樹脂・蛍光体コンポジットシンチレータ、及びシンチレータアレイ

Document Type and Number:

Japanese Patent JP7405134

Kind Code:

B2

Abstract:

The present invention addresses the problem of providing a scintillator which has excellent impact resistance and favorable workability and moldability. The problem is solved by a resin-phosphor composite scintillator which contains a resin and a phosphor and is capable of converting irradiated radiation into visible light. In this composite scintillator, a brightness retention rate, which is measured 24 hours after 38-minute irradiation with an X-ray to a total irradiation dose of 13 kGy at a distance of 40 mm from a radiation source, is 65% or higher; the Rockwell hardness is 30 HRM or higher; and the content of the resin is not less than 10% by weight.
