Title:
SCINTILLATOR AND RADIATION TESTING APPARATUS USING THE SAME
Document Type and Number:
Japanese Patent JP2004238583
Kind Code:
A
Abstract:
To provide a scintillator having stable transparency and exhibiting less deterioration after irradiating with an X-ray, and a radiation detector by using the same.
This scintillator using a sintered material of a rare earth oxysulfide is provided by preparing a solid solution of phosphorus within the crystal of the rare earth oxysulfide and by setting 10-100 ppm amount of the solid solution based on PO4. Thereby, it is possible to stabilize its transparency even on making the scintillator a large size. By stabilizing the transparency, a light emission output is improved.
