A scintillator for detecting radiation such as x-rays or y-rays, improved with the quantity of light without deteriorating the attenuation time of fluorescence, in which single crystals of tungstate are used and arranged in a crystal orientation that the crystal face where atoms maintain dense configuration and the incident direction of the radiation are in parallel with each other, the cleavage face being selected as the crystal face where atoms maintain dense configuration.
