short afterglow and high output, containing a polycrystal containing a crystal of a Gd garnet structure oxide having a composition ratio of formula (1):(MGdQ)JO  (1)where M is at least one element of La and Tb, Q is at least one element of Ce and Pr, J is at least one element selected from Al, Ga, and In, x and y satisfy the relations 0.5≦x<1, and 0.000001≦y≦0.2, and further containing Si and fluorine, where the solid scintillator contains 1 ppm by mass to 1000 ppm by mass of the Si with respect to the Gd garnet structure oxide, and 1 ppm by mass to 100 ppm by mass of the fluorine with respect to the Gd garnet structure oxide. In addition a radiation detector and a tomograph employing the solid scintillator.
